WHAT IS LUNG CANCER?
Cancer is a disease with growth of cells that are not normal
and they crowd out and destroy healthy tissue. Lung cancer is the most
common cancer-related cause of death among men and women. It is the second
most commonly occurring cancer among men and women. It has been estimated
that there will be 169,500 new cases of lung cancer in the U.S. in 2001
alone. It is possible for cancer cells that begin
in other organs to spread to the lungs.
WHAT CAUSES LUNG CANCER?
Smoking is the number one cause of lung cancer. It is thought
that more than 80% of lung cancers result from smoking. Cigarette smoke
contains more than 4,000 different chemicals. Many of these chemicals
are proven to cause cancer.
Many of these chemicals also affect the nonsmoker breathing
in "secondhand" or sidestream smoke,* making "passive smoking" another
cause of lung cancer.
If you smoke, you are much more likely to develop the disease;
men who smoke are 22 times more likely to develop lung cancer, while women
who smoke are 12 times more likely to develop lung cancer.
The more you smoke and the longer you smoke, the greater
your chance of having lung cancer. But if you stop smoking, the chances
of having lung cancer decreases every year as abnormal cells are replaced
by normal cells.
In addition, quitting smoking decreases your chances of
developing diseases caused from smoking, like, heart disease and stroke,
and emphysema and chronic bronchitis.
Radon, by its own action and by its action with cigarette
smoking, is the second leading cause of lung cancer in the U.S. today.
Radon is a gas that is found in the earth's rock and soil and is formed
by the natural breakdown of radium, which is a product of decaying uranium.
It is estimated that 15,000 Americans die each year from lung cancer caused
by radon.
Radon problems have been identified in every state. It
is estimated that nearly 1 out of every 15 homes in the U.S. has indoor
radon levels at or above the recommended level. Radon can be a problem
in schools and workplaces, too.
Because radon cannot be seen and it does not have any odor
or smell to it, the only way to find out if you are being exposed to the
gas is by checking the radon levels.
Another leading cause of lung cancer is on-the-job exposure
to asbestos, uranium, arsenic, certain petroleum products, and others.
There are many types of jobs that may put you increase
your chances for cancer causing situations. Some examples are working
with certain types of insulation, working with coke ovens, and repairing
brakes.
WHO GETS LUNG CANCER?
Lung cancer occurs most often in people over fifty who
have been smoking cigarettes for a long time. The incidence of lung cancer
in women as a whole has climbed at an alarming rate, and these increases
are related to the increases in the number of women who have smoked. In
1987, lung cancer, was higher than breast cancer for the first time as
the leading cause of cancer deaths in women.
It has been estimated that there will be 169,500 new cases
of lung cancer in the U.S. in 2001; 90,700 among men and 78,800 among
women. The lung cancer rates for both black and white males decreases
between 1984 and 1998, the rate in black males is almost 48 percent higher
than the rate in white males.
The rates in both black and white women has risen. Between
1984 and 1998, the rates have increased 25 percent overall, 28.7 percent
in white women and 20.7 percent in black women.
WHAT ARE
THE SYMPTOMS OF LUNG CANCER?
In the early stages and even later, lung cancer is usually
silent. When symptoms appear, the cancer is often advanced. Symptoms of
lung cancer include:
• Constant cough
• Hoarseness
• Coughing up blood or rusty-colored sputum
• Weight loss & loss of appetite
• Shortness of breath
• Fever without a known reason
• Wheezing
• Infections such as bronchitis & pneumonia that keep
coming back
• Chest pain
These conditions are also the same for many other lung
problems; so, when they occur, they need to be checked by your doctor.
Don't wait.
HOW IS LUNG
CANCER DETECTED?
When a person goes for an examination, his or her doctor
will gather information and examine you. If you are coughing up sputum,
the sputum may be examined for cancer cells.
The doctor will order a chest X-ray or specialized X-ray
such as the CAT scan, which help to locate any abnormal spots in the lungs.
The doctor may do a bronchoscopy to look inside the tubes of your lungs
(A bronchoscope is a small tube inserted through the nose or mouth, down
the throat, into the bronchial tubes.). During this procedure the doctor
may also do a biopsy or get sample of lung tissue and cells to examine
under a microscope to determine if cancer is present.
HOW IS LUNG
CANCER TREATED?
- Surgery may cure lung cancer. It is used in limited
stages of the disease.
Radiation therapy is a form of high energy X-rays.
It is used:
• In combination with chemotherapy (medication) and sometimes
with surgery
• To offer relief from pain or for the relief of blockage
of the airways
- Chemotherapy is the use of drugs that are effective
against cancer cells.
It may be used:
• In combination with surgery
• In more advanced stages of the disease
• In all stages of small cell carcinoma
In addition, discoveries in the diagnosis and treatment
of lung cancer are being made.
HOW CAN LUNG CANCER
BE PREVENTED?
- If you are a smoker, STOP SMOKING. Your local American
Lung Association has books, videos, and group programs to help you quit
for good.
- If you are a nonsmoker, make sure that your rights
to a smoke-free environment are upheld.
- Strive for a smoke-free environment both at home and
at work.
- Test your home for radon if you live in an area known
to have high levels.
- Ask questions about your work area if you are exposed
to industrial dusts and fumes.
- Lung cancer is the leading cancer killer in the United
States and until there is a cure, the only way to defeat lung cancer
is to prevent it from ever happening.
