Colon Cancer Screening

Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. Rectal cancer is cancer of the last several inches of the colon. Together, they are often referred to as colorectal cancers. Colorectal cancer is the third most common cancer in the United States, excluding skin cancers, and the third leading cause of cancer deathApproximately 150,000 people each year are diagnosed with colon cancer and an estimated 50,000 Americans die annually from this disease.  Signs and symptoms of colon cancer can include:

  • A change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool for more than a few  weeks
  • Rectal bleeding or blood in your stool
  • Persistent abdominal discomfort, such as cramps, gas or pain
  • A feeling that your bowel doesn't empty completely
  • Unexplained weakness, fatigue or weight loss

Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they will likely vary, depending on the cancer's size and location in your large intestine.

Most cases of colon cancer begin as small growths called polyps. Over time some of these polyps grow to become colon cancers.  Polyps may be small and produce few, if any, symptoms. For this reason, doctors recommend regular screening tests to help prevent colon cancer by identifying and removing polyps before they become colon cancer.

National guidelines generally recommend colon cancer screenings beginning at age 50. You may need earlier screening if you have other risk factors, such as a family history of colon cancer or colon polyps, or a personal history of inflammatory bowel disease. The best time to get screened is before any symptoms appear.
Colon cancer is treatable if detected early, and can be prevented if colon polyps are removed during a colonoscopy before they turn into cancer.

Dr. Renny is an expert in colonoscopy and colorectal cancer screening. He has performed thousands of colonoscopies and is dedicated to maintaining a high level of quality in performing the procedure.  In a 2009 review of 320 consecutive colonoscopies Dr. Renny’s performance exceeded recommended 
national quality indicators.
