most common cancer" (new cases diagnosed):
•Globally:
• Breast cancer and lung cancer are tied for the
most common, with each contributing around
12% of new cases diagnosed in 2020 [WHO].
•In Men:
• Lung cancer takes the top spot, contributing to
over 15% of new cancers in men globally
[WCRF].
the most common cancers that I introduced to you
lung cancer 2
Lung cancer is a malignant tumor
that begins in the lungs. It is the
leading cause of cancer death for
both men and women in the United
States and around the world. Lung
cancer develops when cells in the
lungs grow uncontrollably and
form tumors. These tumors can
invade healthy tissue and spread to
other parts of the body.
lung cancer 3
There are two main types of lung
cancer:
•Non-small cell lung cancer
(NSCLC):This is the most common
type of lung cancer, accounting for
about 80% of all cases. NSCLC can
be further classified into different
subtypes, such as
adenocarcinoma
• squamous cell carcinoma,
and large cell carcinoma.
Small cell lung cancer (SCLC):
This type of lung cancer is less common
than NSCLC, but it is generally more
aggressive. SCLC often spreads to other
parts of the body at an early stage.
lung cancer 4
The main cause of lung cancer is smoking tobacco. In fact,
about 80% of lung cancer deaths in the United States
smoking. Other risk factors for lung cancer include exposure to
secondhand smoke, radon gas, and asbestos.
The symptoms of lung cancer can vary depending on the size and
location of the tumor. However, some common symptoms
include:
1. A cough that doesn't go away
2. Shortness of breath
3. Chest pain
4. Blood coughing up blood
5. Wheezing
6. Unexplained weight loss
7. Fatigue
8. Loss of appetite
lung cancer 5
the most common cancers that I introduced to you.
Let's talk about lung cancer. The lungs sit in the chest
and deliver air or oxygen to the blood. Lung cancer is
the most common cancer in men and women,
approximately 220,000diagnoses per year in the US.
Somewhere between 1.5 and2 million people are
diagnosed worldwide with cancer, and it is an
extremely lethal disease. It is the leading cause of
cancer death approximately 160,000 deaths per year in
the U.S and 1.3 million worldwide. ,

lung cancer 7
Treatment for lung cancer depends
on the type and stage of the cancer,
as well as the patient's overall
health. Treatment options may
include surgery, chemotherapy,
radiation therapy, and targeted
therapy.
Early detection and
treatment of lung cancer
is essential for improving
the chances of a
successful outcome.
lung cancer 8
We do a very poor job of being able
to cure lung cancer, because by the
time it's diagnosed, it is too far
advanced to be treated
lung cancer 9
locally for cure with surgery or
radiation. It is a lethal disease.
There are many sub types of lung
cancer but 85% of them are called
non-small-cell lung cancers or
NSCLC. They come in various
histologies . Adenocarcinoma is the
most common 40%. But then,
there's squamous cell carcinoma
and large cell carcinoma.
lung cancer 10
What are the risk factors for lung cancer?
Smoking, smoking, smoking. Let me repeat,
smoking, smoking, smoking.
87% of lung cancer deaths in men
and
70% in women are likely caused by smoking.
lung cancer 11
lung cancer 12
Risk of developing lung cancer
is 25-times higher In smokers
as compared to nonsmokers.
Many other lung cancers are
linked to secondhand smoke.
Let me repeat the number
one risk factor for lung cancer is smoking, smoking, smoking.
Primary smoking and secondary inhalation of smoke when you are
exposed to it.
lung cancer 13
This is why in every where smoking has been banned in
restaurants and most public places because it is well-
known that secondhand smoke is linked to a risk of lung
cancer.
Other risk factors include radon, asbestos, arsenic
, radioactive ores like uranium and inhaled chemicals.
In other words inhaled substances that damage the lungs.
This makes lung cancer prevention fairly straightforward.
Stop smoking, do not let yourself be exposed to
secondhand smoke.
Stop smoking, do not let yourself be exposed to second
hand smoke. If you can decrease exposures ,for example
wearing a air mask if you're a uranium miner, you can
decrease your chance of developing lung cancer
lung cancer 14
• to prevent lung cancer. Many studies have been
done looking to try to understand, can we screen
for lung cancer?
• Many things have been tried
• including x-rays
• computed tomography scans
• sputum tests
lung cancer 15
Who should get lung cancer
screening?
The United States Preventive
Services Task Force (USPSTF)
recommends annual screening for
lung cancer with low-dose
computed tomography (LDCT) for
adults aged 50 to 80 years who
have a 20 pack-year smoking
history and currently smoke or
have quit within the past 15 years.
What is low-dose CT (LDCT)?
LDCT is a type of X-ray that uses a
lower dose of radiation than a
traditional CT scan. During an LDCT
scan,
you lie on a table
while an X-ray machine rotates around
you, taking detailed pictures of your
lungs. The scan only takes a few
minutes and is not painful.
lung cancer 16
Lung cancer is the leading cause of
cancer death. According to
the American Lung Association,
the average lung cancer five-year
survival rate is 18.6 percent.
Only 16 percent of lung cancers
are diagnosed at an early stage
more than half of people with lung
cancer die within one year of being
diagnosed.
https://www.lung.org/
lung cancer 17
While treatments of more advanced-
stage cancers with targeted therapy
immunotherapy have come a long way
the best tool in the fight against cancer
deaths is early diagnosis through low-
dose CT screening before symptoms
appear.
Symptoms occur mainly in late-stage lung
cancer,”. “Thus, the best way to find early-
stage lung cancer is by enrolling in an
annual screening program.”
lung cancer 18
https://profiles.mountsinai.org/claudia-i-
henschke#about
lung cancer 19
There was a large study, called the National Lung Screening Trial, that
looked at men and women 55 to 74 years old who were otherwise in
good health, who had at least a 30 pack-year smoking history.
That means they smoked at least one pack of cigarettes per day for 30
years. That means they have a 30pack-year smoking history.
If they have smoked half a pack a day for 30 years they would have a
15pack-year smoking history. If you smoked two packs a day per year it
would be a 60-pack year smoking history. The other way to be eligible
for this trial was to be still smoking or to have quit smoking within the
last 15 years.

lung cancer 21
If a man or woman meets those
criteria, it was noted that they could
be screened with a CAT scan yearly
for three years in a row to look for
early lung cancers. And that this
could actually detect lung cancers
and remove them before they
became lethal.

  • 8. Treatment for lung cancer depends on the type and stage of the cancer, as well as the patient's overall health. Treatment options may include surgery, chemotherapy, radiation therapy, and targeted therapy. Early detection and treatment of lung cancer is essential for improving the chances of a successful outcome. lung cancer 8

They come in various histologies . Adenocarcinoma is the most common 40%. But then, there's squamous cell carcinoma and large cell carcinoma. lung cancer 10
  • 11. What are the risk factors for lung cancer? Smoking, smoking, smoking. Let me repeat, smoking, smoking, smoking. 87% of lung cancer deaths in men and 70% in women are likely caused by smoking. lung cancer 11
  • 12. lung cancer 12 Risk of developing lung cancer is 25-times higher In smokers as compared to nonsmokers. Many other lung cancers are linked to secondhand smoke. Let me repeat the number one risk factor for lung cancer is smoking, smoking, smoking. Primary smoking and secondary inhalation of smoke when you are exposed to it.
  • 13. lung cancer 13 This is why in every where smoking has been banned in restaurants and most public places because it is well- known that secondhand smoke is linked to a risk of lung cancer. Other risk factors include radon, asbestos, arsenic , radioactive ores like uranium and inhaled chemicals. In other words inhaled substances that damage the lungs. This makes lung cancer prevention fairly straightforward. Stop smoking, do not let yourself be exposed to secondhand smoke. Stop smoking, do not let yourself be exposed to second hand smoke. If you can decrease exposures ,for example wearing a air mask if you're a uranium miner, you can decrease your chance of developing lung cancer
  • 14. lung cancer 14 • to prevent lung cancer. Many studies have been done looking to try to understand, can we screen for lung cancer? • Many things have been tried • including x-rays • computed tomography scans • sputum tests
  • 15. lung cancer 15 Who should get lung cancer screening? The United States Preventive Services Task Force (USPSTF) recommends annual screening for lung cancer with low-dose computed tomography (LDCT) for adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. What is low-dose CT (LDCT)? LDCT is a type of X-ray that uses a lower dose of radiation than a traditional CT scan. During an LDCT scan, you lie on a table while an X-ray machine rotates around you, taking detailed pictures of your lungs. The scan only takes a few minutes and is not painful.
  • 16. lung cancer 16 Lung cancer is the leading cause of cancer death. According to the American Lung Association, the average lung cancer five-year survival rate is 18.6 percent. Only 16 percent of lung cancers are diagnosed at an early stage more than half of people with lung cancer die within one year of being diagnosed. https://www.lung.org/
  • 17. lung cancer 17 While treatments of more advanced- stage cancers with targeted therapy immunotherapy have come a long way the best tool in the fight against cancer deaths is early diagnosis through low- dose CT screening before symptoms appear. Symptoms occur mainly in late-stage lung cancer,”. “Thus, the best way to find early- stage lung cancer is by enrolling in an annual screening program.”
  • 19. lung cancer 19 There was a large study, called the National Lung Screening Trial, that looked at men and women 55 to 74 years old who were otherwise in good health, who had at least a 30 pack-year smoking history. That means they smoked at least one pack of cigarettes per day for 30 years. That means they have a 30pack-year smoking history. If they have smoked half a pack a day for 30 years they would have a 15pack-year smoking history. If you smoked two packs a day per year it would be a 60-pack year smoking history. The other way to be eligible for this trial was to be still smoking or to have quit smoking within the last 15 years.
