Colon Cancer Q & A

What causes colon cancer?

Most colon cancers begin as noncancerous polyps that develop in the lining of your colon (large intestine) or rectum. Polyps always begin as noncancerous growths. Over the years, however, their cellular DNA can change, making the cells grow abnormally and turn into cancer.

What symptoms develop due to colon cancer?

Colon cancer doesn’t cause symptoms at an early stage. As the tumor gets larger or spreads, you experience symptoms such as:

  • Change in bowel habits
  • Bright red blood in your stool
  • Dark, tarry stool
  • Abdominal pain
  • Feeling full or bloated
  • Unexplained weight loss
  • Fatigue

A change in your bowel habits could appear as diarrhea, constipation, narrow stools, or a change in stool consistency.

What increases my risk for colon cancer?

Age is one of the top risk factors because colon cancer grows slowly. As a result, the older you get, the more likely you are to develop cancer.

Your chance of colon cancer is also higher if you meet any of the following risk factors.

  • History of colon polyps
  • Family or personal history of colon cancer
  • Inflammatory bowel disease
  • Cigarette smoker
  • Inactive lifestyle
  • Overweight and obesity
  • Diet high in red meat and processed meat

Heavy alcohol use is also associated with a higher risk of colon cancer.

Can I prevent colon cancer?

Yes, colon cancer is largely preventable. Changing your lifestyle factors lowers your risk. Getting a colonoscopy is essential because it allows your doctor to find and remove polyps before they have time to turn into cancer. 

During a colonoscopy, your doctor guides a narrow tube containing lighting and a camera through your rectum and to the end of your large intestine. As your doctor slowly withdraws the colonoscope, they use tools inserted through the scope to remove polyps.

How do you treat colon cancer?

In the early stages, your doctor at Houston Regional Gastroenterology may entirely remove the cancer during a colonoscopy. Otherwise, your doctor performs surgery to remove the affected portion of your colon, along with its associated lymph nodes.

Whenever possible, your doctor performs minimally invasive laparoscopic surgery. Some patients, however, require open surgery. 

Advanced cases of colon cancer may need chemotherapy alone or with radiation therapy. These treatments may occur before surgery to shrink the tumor or after your surgery to eliminate any remaining cancer cells.
