Lung Cancer
Lung cancer starts in the lining of the
bronchi in the lungs and develops over many years. The lungs are
two sponge-like organs that bring oxygen in and get rid of carbon dioxide.
The trachea (windpipe) brings air into the lungs and is
then divided into tubes called bronchi. The bronchi then
divide into smaller branches called bronchioles. Tiny air
sacs, alveoli, are at the end of the bronchioles. Lung cancer
is a life-threatening disease because it usually spreads
to other parts of the body before X-rays detect it.
Two major types of lung cancer
- Small cell lung cancer (SCLC) - The cells are small and
can multiply quickly to form large tumors.These cells
can also spread to lymph nodes and other parts of the
body. Small cell lung cancer is almost always linked to
smoking.
- Non-small cell lung cancer (NSCLC) - Squamous cell carcinoma,
Adenocarcinoma and Large-Cell undifferentiated carcinoma
make up the NSCLS.
Signs and symptoms
- Persistent
cough
- Sputum
streaked with blood
- Chest
pain
- Recurring
pneumonia or bronchitis
Treatment options for lung cancer include:
For most cancers that have not spread, surgery is the treatment
of choice. However, because most lung cancers have spread
by the time they are discovered, radiation therapy and chemotherapy
are often used in combination with surgery. For small cell
lung cancer, chemotherapy combined with radiation is the
treatment of choice.
