DIAGNOSIS
The maturation of polyps of the colon as a rule precedes the situation of colon cancer by five or more years.

PROPHECY
Prognostication depends on the originate of the disease and the overall fettle of the patient. If diagnosed untimely, before the tumor has spread from the bowel, these treatments are uncommonly possessions, with with 90% of patients active five years after diagnosis.
