The risk of developing colorectal cancer is related to bad alimentary habits, cigarette smoking, intestinal inflammatory disease, polyps, genetic factors, and aging. Of patients diagnosed with colorectal cancer, 90% are older than 50 with a median age of 64. Signs and symptoms of colorectal cancer include blood within the stool, a change of bowel movements, weight loss and fatigue.
Colorectal cancer screening involves tests that look for early signs of disease before any symptoms have developed to enable prevention and early diagnosis of disease. This leads to timely intervention and management of a treatable condition.
