About the Condition

Colon cancer is cancer of the large intestine, also known as the colon. Rectal cancer is cancer in the last few inches of the colon. Colon cancer and rectal cancer together are known as colorectal cancer.

Colon cancer and rectal cancer typically develop slowly over several years. Most colorectal cancers begin as a polyp, which is an abnormal growth of cells in the colon. Removing colon polyps early may prevent them from becoming cancer. It is important to have a regular colon cancer screening to detect and remove colon polyps before they become cancerous. Colorectal cancer is highly treatable and often a curable cancer when localized.

Men and women are almost equally affected by colon cancer. African Americans and Hispanics are at higher risk for colon cancer and are more likely to be diagnosed in the more advanced stages of cancer.

Hereditary colorectal cancer is passed between generations through an inherited mutated gene that causes cancer to develop at an early age. Although the majority of colorectal cancer cases are not hereditary, a strong family history of colorectal cancer on one side of the family greatly increases the risk of developing colorectal cancer.

Symptoms & Diagnostic Process

Since colorectal cancer seldom has symptoms, it is important to have a regular colon cancer screening to detect and remove any colon polyps.

When colorectal cancer symptoms do occur, they can be similar to other digestive diseases and include:

  • Change in bowel habits
  • Rectal bleeding
  • Blood in stool
  • Cramps
  • Gas
  • Pain
  • A sense the bowel has not emptied completely
  • Fatigue
  • Weight loss

Treatment Options

Colon polyps often are removed during a colonoscopy. However, if the polyps are too large to remove during a colonoscopy, they are removed through laparoscopic surgery. In advanced stages of cancer in which the cancer has moved through the colon wall, part of the colon may need to be removed. Colon cancer treatment options then may include a combination of chemotherapy, radiation, or targeted drug therapy.
