Who Should Be Concerned for Colon Cancer?

Colon cancer, also known as colorectal cancer, is a type of cancer that affects the large intestine (colon) and rectum. While anyone can develop colon cancer, certain risk factors can increase your susceptibility.

Age

• Over 50: The risk of colon cancer increases significantly after the age of 50.

• Family history: A family history of colon cancer, particularly in a first-degree relative (parent, sibling, or child), significantly increases your risk.

• Personal history of polyps: Adenomatous polyps, a type of benign growth in the colon, can develop into colon cancer. If you have a history of polyps, your risk of colon cancer is higher.

• Inflammatory bowel disease (IBD): People with IBD, such as ulcerative colitis or Crohn's disease, have an increased risk of colon cancer.

• Genetics: Certain genetic conditions, such as familial adenomatous polyposis (FAP) and hereditary non-polyposis colon cancer (HNPCC), can significantly increase the risk of colon cancer.

• Lifestyle factors: Certain lifestyle choices can also increase the risk of colon cancer, including:

• Diet: A diet high in red meat and processed meats and low in fibre has been linked to an increased risk of colon cancer.

• Obesity: Being overweight or obese can increase your risk.

• Smoking: Smoking is a known risk factor for colon cancer.

• Physical inactivity: Lack of physical activity can increase the risk of colon cancer.

• Alcohol consumption: Excessive alcohol consumption may also increase the risk.

Screening for Colon Cancer

If you have any of the risk factors mentioned above, it's important to talk to your doctor about colon cancer screening. Regular screening tests, such as a colonoscopy, can help detect colon cancer early, when it is most treatable.

• Age 50 and older: If you have no risk factors, the recommended age for starting colon cancer screening is 50.

• Increased risk: If you have a family history of colon cancer or other risk factors, you may need to start screening earlier.

It's important to remember that while these factors can increase your risk of colon cancer, they do not guarantee that you will develop the disease. Many people with risk factors never develop colon cancer. Regular screening and a healthy lifestyle can help reduce your risk.

If you have any concerns about your risk of colon cancer, talk to your colorectal doctor. They can provide personalised advice and recommendations based on your individual circumstances.
