2. Lungs
The lungs are a pair of spongy, air-filled organs located on either side
of the chest (thorax). The trachea (windpipe) conducts inhaled air into
the lungs through its tubular branches, called bronchi. The bronchi
then divide into smaller and smaller branches (bronchioles), finally
becoming microscopic.
The bronchioles eventually end in
clusters of microscopic air sacs called
alveoli. In the alveoli, oxygen from
the air is absorbed into the blood.
Carbon dioxide, a waste product of
metabolism, travels from the blood
to the alveoli, where it can be
exhaled. Between the alveoli is a thin
layer of cells called the interstitial,
which contains blood vessels and
cells that help support the alveoli.
3. Lung Cancer
The two main types of lung cancer are non-small cell lung
cancer and small cell lung cancer. The types are based on
the way the cells look under a microscope. Non-small cell
lung cancer is much more common than small cell lung
cancer.
4. Causes of Lung Cancer
• Smoking and lung cancer
• Exposure to radon gas
• Exposure to certain chemicals
• Air pollution
• Previous lung disease
• A family history of lung cancer
• Past cancer treatment
• Previous smoking related cancers
• Lowered immunity
5. Lung Cancer Surgery
A surgical oncologist is a doctor who specializes in treating
cancer using surgery. For lung cancer, a thoracic surgeon is
specially trained to perform lung cancer surgery. The goal of
surgery is the complete removal of the lung tumor and the
nearby lymph nodes in the chest. The tumor must be removed
with a surrounding border or margin of normal lung tissue. A
“negative margin” means that when the pathologist examines
the lung, or piece of lung that has been removed by the
surgeon, no cancer was found in the healthy tissue
surrounding the tumor.
