Estimated new cases and deaths from lung
cancer (non-small cell and small cell combined) in the United States in
2007: New Cases - 213,380, Deaths - 160,390
Chest X-rays - A new study from the National Cancer
Institute (NCI), part of the
National Institutes of Health, shows that screening for lung cancer
with chest X-rays can detect early lung cancer but also can produce
many false-positive test results, causing needless extra tests.
National Lung Screening Trial - Both chest
X-rays and spiral CT scans
have been used to find lung cancer early. So far, neither chest X-rays
nor spiral CT scans have been shown to reduce a person's chance of
dying from lung cancer. This study will aim to show if either test is
better at reducing deaths from this disease.
Secondhand smoke is responsible for an
estimated 3,000 lung cancer deaths among U.S. nonsmokers each
Tobacco smoke contains thousands of
chemical agents, including over 60 substances that are known to cause
The risk of developing smoking-related
cancers, as well as noncancerous
diseases, increases with total lifetime exposure to cigarette
Smoking cessation has major and
immediate health benefits, including
decreasing the risk of lung and other cancers, heart attack, stroke,
lung disease .
- Cigar and pipe smokers have a higher risk of lung
nonsmokers. The number of years a person smokes, the number of pipes or
cigars smoked per day, and how deeply the person inhales all affect the
risk of developing lung cancer. Even cigar and pipe smokers who do not
inhale are at increased risk for lung, mouth, and other types of cancer.
The Truth About “Light”
Cigarettes - Key points
- The lower tar and nicotine numbers on light cigarette
packs and in ads are misleading.
- Light cigarettes trick the smoking machines so that
they record artificially low tar and nicotine levels.
- Light cigarettes provide no benefit to smokers’
- Resources are available for people who want to quit
Radon is an invisible, odorless, and tasteless radioactive gas that
occurs naturally in soil and rocks. It can cause damage to the lungs
that may lead to lung cancer. People who work in mines may be exposed
to radon and, in some parts of the country, radon is found in houses.
The risk of lung cancer is even higher among people who have been
exposed to radon who also smoke.
- Asbestos is the name of a group of minerals that occur naturally as
fibers and are used in certain industries. Asbestos fibers tend to
break easily into particles that can float in the air and stick to
clothes. When the particles are inhaled, they can lodge in the lungs,
damaging cells and increasing the risk for lung cancer. Studies have
shown that workers who have been exposed to large amounts of asbestos
have a risk of developing lung cancer that is 3 to 4 times greater than
that for workers who have not been exposed to asbestos. This exposure
has been observed in such industries as shipbuilding, asbestos mining
and manufacturing, insulation work, and brake repair. The risk of lung
cancer is even higher among asbestos workers who also smoke.
- Certain lung diseases, such as tuberculosis (TB), increase a person's
chance of developing lung cancer. Lung cancer tends to develop in areas
of the lung that are scarred from TB.
History - A person who has had lung cancer once is more
likely to develop a
second lung cancer compared with a person who has never had lung cancer.
Quitting smoking will greatly reduce your risk
of developing lung cancer.
About 10 years after quitting, an ex-smoker’s risk of dying from
lung cancer is 30 to 50 percent less than the risk of those who
continue to smoke.
Quitting smoking will benefit
you at any age. Some older adults may not believe there is a benefit in
quitting smoking. In fact, there are many benefits.
- If you quit smoking before age
50, you have half the risk of dying in the next 16 years compared with
people who continue to smoke. By age 54, your overall chance of dying
will be similar to that of people the same age who have never smoked.
- If you quit smoking, you also reduce your risk for cancer
of the esophagus, larynx, kidney, pancreas, and cervix as well as your
risk for chronic lung disease and heart disease.
- If you quit smoking before
you get pregnant, you can reduce your risk for premature delivery and
having a child with low birth weight.
- Buy a radon kit (available in
most hardware stores) that allows you to measure the radon levels in
your home. The home radon test is relatively easy to use and
inexpensive. Once a radon problem is corrected, the hazard is gone for
- Vitamin E /
Tocopherol - Based on solid evidence, taking
vitamin E supplements does not affect the risk of lung cancer.
- Beta Carotene
- Based on solid evidence, high-intensity smokers who take
pharmacological doses of beta carotene have an increased lung cancer
incidence and mortality that is associated with taking the supplement.
(NCAM) - A five-to-nine year safety and efficacy study tested
selenized yeast, which is about 85 percent selenomethionine, could
prevent nonmelanoma skin cancer. The study found that selenized yeast
significantly reduced all cancer deaths and decreased rates of lung,
prostate, and colorectal cancer.
