Colon Cancer Screening

​​

Why do we screen?

Colon cancer is the second most common cancer in Ontario, it is also the second leading cause of cancer related deaths. It is estimated that nearly 12,000 patients will be diagnosed of colon cancer in Ontario, and 3000 will die. When colorectal cancer is caught early, 9/10 patients can be cured.

​

How do we screen?

​

1. FIT (Fecal Immunohistochemistry Test)

Available to all average risk patients from 50-74, and is repeated every 2 years if it is normal

​

2. Colonoscopy

Recommended for anyone at high risk of colon cancer (i.e. first-degree relative with colon cancer) and screening starts at 50 years old (or 10 years prior to age of diagnosis of the relative). 

Repeat screening is dependent on findings. Details can be found at Cancer Care Ontario.

Don't Smoke - As with many cancers, smoking increases the risk of colon cancer. Current estimates range from 20-60% based on the study

Limit Red Meat - Eating 100 grams of red meat per day is associated with a 20% increase in colon cancer

Live a healthy lifestyle - A diet rich in fibre, combined with regular exercise can help to lower your risks of colon cancer.
