Lung Cancer
The lungs are the organs that
help us breathe. They help to
give oxygen to all the cells in
the body.
Cancer cells are abnormal cells.
Cancer cells grow and divide
more quickly than healthy
cells. Some cancer cells may
form growths called tumors.
Lung cancer occurs when cells
in the lung change to become
abnormal. Lung cancer cells
may travel through the blood or
lymph system to another area
or organ in the body. This is
called metastasis.

lung cancer if you:
