Lung Cancer
Prevention
The
best known way to prevent lung cancer is to not smoke. If
you already smoke, quitting now can reduce your risk — even
if you've smoked for years.
These
measures also can help prevent lung cancer:
* Avoid secondhand smoke. Breathing the smoke of others
can be just as damaging as smoking is.
* Test for radon. Have the radon levels in your home checked,
especially if you live in an area where radon is known to
be a problem.
* Avoid carcinogens. Take precautions to protect yourself
from exposure to toxic chemicals such as vinyl chloride,
nickel chromates and coal products. Your risk of lung damage
from these carcinogens increases if you also smoke.
* Eat a healthy diet. Some studies have documented the relationship
between food and cancer. The American Cancer Society recommends
eating five to six servings of fruits and vegetables every
day. In the case of lung cancer, certain foods seem to be
especially protective. For example, a large study in China,
where smoking rates are high, found that certain chemicals
in cruciferous vegetables such as broccoli, cabbage and
bok choy appeared to lower the risk of lung cancer. Other
protective chemicals called cumestrans are found in beans,
peas, spinach and sprouts. Isoflavones, the most common
anticancer chemicals, occur in a wide range of foods, including
soybeans, chickpeas and yams. Other studies have found a
connection between consumption of large amounts of fresh
fish — though not dried or salted fish — and a reduced rate
of lung cancer. The American Cancer Society says more research
is needed to establish a clear link, however.

Lung
cancer is a cancer of the lungs characterized by the presence
of malignant tumours. Most commonly it is bronchogenic carcinoma
(about 90%). Lung cancer is one of the most lethal of cancers
worldwide, causing up to 3 million deaths annually. Only
one in ten patients diagnosed with this disease will survive
the next five years. Although lung cancer was previously
an illness that affected predominately men, the lung cancer
rate for women has been increasing in the last few decades,
which has been attributed to the rising ratio of female
to male smokers.
Current
research indicates that the factor with the greatest impact
on risk of lung cancer is long-term exposure to inhaled
carcinogens. The most common means of such exposure is tobacco
smoke.
Treatment
and prognosis depend upon the histological type of cancer
and the stage (degree of spread). Possible treatment modalities
include surgery, chemotherapy, and/or radiotherapy.
