It’s important that you talk to a health care provider if you are experiencing symptoms of colon cancer. Cancer screening is intended for people who are not experiencing symptoms of cancer. A healthcare provider will determine the best course of action based on your personal situation.
Colon cancer refers to both colon and rectal cancers, which are very similar in terms of risk factors, diagnosis and prognosis. Because most people in the public refer to both as colon cancer, the Canadian Cancer Society, Ontario division has chosen to refer to both as colon cancer.
If you are over 50 years old and don’t have a family doctor, call Telehealth to talk to a registered nurse about getting the kit at 1-866-797-0000 or TTY : 1-866-797-0007
You should collect the stool samples on three different days. The samples can be taken at different times so they may be less than 24 hours apart. You may miss a day collecting your samples; however, it is important that your third sample is collected within 10 days of the first sample.
The samples should be collected on different days. If you have more than one bowel movement in the same day you should wait until the next day to collect your next sample.
You should not do the test if you are experiencing any symptoms of colon cancer, including if there is blood in your stool. If you are experiencing symptoms of colon cancer, it’s important that you speak to a healthcare provider.
If you are currently menstruating, have blood in your urine, or are bleeding from hemorrhoids or dental work, you should wait to do the test until you have stopped bleeding for at least three days.
An at home stool test, also known as the Fecal Occult Blood Test (FOBT) is the recommended screening test for colon cancer for people of average risk who are 50 or over. It’s safe, non-invasive and has been identified as the best method to detect colon cancer in people who are at average risk with no symptoms of colon cancer. If you are at a higher risk of colon cancer, talk to a health care provider about which test is right for you.
Many lesbian, bisexual and queer women prefer natural and holistic ways of taking proactive care of our health. It’s wonderful to take care of your health in the ways that work for you. While there may be many natural ways that we can take care of our colon health, the most reliable method of finding colorectal cancer early for those at average risk is testing the stool for occult (hidden) blood.
Colon cancer screening tests are generally very safe and have minimal risk however the FOBT isn’t perfect. There is a small chance that the FOBT will not detect blood in the stool, because a polyp may not be bleeding at the time you take the test. This is why it is important to get screened every two years from age 50 onwards.
FIT (or iFOBT) is a newer type of FOBT that uses specific antibodies for human blood to find traces of blood in the stool. FIT is being used by some, but not all, screening programs in Canada. FIT is currently not being used in Ontario.
Yes. Aside from diagnosing other problems, such as Crohn’s disease, the colonoscopy will have checked for polyps that are indicative of colon cancer.
Adenomatous polyps (adenomas) are a type of polyps that can sometimes become cancerous and takes, on average, ten years to develop into an invasive colon cancer. The incidence of adenomas increases with age.
Familial adenomatous polyposis is an uncommon inherited condition that causes hundreds to thousands of polyps to develop on the lining of the colon and/or rectum and greatly increases a person’s risk of developing colon cancer. If left untreated, almost all people with FAP will develop colon cancer. FAP accounts for 1% of colon cancers and can be identified through family history and genetic testing.
Hereditary non-polyposis colon cancer is an uncommon inherited condition that causes a large number of polyps to develop, although less than those with FAP. People with HNPCC have a 70-80% lifetime risk of developing colon cancer. HNPCC accounts for 3-5% of all colon cancers and be identified through family history and genetic testing.

The biggest benefit of a colonoscopy is, of course, that it can find cancer, either before it starts or at its early stages, and save your life. But colonoscopies can have risks associated with them as well. Some of those side effects can include:
Some more uncommon complications could include:
While it can be scary to think of these possible risks and side effects of getting a colonoscopy, it’s important to remember that the risk is actually quite low.
The research on smoked fish is inconsistent. We do know that smoking exposes meat or fish to the smoke of a wood or charcoal fire. The foods absorb large amounts of the tar that comes off the smoke. These tars may contain cancer-causing compounds.
It is often difficult to determine the risk of cancer in studies because cured and smoked foods are often salted and cured foods like bacon may also be cooked at a high temperature. All of these may be factors in increasing cancer risk.
Drinking more than one drink a day even if you have not drank alcohol in the previous few days is not advised. The scientific evidence related to alcohol drinking and an increased risk of cancer continues to grow. The risk of developing cancer increases with the amount of alcohol a person drinks. For example, drinking about 3.5 drinks a day can increase the risk of developing cancer of the colon and breast by 1.5 times. For more information, click here.
Jews of Eastern European descent (Ashkenazi Jews) are at increased risk of developing colon cancer because this group tends to have a specific mutation in the APC gene that increases the risk of colon cancer. This genetic mutation is not common among other ethnic groups.
Anal cancer is often confused with colon cancer. Colon cancer begins when cells in the lining of the colon or rectum change and become abnormal. Abnormal cells can multiply and form small, non-cancerous growths called polyps. Anal cancer occurs in the anal canal. A different type of cell lines the anal canal and thus, it is a different type of cancer. Anal cancer spreads slower that colon cancer. Colon cancer is much more common that anal cancer. There are currently no clear guidelines on anal cancer screening for lesbian, bisexual and queer women in Ontario, but if anal cancer is detected and treated early, the chances of successful treatment are better.
