Metastasis (muh-tas-tuh-sus) is one of the major causes of death
from cancer. It refers to the development of secondary tumors at
different locations in the body from the original cancer.
Eventually, these tumors interfere with vital body functions,
and if they don't respond to treatment, will prove fatal. Most
metastases (muh-tas-tuh-sees) form by cancer cells dividing and
spreading through the capillaries and veins. They also spread
through the lymphatic (lim-fa-tick) system and through the
body's cavities. The most common areas for metastasis to occur
are in the bones, lungs, liver, and central nervous system. Once
a cancer has spread to other parts of the body, it is much
harder to treat successfully. That's why it is so important to
have regular check-ups and cancer screenings. Early detection is
the best protection. For more information on the spread of
cancer, contact a healthcare professional.
