Facts About Lung Cancer
How common is lung cancer in women?
Lung cancer is the largest single cause of cancer deaths in
the United States. For years, men were at higher risk for lung cancer because
of higher smoking rates. However, with more women smoking, lung cancer
surpassed breast cancer in 1987 as the leading cause of cancer deaths among
women. Over the last two decades, lung cancer deaths have increased 150 percent
in women, compared to an increase of about 20 percent in men. In fact, with all
outside factors being equal, women have a greater risk of developing lung
cancer than men. Several studies have suggested that estrogen may help lung
cancers to grow, increasing the risk of lung cancer developing in women.
What causes lung cancer?
Smoking is by far the leading risk factor for lung cancer.
Tobacco smoke causes more than eight out of 10 cases of lung cancer. The longer
a person has been smoking and the more packs per day smoked, the greater the
risk. If a person stops smoking before lung cancer develops, the lung tissue
will slowly return to normal. Cigar and pipe smoking are almost as likely to
cause lung cancer as is cigarette smoking.
People who do not smoke but who breathe the smoke of others
(second-hand smoke) also have a higher risk of lung cancer. Second-hand smoke
is the third leading cause of preventable death in America, yet nearly half of
all non-smoking Americans are still regularly exposed to it. Non-smokers
exposed to second-hand smoke at home or work, increase their risk of developing
lung cancer by 20 percent to 30 percent.
Asbestos is another risk factor. People who work with
asbestos have a higher risk of getting lung cancer. If they also smoke, the
risk is greatly increased. Arsenic and radon, as well as other cancer-causing
agents in the workplace, are also risk factors. Other factors that increase a
person’s risk include having had radiation therapy to the lung; personal and
family history; diet; and air pollution.
What is the current treatment for lung cancer?
The best way to avoid death from lung cancer is never to
smoke or to stop smoking. Once lung cancer is diagnosed, there are several
treatment options, including radiation, various chemotherapies and surgery.
Survival rates have improved for non-small cell lung cancer because of advances
in combination radiation/chemotherapy treatment. However, small cell lung
cancer (most often found in people who smoke cigarettes) is still very
difficult to treat. Small cell is the most aggressive of lung cancers, and many
patients have advanced disease by the time it is diagnosed. Small cell lung
cancer is responsive to both chemotherapy and radiation, yet nearly all these
patients eventually relapse and need additional treatment.
There is a clear need for more effective treatments for lung
cancer. New advances in research have recently led to new drugs that can
protect normal cells from being destroyed from chemotherapy.
Early detection remains the key to successful therapy. If
you have a history of chronic coughing, coughing up blood, chest pain,
shortness of breath, hoarseness or wheezing, on-going problems with bronchitis
or pneumonia, swelling of the neck and face, loss of appetite or weight loss,
or fatigue, you should be evaluated by your physician as soon as possible. Lung
cancer is not the only smoking-related cause of death in women. The World
Health Organization states that at least 25 percent of women smokers will die
of smoking-related disease such as cardiovascular disease and chronic
obstructive pulmonary disease (COPD).
How can I prevent lung cancer?
The best way to prevent lung cancer is to avoid smoking. If
you currently smoke, ask your health care provider to assist you in finding
resources to help you quit smoking. It is also important to try to avoid
second-hand tobacco smoke, radon, asbestos and pollution, which can increase a
person's risk of developing lung cancer. Controlling other lung diseases, such
as tuberculosis can help prevent lung cancer, since there is evidence that lung
cancer tends to develop in scarred areas of the lung. Finally, eating a good
diet with lots of fruits and vegetables also may help prevent lung cancer.
