đ When most people think about breast cancer risk, they think about family history. But as youâve seen in this carousel, thatâs only one piece of the puzzle.
Your age, breast density, reproductive history, previous breast biopsies, lifestyle, and family history all contribute to your overall risk.
Many of these factors can be combined using validated risk assessment tools to estimate your chance of developing breast cancer over the next 10 years and throughout your lifetime.
While these tools canât predict whether youâll develop breast cancer, they can help guide decisions about screening, prevention, and whether additional testing or genetic assessment may be appropriate.
Common breast cancer risk assessment tools used in Canada include:
â
TyrerâCuzick (IBIS) â One of the most comprehensive models. It incorporates family history, breast density (when available), reproductive history, benign breast disease, and other personal risk factors. It is commonly used in breast imaging clinics and high-risk programs.
â
CanRisk (BOADICEA) â Often used by genetics and hereditary cancer clinics. It estimates breast and ovarian cancer risk and can help determine whether genetic testing may be appropriate.
â
The Gail Model (Breast Cancer Risk Assessment Tool) â Primarily estimates risk for women without a strong family history. It is less comprehensive than TyrerâCuzick but may still be appropriate in some situations.
These tools are generally completed by your family physician, nurse practitioner, breast specialist, genetics clinic, or breast imaging clinic. If youâre unsure whether a formal risk assessment would benefit you, itâs worth starting the conversation.
