Letters to the Public About Cancer Screening

We mail letters to women turning 50 inviting them to get screened for breast cancer through the Ontario Breast Screening Program. Women between ages 51 and 73 who have not been screened in at least 3 years also receive a letter inviting them to get screened. 

In addition, we send letters to women ages 50 to 74 reminding them when it is time to return (recall) for screening and informing them of their results, if they are normal. Ontario Breast Screening Program sites continue to inform women of their results if they are abnormal.

Results Notifications

After screening tests are analyzed, participating labs and screening centres inform your doctor and Cancer Care Ontario about your results. We notify you of your test results in the following ways:

• Normal result – We notify all participants (with or without family doctors) about normal results by mail. The letter tells you that your result is normal and advises you when to get screened again, unless there is a change in your family history of cancer or you notice possible symptoms of cancer (in both cases you are advised to see your doctor).
• Abnormal result (participants with a doctor) — Your doctor will inform you about your abnormal result and provide you with next steps. We also send letters to you to tell you that your result is abnormal and advise you to see your doctor for follow-up if you
• Abnormal result (participants without a doctor) — We will contact you by mail and telephone to make sure you are referred to a doctor, who will then provide you with next steps.
• Unsatisfactory result – We notify you if the laboratory rejects your Pap test or fecal occult blood test or the result could not be read; in both cases, a retest is needed. For colorectal screening, you will be advised to contact your doctor to get another kit. If you don’t have a doctor, we advise you to contact Telehealth Ontario to get another kit. For cervical screening, you will be advised to contact your doctor, nurse practitioner or clinic to arrange for another Pap test.

Recall Notifications

After a normal test, we send recall letters to eligible average risk participants reminding them to re-screen in 2 years for breast and colorectal cancer, and 3 years for cervical cancer.

Reminder Letters

We also send reminder letters to participants who haven’t responded after receiving certain letters.
