Hereditary Cancer Clinic

Access our eLearning module:

The Hereditary Cancer Clinic is part of the Eastern Ontario Regional Genetics Program and is located at CHEO. We specialize in the assessment of children, adults, and families with familial or hereditary forms of cancer predisposition. We offer genetic counselling, and genetic testing services if indicated. Through partnership with the Ontario Breast Screening Program (OBSP) we also provide women with a personal or family history of breast and/or ovarian cancer a personalized breast cancer risk assessment.

Our goal is to identify individuals and families who may be at an increased risk of developing specific types of cancer and to inform them about the appropriate prevention and screening recommendations available.

Who are we?

Our services are provided by a team consisting of specialized genetic counsellors, geneticists and 2 dedicated administrative staff.

As of April 2018, Cancer Care Ontario (CCO) is permitted to collect personal health information (PHI) from CHEO and other health information custodians for the purpose of facilitating or improving the provision of healthcare.

What does this mean for me as it relates to my care?

Prior to this change, you would have been asked to sign a Release of Personal Health Information in order for your information to be sent to CCO. This means at your visit, you will not be asked to fill out an authorization for the Release of Personal Health Information as part of the Ontario Breast Screening Program (OBSP). Your information will automatically be submitted to CCO as part of facilitating or improving the provision of healthcare. This change in practice has been reviewed and approved by the Information and Privacy Commissioner of Ontario.
