Smoking and the Possibilities of Lung Cancer


------------------------------------------------------------------------------

QUESTION:  Your column and its many warnings about the dangers of smoking have
finally gotten to me.  I am still worried about the possibilities of lung
cancer, however and would appreciate a better understanding of the disease and
its treatment.  Would you please oblige?

------------------------------------------------------------------------------

ANSWER:  Congratulations, you've taken the single best step in preventing lung
cancer.
     Lung cancer is among the leading causes of cancer death in the United
States for both men and women, and cigarette smoking is by far the most common
cause.  Unfortunately, lung cancer usually remains undetected until a patient
develops symptoms, and by that time, it is pretty well advanced.
     Symptoms of lung cancer include coughing (the most common one), shortness
of breath, dull chest pain, and coughing up blood.  If you have any of these
symptoms, see your physician without delay.
     Cancer is the rapid growth of what were once normal body cells.  Lung
cancer can take the form of a tumor (a lump of cancerous tissue) or may be
spread out with cancerous cells strewn among normal ones.  A benign tumor
contrasted with a cancer (or malignant growth) is one that essentially keeps
to itself, but it may cause problems as it takes up space.  A cancerous growth
sends out cancer cells that grow elsewhere in the body in a process known as
"metastasis" and is one of the reason early diagnosis and treatment is so
important.
     There are many varieties of lung cancer and treatment for each varies,
depending on where in the lung the tumor is and how advanced it is.  The
primary treatments for lung cancer are surgery, radiation and chemotherapy
drugs.
     Surgery is used to remove as much cancerous tissue as possible, but if
the patient is not in good enough shape to withstand an operation, surgery may
not be an option.  Radiation therapy may be also needed after surgery.
Radiation kills fast-growing cells, such as cancer cells, but has the unwanted
effect of killing some healthy cells also.  Radiation is used for patients who
have a disseminated type of cancer, (one that is widely spread) since surgery
simple can't get at and remove all these malignant cells.  It can also be used
after surgery, to destroy any cancer cells that may remain.
     The use of anticancer drugs, or chemotherapy, is usually reserved for a
type of lung cancer known as small-cell lung cancer, which is a type that
disseminates quickly and is usually well-advanced when it is detected.
Anticancer drugs act similarly to radiation, in that they kill fast-growing
cells.  This is why a side effect of both radiation and chemotherapy is hair
loss, since hair roots are cells that also grow quickly.  Because many lung
cancers are well-advanced by the time they are diagnosed, the percentages of
people with this diagnoses who survive more than five years after diagnosis is
certainly not as high as we all might wish for.  This is a distressing
situation, that demands that we come up with improved early detection systems
for lung cancer.  The secret to increased survival lies in early detection
techniques quickly followed by effective methods for treatment.  The intensive
campaign against smoking, which may annoy many uninformed people, must
continue, to stop a major cause of cancer in the United States from remaining
a hazard to life.
