TECHNIQUE OF BREAST EXAMINATION
Pain --varying with menstrual cycle --independent of menstrual cycle Lump in the breast --Hard lump -- Firm, poorly defined lump or lumpiness --Soft lump Skin changes in the breast --Skin dimpling or tethering --Visible lump --Peau d’orange (kulit limao) --Redness --Ulceration Nipple disorders --Recent inversion or change in shape --“Eczema” (rash involving nipple or areola, or both) --Nipple discharge Milky Clear Green Blood-stained
NIPPLE DISORDERS --Recent inversion or change in shape suggests a fibrosing underlying lesion such as a carcinoma or mammary duct ectasia but can be malignancy (refer urgently) --“Eczema” (rash involving nipple or areola, or both) if unilateral and persistent, this is the classic sign of Paget’s desease of the nipple, a presentation of breast ca (refer urgently if not responding to treatment) --Nipple discharge1. Milky—pregnancy of hyperprolactinaemia2. Clear – physiological3. Green –perimenopausal, duct ectasia, fibroadenotic cyst4. Blood-stained –possible carcinoma or intraduct papilloma (refer urgently)

CLINICAL CHARACTERISTICS OF ABREAST LUMP Solitary or multiple Size – in cm Location – quadrant of breast or clock face Contour – smooth and round/ovoid (likely to be benign) or firm/ hard (probable malignancy) Mobility – mobile or fixed Associated changes – skin/nipple retraction, skin tethering, bloody nipple discharge, erythema Axillary lymphadenopathy – enlarged and mobile or enlarged and fixed
1.INHERITED BREASTCANCERBetween 5-10% of breastcancer is inherited from afamily member.This means that themajority of women thatare diagnosed with breastcancer do not have thegenetic mutation. This figure shows that one out of every 10 women willResearch has suggested obtain breast cancer by inheriting a gene from a family member.women who are diagnosedwith breast cancer at ayoung age (less than 45)usually inherited.
INHERITEDGENESBRCA1 (Breast Cancer 1)BRCA2 (Breast Cancer 2)TP53 geneATM gene
BRCA 1 AND BRCA 2Both of these genes code for DNA repair.If a woman has a mutation on either one of thesegenes, the risk of her getting breast cancerincreases from 10% to 80% in her lifetime.Mutations in BRCA1 or BRCA2 account for 40-50%of all cases of inherited breast cancer.These genes are also associated with ovarian cancerin women and prostate cancer in men.These genes can be inherited either from themother or the father.

DIAGRAM OF THEBREASTThe breast is a glandularorgan.It is made up of a network ofmammary ducts.Each breast has about 15-20mammary ducts that lead tolobes that are made up oflobules.The lobules contain cells thatsecrete milk that arestimulated by estrogen andprogesterone which areovarian hormones.
IN SITU BREASTCANCERIn Situ Breast Cancer remains within the ducts orlobules of the breasts.This type of cancer is only detected by mammograms– not by a physical examination.If the cancer is in the duct it is called DuctalCarcinoma in situ.If the cancer is in the lobule of the breast, it iscalled Lobular Carcinoma in situ. This type of cancer is most common among pre-menopausal women. There is also a slight chance that if a woman has this type of cancer she is at risk that it would occur in the other.
INFILTRATING BREAST CANCER Breast cancer is considered infiltrating or invasive if the cancer cells have penetrated the membrane that surrounds a duct or lobule.Breast cancer cells cross the lining ofthe milk duct or lobule, and begin toinvade adjacent tissues. This type of This type of cancercancer is called "infiltrating cancer." forms a lump that canIn this picture, you can see the breast eventually be felt by acancer cells invading the milk duct. physical examination.

THE EFFECT OF TUMOR SIZE ON SURVIVAL As tumor size increases, the chance of survival decreases. Tumor Size Survival
CANCER MADE?Diagnostic tests– all breast lumps or suspected carcinoma Triple assessment 1.Clinical examination 2.Radiological assessment -Mammography usual particularly over age 35y. -Ultrasound sometimes used under age 35 because increased tissue density reduces the sensitivity and specificity of mammography 3.Cytological assessment Fine needle aspiration cytology (FNAC) or occasionally, core needle biopsy Staging investigations 1. Liver ultrasound 2.Chest X-Ray 3.Bone scan 4.Specific investigations for organ-specific suspected metastases.
MAMMOGRAMA Mammogram is a X-ray ofthe breast that takespictures of the fat, fibroustissues, ducts, lobes, andblood vessels.When should a mammogrambe performed? If a lump has been found during self-examination or by a physician Younger women who have a strong history of breast cancer in their family All women over forty Women who have had previous diagnosis of breast cancer.
WHAT MAMMOGRAMSSHOWTwo of the most important mammographicindicators of breat cancers Masses Microcalcifications: Tiny flecks of calcium – like grains of salt – in the soft tissue of the breast that can sometimes indicate an early cancer. 42
DETECTION OF MALIGNANTMASSESMalignant masses have a more spiculated appearance benign malignant 43

TREATMENTS OFBREAST CANCER
MEDICAL TREATMENTNON- METASTASIS DISEASE Adjuvant to reduce the risk of systemic relapse usually after primary surgery. Occasionally used as treatment of choise in elderly or those unfit/inappropriate for surgery Endocrine Therapy1. Anti-estrogens (e.g tamoxifen, LHRH antagonists, aromatase inhibitors)2. Most effective in ER +ve tumours Chemotherapy1. Anthracyclines, cyclophosphamide,5-FU, methotrexate2. Offered to patients with high risk features (+ve nodes, poor grade)
MEDICAL TREATMENTMETASTASIS DISEASE Palliative to increase survival timeEndocrine TherapyAs aboveChemotherapyAnthracyclines, tanaxestRadiotherapyTo reduce pain of bony metastases orsymptoms from cerebral or liver disease
SURGERY MAINSTAY FOR NON METASTASIS DISEASE Mastectomy(radical,modified radical simple) Breast conservation A mastectomy is the (lumpectomy, wide local surgical removal of the excision, quadrantectomy) breast, non-protruding In this surgical procedure, breast tissue, the lymph the breast is conserved and nodes in the armpits and the tumor is removed. some pectoral muscle. Radiation commonly follows a Breast reconstruction lumpectomy to try to rid the surgery may be body of any other cancerous conducted after the cells. removal of the breast.
BREAST CA Wide local excision-commenest procedure -breast conserving provided breast is adequate size and tumour location appropriate (not central/retro-areolar) -usually combined with local radiotherapy Simple mastectomy-best treatment and cosmetic result Surgical management of regional lymph nodes-Axillary node sampling-Axillary node clearance-Sentinel node biopsy Usually the first axillary node to receive lymphatic drainage from the tumour. Before operation, a blue dye and a radiotracer are injected into subareolar areas and at operation the sentinel node is identified visually and by using a device to detect radioactivity. Surgery for metastastic disease: limited to procedures for symptomatic control of local disease (e.g mastectomy to remove fungating tumour)
FOR BREASTCONSERVATIONSURGERY Single lesion clinically and mammographically Tumour not larget than 3cm (4cm in larger breast) No extensive in situ component Tumours more than 2cm away from nipple/areola Lesion of lower histological grade No extensive nodal involvement

FATResearch shows that dietary fat shouldbe 20% or less in order to gainmeaningful protection against cancer.Fat cells make estrogen, which promotesbreast cancer.Diets high in fat are associated with theincreasing breast density in mammograms,which makes interpretation moredifficult.
FIBERFiber provides protection against breastcancer because it has a mechanism thatdecreases the amount of estrogen in thebody.The amount of fiber in the diet affects theactivities of intestinal bacteria, which affectsthe amount of reabsorbed estrogens.
ANTIOXIDANTNUTRIENTSAntioxidants are important in fightingbreast cancer because they can disarmcancer-causing substances called freeradicals.Vitamin CVitamin EBeta-caroteneVitamin ASelenium
OTHER PREVENTATIVE MEASURES Early Detection!!!! Exercise No Smoking!! Good Diet
