Screen for cancer
Cancer screening is testing done on people who may be at risk of getting cancer, but who have no symptoms and generally feel fine. Cancer screening tests are not meant to diagnose cancer — instead, they help determine which people are more likely to have cancer or develop cancer in the future. In Ontario there are 4 free cancer screening programs.
Free cancer screening
Breast cancer
The Ontario Breast Screening Program is a province-wide screening program designed to reduce breast cancer deaths through regular screening.
Colorectal cancer
ColonCancerCheck is a province-wide screening program designed to reduce colorectal cancer deaths through regular screening.
Cervical screening
The Ontario Cervical Screening Program is a province-wide screening program designed to reduce the risk of getting or dying from cervical cancer through regular screening.
Lung cancer
The Ontario Lung Screening Program is designed to reduce lung cancer deaths through regular screening of people at high risk of getting lung cancer.

Cancer screening tests
Your health care provider can recommend several tests to screen for different cancer types. Depending on what you are at risk for, your health care provider may recommend that you complete a:
- fecal immunochemical test (colon cancer)
- mammogram (breast cancer)
- cervical screening test (cervical cancer)
- low-dose computed tomography (CT) scan (lung cancer)
Diagnosis
An abnormal screening test result does not mean that you have cancer but it does mean that you may need more tests to rule out or confirm a cancer diagnosis and inform the next steps in your care.
Treatment
The course of your treatment will be determined not only by the type and stage of cancer, but also by what treatments and services you choose.
Cancer statistics
Relative to their peers in the general population (of the same age and sex), survival rates among people with cancer in Ontario have improved over time for all cancers combined, though there is variation in survival by cancer type.
- Close to 90% or more of people with breast, prostate, thyroid, or testicular cancers, or melanoma, diagnosed between 2016 to 2020, are living at least 5 years after diagnosis.
- Nearly 75% of people with cervical cancer and 65% of people with colorectal cancer, diagnosed between 2016 to 2020, are living at least 5 years after diagnosis.
- Less than 25% of people with pancreatic, esophagus, or liver cancers, diagnosed between 2016 to 2020, are living at least 5 years after diagnosis.
- For all cancers combined, cancer mortality rates (adjusted for age) in the province have decreased from 1986 to 2020.
- At the end of 2020, the number of Ontarians living with a cancer diagnosis within the previous 10 years was over 419,000 — this is an over 20% increase from a decade earlier.
Tips to prevent cancer
To help reduce your chance of getting cancer, as well as many other diseases, you should:
- eat a well-balanced diet (lots of fruit and vegetables and high-fibre, lower-fat foods)
- maintain a healthy body weight
- limit alcohol intake
- be physically active
- live smoke-free (for example, consider quitting smoking cigarettes)
- avoid direct sunlight and wear sunscreen when outdoors
Tell your doctor about:
- any close family members who have had cancer
- any unusual swellings or lumps
- any changes in your overall health
Your doctor can determine if you should begin screening.
