are the symptoms of lung cancer?
Symptoms of lung cancer vary. If the cancer develops in the
trachea or bronchus, the patient may exhibit coughing due
to the irritation of the growth. This growth can bleed making
the patient cough up blood. As the tumor grows, the airway
becomes blocked causing shortness of breath. Repeated lung
infections and pneumonia are also seen in lung cancer cases.
If the tumor is located in the lung tissue itself, symptoms
are usually not noticed until it grows larger. Symptoms of
chest pain may be the first complaint of these patients.
symptoms may include:
-Abnormal chest x-ray
are the causes and risk factors for lung cancer?
Smoking remains the number one cause of lung cancer. The more
time and quantity the patient smokes, the greater the risk
for developing lung cancer. If a patient stops smoking, the
risk of developing lung cancer decreases each year as the
healthy cells in the lungs begin to replace the abnormal ones.
Second-hand smoke accounts for 30% of lung cancer cases diagnosed
in people who have never smoked.
causes of lung cancer are:
-Radon. Radon is now considered to be the second leading cause
of lung cancer in the United States.
-Certain petroleum products
is lung cancer diagnosed?
Unfortunately, lung cancer tends to produce no symptoms in
its early stages, so often it is not diagnosed until it has
become advanced. Symptoms of lung cancer also mimic many other
lung problems, so a patient who has any of these symptoms
should go see their physician. A medical history is taken
by the physician, including questions about any exposure to
hazardous substances. A physical exam is also performed by
the physician. Additional testing may include:
is lung cancer treated?
Treatment for lung cancer will be decided on several factors
-Type of lung cancer
-Extent of the tumor (whether it has spread)
are available, which may be used alone or in combination.
may also be eligible to participate in clinical trials or
research studies that look at new ways to treat lung cancer.
