Cervical cancer arises from infection of the cervix by HPV. Risk factors include early sexual activity, multiple partners, and smoking. Screening through pap smears can detect pre-cancerous lesions and reduce mortality. Early stage disease is typically treated with surgery or radiation, while advanced disease receives chemoradiation. Surgery options include radical hysterectomy while radiation aims to kill cancer cells. Chemotherapy may be added for recurrent or late stage disease.
Breast cancer is known as the cancer that grow up in the cells of breasts. Breast cancer is the most typical cancer detected in the women. We are celebrating October month as the breast cancer awareness month. It helps the women to get more information about the breast cancer. DDRC SRL diagnostics center in Kerala provides free mammography campaigns for the women in Kerala in this breast cancer awareness month.
Prostate cancer is the most common cancer in men. While some prostate cancers are small and clinically insignificant, others can be rapidly fatal. The percentage of free PSA to total PSA is lower in men with prostate cancer. Microscopically, prostate cancer shows pleomorphic cells in single layer glands without secretions, unlike the normal double layer glands. Gleason scoring is used to grade prostate cancers from 1 to 10 based on their appearance under microscopy. Staging helps determine prognosis, with stage 1 having a 90% 5-year survival rate compared to 10% for stage 4 cancers.
Lynch syndrome, also known as hereditary nonpolyposis colorectal cancer (HNPCC), is caused by a germline mutation in mismatch repair genes and is associated with increased risks of colorectal, endometrial, ovarian and other cancers. The Amsterdam criteria and Bethesda guidelines provide guidance for diagnosing Lynch syndrome based on family history and age of cancer onset. Screening recommendations include annual endometrial biopsy and pelvic exams/ultrasounds to screen for endometrial and ovarian cancers starting at age 30-35 or 5-10 years before the earliest cancer in the family. Risk reducing surgery is recommended after childbearing.
International incidence of colorectal cancer is high, making it the 3rd most common cancer in men and 2nd in women. Risk factors include age over 60, diet high in red/processed meats, family history, smoking, obesity, and certain medical conditions. Colorectal cancer develops from polyps that may bleed, cause bowel changes, or spread. Screening allows early detection and reduces mortality. Treatment involves surgery, chemotherapy, and radiotherapy depending on stage. Prevention focuses on screening, lifestyle changes like diet and exercise, and avoiding risk factors when possible.
I. Screening mammography has become the primary screening tool for breast cancer. It has been shown to decrease mortality rates by detecting cancers early through routine screening.
II. Mammography screening guidelines vary based on risk level. Average risk women are typically recommended annual screening starting at age 40. High risk women may be recommended earlier or more frequent screening, including breast MRI.
III. Risk is determined through factors like family history, genetic testing, density of breast tissue, and use of models like Gail and Tyrer-Cuzick. Women at higher lifetime risk (>20%) may be counseled on additional screening or risk reduction options.

Precancerous lesions identified on biopsy are usually treated with outpatient procedures. The goal of screening and treatment is preventing cervical cancer.
The document discusses breast cancer, including where it originates in the breast, early signs and symptoms, types such as ductal carcinoma in situ and invasive ductal carcinoma, risk factors, diagnosis, treatment options including surgery, radiation therapy, chemotherapy and hormone therapy, nursing interventions, prevention methods, and monitoring for side effects of treatment. Key types discussed in more depth are triple negative breast cancer and inflammatory breast cancer.
Cervical cancer begins in the cells of the cervix and is caused by human papillomavirus (HPV) infection in most cases. Regular cervical screening can detect pre-cancerous changes that may develop into cancer if left untreated. Early stage cervical cancer is often treated with surgery to remove the tumor while more advanced stages may require a combination of surgery, radiation therapy, and chemotherapy. The document discusses risk factors, symptoms, screening, diagnosis, staging, and treatment options for cervical cancer in detail.
Cervical cancer is a major public health problem that is largely preventable. It is the third most common cancer in women worldwide, with over 500,000 new cases and 200,000 deaths each year. While often asymptomatic in early stages, if detected early through screening it can be treated effectively. Screening allows for detection and treatment of precancerous lesions before they develop into invasive cancer. The document discusses the causes, risk factors, natural history, screening methods such as Pap smear and visual inspection with acetic acid, diagnostic tools, and treatment options including ablation, excision and hysterectomy for prevention and management of cervical cancer.
On 4 March 2022, International Human Papilloma Virus (HPV) Day, the Cancer Association of South Africa (CANSA) supports the International Papillomavirus Society’s (IPVS) #OneLessWorry campaign, that aims to raise awareness of the virus, and the tools to overcome it, such as screening and vaccination programmes. HPV can cause cancer and is responsible for almost half a million deaths globally each year.

- Risk factors include multiple sexual partners, young age of first intercourse, and smoking.
- Screening through regular Pap tests can prevent most cervical cancers by detecting pre-cancerous changes early.
- If abnormal cells are detected, a colposcopy and biopsy may be performed for diagnosis.
- Treatment options include surgery, radiation therapy, and chemotherapy depending on the stage of cancer.
- Getting vaccinated against HPV and practicing safe sex can help prevent cervical cancer.
Colorectal cancer begins in the inner lining of the colon or rectum and can spread deeper into the wall of the colon/rectum and to other parts of the body. Risk factors include increasing age, family history, lifestyle factors like smoking, obesity, and lack of physical activity. Symptoms often include changes in bowel habits and bleeding. Screening is recommended regularly beginning at age 50. Treatment depends on the stage and may include surgery, radiation, chemotherapy, and targeted therapies. Prognosis depends on tumor stage and extent at diagnosis.
Breast cancer forms in the breast tissues and spreads mainly through the lymphatic system. Risk factors include gender, age, family history, and certain lifestyle habits. Signs include lumps, skin changes, and nipple discharge. Diagnosis involves exams, mammograms, biopsies and imaging tests. The cancer is staged based on tumor size, lymph node involvement and metastasis. Treatment options include surgery, radiation therapy, drug therapy, and chemotherapy. Radiation therapy is delivered in multiple sessions over several weeks and aims to kill cancer cells while minimizing side effects like skin changes, fatigue and nerve damage.
Cervical cancer develops in the cervix, the lower part of the uterus. It begins as pre-cancerous changes to cervical cells and can progress to cancer. About 10,520 new cases are diagnosed in the US each year, with risks highest for those who are sexually active at a young age or have HPV. Screening via Pap tests can detect cell abnormalities early when treatment is most effective. Treatment options depend on cancer stage and may include surgery, radiation, chemotherapy, or vaccines.
This case discusses a 35-year-old woman named Saher who is concerned about her risk of colorectal cancer due to her family history.

Breast cancer is the most common cancer in women. The breasts are made up of glandular, connective, and fatty tissue. Risk factors include family history, early menarche, late menopause, and obesity. Symptoms may include breast lumps, nipple discharge, and skin changes. Diagnostic tests include clinical breast exams, mammograms, and biopsies of suspicious areas. Treatment depends on cancer type and stage.
Cervical cancer arises from the transformation zone of the cervix where squamous and glandular cells meet. It is caused most commonly by persistent infection with high-risk HPV types. Globally there are over 500,000 new cases and 250,000 deaths annually, though rates have declined in countries with widespread cervical cancer screening. Early lesions are usually asymptomatic while late stages can present with vaginal bleeding or discharge. Screening includes Pap tests and HPV testing to detect pre-cancerous lesions, which if found are typically treated to prevent progression to invasive cancer. Invasive cancers are staged surgically and may require additional chemotherapy or radiation treatment.

Breast cancer screening, prevention and genetic counsellingDrAyush Garg
Mrs. X is a 46-year-old woman concerned about breast cancer risk due to a friend's recent diagnosis. She has no family history of breast cancer herself. The document discusses guidelines for breast cancer screening, genetic screening, and prevention. For Mrs. X, the assistant recommends annual mammography and clinical breast examination in line with screening guidelines for average-risk women over age 40. The benefits of screening increase with age, so annual screening is advised to detect any potential issues earlier.
Breast cancer screening involves various tests to detect breast cancer early in women who have no symptoms. Mammograms are currently the primary screening method, detecting cancers via calcifications or masses on x-rays. Ultrasounds can further examine masses and distinguish cysts from solid tumors. Women at average risk should begin annual mammograms at age 40-44 and continue screening every 1-2 years depending on age. Those at high risk due to family history or genes may begin screening earlier and also receive annual MRIs. Newer tests like molecular breast imaging are being studied but do not replace mammography. Screening aims to find cancer early when treatment is most effective.

It outlines high-risk factors for breast cancer and recommends annual screening starting at age 30-40 for high-risk individuals, including those with BRCA gene mutations or family history. Screening mammography every 1-2 years is recommended for average risk women starting at age 40. Chemoprevention with tamoxifen or raloxifene can lower breast cancer risk in high risk postmenopausal women. Genetic testing guidelines are also provided.
This document provides guidelines for moderate sedation/analgesia (conscious sedation). It defines levels of sedation from minimal to general anesthesia. Moderate sedation involves patients responding purposefully to verbal commands with spontaneous breathing. The guidelines discuss patient evaluation, monitoring, personnel, equipment, drugs and discharge criteria for providing moderate sedation. Proper patient screening, credentialed practitioners and personnel, appropriate facilities and emergency equipment are emphasized to minimize risks while allowing benefits of sedation for certain medical procedures.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Blood units are transported from the central blood bank to the blood bank at BB Meegat General Hospital. Upon receipt, staff must monitor and record the temperature of transport containers to ensure blood products are within specified temperature ranges. Staff also inspect each blood unit, checking for hemolysis, leakage, damage, and verifying ABO and Rh typing. Units are then organized by blood type and labeled as ready for cross-match or reserved. Daily preservation tasks include temperature monitoring, checking expiration dates, and inventory levels. Blood is then delivered to hospital departments as needed upon receiving transfusion request forms and completing cross-match details.
Post covid-19 syndrome, also known as long covid, refers to symptoms that can persist for weeks or months after recovery from the initial acute illness. While people are not infectious during this time, there is no agreed upon definition. A wide range of long-term symptoms have been reported, including fatigue, chest pain, muscle pain, loss of smell, and depression. Certain groups, such as older individuals, those who are obese, and people with diabetes or lung/kidney disease, appear to be at higher risk of developing long-term effects from covid-19.
Sepsis and septic shock guidelines 2021. part 1MEEQAT HOSPITAL
1. Sepsis is a critical imbalance between oxygen supply and demand that can affect any system. Serum lactate levels rise in response to tissue hypoxia and higher levels correlate with poorer outcomes.
2. Guidelines recommend screening high-risk patients for sepsis and using standard treatment protocols. Blood lactate should be measured in suspected cases and treatment begun immediately.
3. Fluid resuscitation of at least 30mL/kg should begin within 3 hours, guided by dynamic measures over static parameters alone. Antimicrobial therapy should also begin immediately or within 1-3 hours depending on risk level and presence of shock.
sepsis SSC 2021 Updates Ventilation and additional therapyMEEQAT HOSPITAL
This document discusses ventilation strategies and additional therapies for sepsis patients with respiratory failure. It covers conservative oxygen targets, types of respiratory failure, benefits of non-invasive ventilation (NIV) and positive airway pressure (PAP), and risks of NIV. The Berlin definition for acute respiratory distress syndrome (ARDS) severity is also presented. Recommendations are provided for mechanical ventilation settings and various treatments for sepsis patients.
This document discusses sepsis scoring systems. It describes the historical definitions and consensus guidelines for sepsis from 1991 to 2016. It also discusses the Surviving Sepsis Campaign from 2004 to 2008. The document compares different scoring systems for sepsis like SIRS, SOFA, qSOFA, and MEWS and explains which are best for identifying sepsis in ICU versus non-ICU patients. It outlines the pathogens commonly associated with sepsis and trends in incidence and mortality.
This document defines medication error and outlines procedures for reporting medication errors. It also lists common types of medication errors including prescribing errors, omission errors, wrong time errors, and improper dose errors. Causes of errors include look-alike and sound-alike drug names, illegible handwriting, and unapproved abbreviations. Nursing responsibilities in preventing errors and standard precautions are discussed.
CRRT is a continuous renal replacement therapy that provides a gentler form of dialysis for critically ill patients. It works through slow, continuous removal of waste and fluid over multiple days rather than the typical 4 hour sessions of hemodialysis. This puts less stress on the heart. CRRT can be delivered through various modes including continuous venovenous hemofiltration, hemodialysis, or hemodiafiltration that utilize diffusion, convection, or both to clean the blood. Anticoagulation is required to prevent clotting of the dialysis circuit and can include regional citrate or low-dose heparin.
Deep vein thrombosis (DVT) is a blood clot that forms in the deep veins, usually in the legs. Virchow's triad of venous stasis, hypercoagulability, and endothelial injury can lead to thrombus formation. Risk factors include age, immobilization, surgery, cancer, and genetic factors. Patients may experience pain, swelling, warmth, and tenderness. Diagnosis involves a Wells score, D-dimer test, ultrasound or venography. Treatment is anticoagulation with heparin, low molecular weight heparin, fondaparinux, or warfarin to prevent pulmonary embolism. Long-term anticoagulation and compression stockings can help prevent
This document discusses bed sore management and prevention. It defines bed sores as injuries to the skin and underlying tissues caused by prolonged unreleived pressure. Risk factors include advanced age, malnutrition, physical disability, and chronic illness. Bed sores are staged from Stage 1 involving changes in skin color to Stage 4 involving full thickness tissue loss reaching muscle, bone and tendon. Treatment involves surgical procedures like debridement, dressings, antibiotics, regular posture changes, diet, and hygiene to prevent further complications. The nursing perspective focuses on assessing risk factors, inspecting the skin and environment, staging any sores present, and ensuring regular care and prevention measures.
Chest intubation indications,precautions and managementMEEQAT HOSPITAL
Chest tube insertion or thoracostomy is a life-saving procedure where a plastic tube is inserted into the pleural cavity to drain fluid, air, or both. It can be performed at the bedside, and every surgical/ER resident is expected to be trained and able to perform it. The document provides details on indications for the procedure, equipment needed, patient positioning, steps for insertion, post-procedure care and monitoring, potential complications, and criteria for tube removal.

This document provides guidelines for moderate sedation/analgesia (conscious sedation). It defines the different levels of sedation from minimal to general anesthesia. Moderate sedation is described as a drug-induced depression where patients can respond to commands. It outlines safety procedures for patient evaluation, monitoring during procedures, qualifications of medical personnel, facilities requirements, and discharge criteria. The goal is to allow clinicians to provide sedation benefits to patients safely by minimizing risks.

4. Overview
• What is breast cancer?
• What are some Causes and risks?
• What are the Symptoms?
• How about some Epidemiology?
• What’s the deal with BRCA1 and BRCA2?
• Are there Early Detection and Treatments?
• Do I have a check list I can follow?
• Conclusion!
5. What is Breast Cancer?
• Breast cancer primarily effects women but about
1 percent of all cases effect men
• Breast cancer is the second leading cause of
death in women next to lung cancer
• One out of nine women in the US will develop
breast cancer in their lifetime
– One out of twenty in 1960
• An abnormal, uncontrolled cell growth arising in
the breast tissue
6. The breast
• The breasts are made of fat,
glands, and connective
(fibrous) tissue
• The breast has several lobes,
which are divided into lobules
and end in the milk glands
• Tiny ducts run from the many
tiny glands, connect together,
and end in the nipple
7. The breast
• These ducts are where 78% of
breast cancers occur. This is
known as infiltrating ductal cancer
• Cancer developing in the lobules is
termed infiltrating lobular cancer.
About 10-15% of breast cancers
are of this type.
• Another type of breast cancer is
inflammatory breast cancer (Often
Misdiagnosed and dangerous)
8. Inflammatory Breast Cancer
• Rare, serious, aggressive
form of breast cancer
• Looks red (erythema),
feels warm
• Thickening of skin
• Ridges, welts and hives
may be observed
• Skin may look wrinkled
• Sometimes misdiagnosed
as infection
9. • Personal or family
history
• Not having children
• Having first child after
age 30
• Radiation therapy to
chest/upper body
• Overweight or obese
• Age
• Late menopause
• Diets high in saturated
fat
• Your sex
• Estrogen replacement
therapy
Causes and Risks
10. Causes and Risks
Although breast cancer can occur at any age
the risk factor increases the older one gets.
– The average woman at age 30 has 1 chance in
280 of developing breast cancer in the next 10
years
– This chance increases to 1 in 70 for a woman
aged 40
– By age 50 the chances are1 in 40
– A 60-year-old woman has a 1 in 30 chance of
developing breast cancer in the next 10 years.
11. Causes and Risks
• Shields
– Being older at first menstration and having an
earlier menopause lowers risk
– Having children before the age of 30 helps.
Having no children increases risk.
– Physically active women may have a lower
risk.
– Preemptive mastectomy
12. Symptoms
• Early breast cancer has little or no symptoms. It is not
painful.
• Breast discharge, especially if only from one breast or
bloody
• Sunken nipple, Though a common variant of normal
nipples a new development should cause concern
• Redness, changes in texture, and puckering. Usually
caused by skin disease but sometimes can be
associated with breast cancer.
• Lumps on or around breast. Most lumps are not
cancerous
• Other lumps around the under arm or collarbone
which don’t go away
• Loss of smell?
13. Metastasis
• The most common place for breast cancer
to metastasize is into the lymph nodes
under the arm or above the collarbone on
the same side as the cancer.
• Brain
• Bones
• Liver
14. Epidemiology
• An estimated 182,000 new cases of breast
cancer are expected to occur in the United
states during 2015.
• The rate of new cases have increased
since 1980 but rates have slowed down
since the 1990’s.
• About 1690 new cases of breast cancer
are expected in men.
15. Epidemiology
• An estimated 40,460 deaths (40,000 women,
460 men) are anticipated from breast cancer in
2015.
• Mortality rates declined 1.4% per year during
1989-1995 and by 3.2% afterwards.
• Largest decrease was in younger women for
both Caucasians and African Americans.
16. Epidemiology
• The 5 year survival rate for localized
breast cancer has increased from 72% in
the 1940’s to 97 percent today.
• Regionally spread cancer drops the rate to
78%
• Distant metastases drops the survival rate
even lower to 23%
19. BRCA1/BRCA2
• BRCA1 discovered in 1994
• BRCA2 discovered in 1995
• 5-10% of all breast cancer cases are
linked to this gene.
• Having a single copy of either mutated
gene appears to confer about an 80%
chance of developing breast cancer.
20. BRCA1/BRCA2
• BRCA1 is located on
chromosome 17
• BRCA2 is located on
Chromosome 13
• When found, many
researchers thought it
would shed light on
breast cancer in those
patients who did not
have the mutated
gene.
21. What does BRCA1&BRCA2 do?
• Both genes help mediate damage to cell’s
DNA. Exactly how though is still being
studied.
• These genes are tentatively linked to an
increased risk for also pancreatic,
prostate, and ovarian cancer.
• Puzzle… Why is breast tissue so
susceptible?
22. BRCA1/BRCA2
• A possible explanation is estrogen.
• Studies on mice without BRCA but treated
with excess estrogen were found to over
stimulate genes and proteins in a
hormonal activating pathway.
• Further testing will show whether it affects
tumor formation.
• But why mostly women and not many
men? Men have estrogen too!!!
23. BRCA1/BRCA2
• The two X deal
• During embryonic development one
chromosome is randomly shut down. No
double dose of X
• Cells with mutated BRCA1 have been
found to prevent fully shutting down the
second X chromosome.
24. BRCA1/BRCA2
• In men??
• Study shows that BRCA2 mainly causes
increase of risk
• 7% risk of breast cancer by age 80
• Association between BRCA1 and MBC is less
clear
• Female first-degree relatives of MBC cases are
at increased risk of breast cancer
25. BRCA1/BRCA2
• Women who have the BRCA1 gene tend to develop
breast cancer at an early age
• Possible BRCA carriers are females whose mother
and grandmother have had breast cancer
• Testing for these genes is expensive and frequently
not covered by insurance
• Women who test positive may have trouble getting or
keeping health insurance.
26. Early detection
• Early detection is the key!
– Self/Doctor examinations
– Mammography
– Ultrasound
– MRI
– Biopsy
– Self VS Mammography VS Ultrasound VS
MRI VS Biopsy
27. Early detection
• Breast self/doctor examination
– includes visual inspection and
careful feeling of the breasts, the
armpits, and the areas around the
collarbone.
– Looking for lumps or abnormalities
around the breast.
– Most lumps are NOT cancerous
– Best time for examination is
immediately after the monthly
period
• Not 100% accurate
28. Early detection
• Mammography
– X-ray picture of the
breast taken from
several angles by
compressing the
breast horizontally,
diagonally, and
sometimes vertically.
– Not 100% accurate
31. Early detection
• Classification systems ACR 5-tier system
• BIRADS
BIRADS or 'BI-RADS stands for Breast Imaging Reporting and
Data System
– BIRADS 0: Assessment incomplete
– BIRADS I: Negative
– BIRADS II: Benign finding
– BIRADS III: Probably benign finding
– BIRADS IV: Suspicious abnormality
– BIRADS V: Highly suspicious of malignancy
– BIRADS VI: Known biopsy proven
• Nottingham classification
• Tabar 5-tier grading system
32. Early detection
• Ultrasound
– Usually done in addition to the
mammogram.
– Shows whether a mass is
filled with fluid or solid.
Cancers are solid.
– Not 100% accurate
33. Early detection
• MRI
– Magnetic resonance
imaging.
– Differentiates diseased
or dying tissue from
normal healthy tissue
– Almost 100% accurate
34. Early detection
• Biopsy
– take a very small
piece of tissue from
the body for
examination and
testing.
– examined by a
pathologist
– 100% accurate
37. Early detection
• Self/doctor exams usually only feel lumps
after tumor is about 1 inch diameter
• Mammography & ultrasound detect tumors
at about ¼ inch
• MRI uses cell contrast for excellent
detection but costs 8-20 times more then
standard mammography
• 100% assurance on any suspicious lumps
can only be obtained by a biopsy
39. Early detection
• The stages 0-IV
– Stage 0 is noninvasive breast cancer, that is, carcinoma in
situ with no affected lymph nodes or metastasis. This is the
most favorable stage to find breast cancer.
– Stage I is breast cancer that is less than three quarters of an
inch in diameter and has not spread from the breast.
– Stage II is breast cancer that is fairly small in size but has
spread to lymph nodes in the armpit OR cancer that is
somewhat larger but has not spread to the lymph nodes.
40. Early detection
• The stages 0-IV
– Stage III is breast cancer of a larger size (greater
than 2 inches in diameter), with greater lymph node
involvement, or of the inflammatory type.
Spreading to other areas around the breast.
– Stage IV is metastatic breast cancer: a tumor of any
size or type that has metastasized to another part of
the body (ex. bones, lungs, liver, brain). This is the
least favorable stage to find breast cancer.
42. Therapeutic Vaccines
• Treat existing cancers
• Under development
• Melanoma, lung, ovarian, prostate tumors
• “Kick-start” immune system
• Prevent further growth of existing cancers
• Block recurrence of treated cancers
• Kill cancer cells not destroyed by previous
treatment
43. HER-2/neu
• Growth-stimulating protein
• Normal cells express a small
amount on their plasma
membranes
• On surface of breast cancer
cells
• Sends messages from cell to
“growth factors” outside cell
• Overabundant on surface of
cancer cells in 30% of
women with breast cancer
44. HER-2/neu Vaccine
• Targets HER-2/neu protein
• Made from small protein pieces likely to
trigger an immune response
• Contains a drug that helps increase white
blood cell counts
• Monthly shots for six months
• No serious side effects
45. Telomerase Peptide
• Enzyme
• Found in over 90% of breast cancer tumors
• Current vaccine research
– Study measures tumor cell shrinkage in patients
after immune response to an antigen
• Generate white blood cell attack
46. Telomerase Peptide Vaccine
• Antigen/adjuvant vaccine
– Uses specific peptide to mobilize the immune system
• Administered over seven months
• Produced immune response in breast and prostate
cancer patients
– Temporary tumor regression
– Little toxicity
47. Theratope Vaccine
• Used for metastatic breast cancer
• Stimulates patient’s immune response to tumor
STn marker
– Cancer associated carbohydrate antigen
– Vaccine contains synthetic form
• Phase III tests inconclusive
• Small subset showed improvement in survival
48. Herceptin
• Type of biologic therapy
• Breast cancer treatment
drug
• Monoclonal antibody
therapy
• Blocks HER-2/neu
• Effective in metastatic HER-
2/neu positive breast cancer
• Little effect with HER-2/neu
negative breast cancer
49. Surgery
• Lumpectomy
– removal of the cancerous tissue and a
surrounding area of normal tissue
• Simple mastectomy
– removes the entire breast but no other
structures
• Modified radical mastectomy
– removes the breast and the underarm lymph
nodes
50. Surgery
• Radical mastectomy
– removal of the breast and the underlying
chest wall muscles, as well as the underarm
contents.
– This surgery is no longer done because
current therapies are less disfiguring and
have fewer complications.
52. Treatment
• BRCA1/BRCA2?
– No “treatment”
– Mastectomy cuts risk by 90%
– Hysterectomy slashes another 50%
– Tamoxifen
• anti-estrogen drug
• Lowers risk of diagnosis of benign tumors Influenced by
estrogen
• Reduces risk about 28%
• May reduce need for biopsies in high-risk women
• Intervenes before invasive cancer begins
53. The checklist
• Age 20-39
– Monthly self breast
exam
– Yearly breast exam by
doctor
– Mammogram every
2-3 years
• Age 40+
– Monthly self breast
exam
– Breast exam by doctor
every 6 month
– Mammogram once a
year
– Skin exam yearly
54. Conclusion
• The biggest risks for breast cancer are age, sex,
and genetics
• Second highest cancer killer in women
• Rates of new cases have slowed
• BRCA1/BRCA2 only effect 5% of cases
• Several early detection techniques and devices
• Vaccines show promise but are not a solution
• Surgery helps prevent reoccurrence.
