Colorectal cancer is the second leading cause of death from cancer, and the third most common cancer overall. Men and women aging 50 or older are at almost equal risk of developing colorectal cancer. Those who have a personal or family history of colorectal cancer or polyps are at higher risk of developing the disease. Anyone who has a long-term personal history of inflammatory bowel disease (Ulcerative Colitis or Crohn’s Disease) also is at higher risk. The other disorder is Hereditary Non-Polyposis Colorectal Cancer (HNPCC). In this syndrome, cancers also occur early and develop from polyps. The disease also can present at a later age.
What Causes Colorectal Cancer ?
The exact causes of colorectal cancer are unknown, but the disease appears to be caused by both inherited (genetic) and lifestyle factors. Lifestyle factors – such as cigarette smoking, lack of physical exercise, and obesity – may increase the risk of developing the disease.
Colorectal cancer can be associated with blood in your stools, narrower than normal stools, unexplained abdominal pain, unexplained change in bowel habits, unexplained anemia or unexplained weight loss. It is also important to remember that colon cancer may not be associated with any symptoms, which is why early detection through screening is so important. The most common causes of bleeding from the rectum and anus are hemorrhoids and anal fissures or tears, which are usually easily treated. Some less common causes are infections of the colon (infectious diarrhoea), inflammatory bowel disease (ulcerative colitis or Crohn’s colitis), colonic diverticula, or abnormal blood vessels (arteriovenous malformations or angiodysplasia). Colonic obstruction, or blockage of the passing of stool and gas through the colon, is a late symptom of colon cancer.
Colorectal cancer screening should be a part of routine healthcare for people starting at the age of 50. People at higher risk for colon cancer should be screened earlier. Several screening options exist. These include the fecal occult blood test (FOBT), flexible sigmoidoscopy, double contrast barium enema, and colonoscopy. Colonoscopy is considered the gold standard for colorectal cancer screening should be done by endoscopist only.
Polyps are mushroom-like growths that form when cells lining the colon grow, divide and reproduce in an unhealthy, disorderly way. Polyps can become cancerous over time. Colorectal cancer can occur without polyps
