Colorectal Cancer - Cause
Most cases begin as
polyps , which are small growths inside the colon or
Colon polyps are very common. Some polyps can turn into cancer. But doctors can't tell ahead of time which polyps will turn
into cancer. This is why people age 50 and older need regular tests to find out if
they have any polyps and then have them removed.
Some people who are
younger than 50 need regular tests if their medical history puts them at
increased risk for colorectal cancer.
