Catch colon cancer early

Colorectal cancer is the third-leading cause of cancer-related deaths in the United States. However, with proper screening, colon and rectal cancer can be prevented.  Colorectal cancer often starts in the large intestine (colon and rectum) as a polyp, a small growth on the inner lining of the colon. Symptoms can be nonspecific. Common abdominal ailments or a change in bowel habits are common occurrences, but don’t always mean you have colorectal cancer.

According to the American Cancer Society, the recommended age to start regular colorectal screening is 45 unless you have a family history of colorectal cancer or predisposing, inherited syndrome.

Other factors that may contribute to colonic polyps include inflammatory bowel disease, smoking, obesity, drinking alcohol, lack of exercise and eating a diet rich in fats.

colonoscopy is the best way to detect colorectal cancer. This examines the entire large intestine and detects the presence of polyps that could be or possibly become cancerous. When discovered early, colon cancer is highly treatable, so colonoscopy screening is crucial.

Screening is recommended for patients who have the following symptoms:

  • Blood in the stool
  • Rectal bleeding
  • Change in bowel habits or lower abdominal cramping
  • Family history of colon cancer and over age 40
  • Over age 45 (even without symptoms)

The human digestive system is a complex network of tubes and specialized organs. Its essential function is to digest food, extract nutrients from food to nourish the body, and dispose of waste. The digestive system is always at work, so it’s not uncommon for problems to occur. In fact, between 60 and 70 million people suffer from digestive diseases.
