Types of Inherited Colon Cancer

Legg inn av dgpvgjqajtun@yahoo.com » 26 nov 2007 13:02:02

Colon cancer is becoming more common. There will be around 125,000 new
cases diagnosed in America this year. Many of these cases are in
people more than 50 years old and are random. A small percentage,
approximately 10%, however are not random, they have an inherited form
of colon cancer. This could be caused by four different hereditary
conditions, hereditary non-polyposis colon cancer, familial
adenomatous polyposis, juvenile polyposis (this may also be
nonhereditary) and Peutz-Jegher's syndrome.
Colon cancer is caused by damage to the genes in your colon cells.
These damages can cause the cells to grow unrestricted. This
unrestricted growth becomes a polyp, which will become cancerous if
it's not removed. Usually it takes a long time for polyps to develop
and even longer to become cancerous. That's why colon cancer is rare
in people less than 50 years old. The cases in people less than 50 are
frequently caused by an inherited condition.
Inherited colon cancers are difficult to accurately diagnose. It is
first considered when a person has a strong family history of colon
cancer and the affected family members are from separate generations.
For example - a man has two uncles and a cousin that have been
diagnosed, this would be a strong family history. With a bit of
research into that patient's family tree, many more cases of colon
cancer may be found and documented....
