Some questions in this assessment may be personal or hard to answer. Answering these questions will help you get a more accurate estimate of your risk for breast cancer. We’ll start with some basic questions.
Based on your previous responses, there are no questions required in this section.
This tool was designed for people who have never had cancer. Because you’ve had cancer before, your risk of getting another cancer in the future is higher than someone who hasn’t been previously diagnosed.
We hope you’ll continue with the remaining questions to learn how other factors may affect your risk of developing breast cancer. But keep in mind that the results at the end are more accurate for people without a history of cancer.
Please note that the source of data used in this risk assessment is based on people who were assigned female at birth. Gender binary language (male, female, man, woman) may sometimes be used. It’s also important to note that the word "chest" is sometimes used when describing the breasts. Some people, including trans men, transmasculine people and nonbinary people, may prefer the term "chest". The term “breast” is still used to make sure the language is clear for everyone.
If your gender differs from your sex assigned at birth, your assessment results may not be accurate for you and you should talk with your doctor or nurse practitioner about your personal risk of breast cancer. Please continue to fill out this assessment to learn about possible risk factors for breast cancer.

This risk assessment is not designed for people ages 40 to 74 who were assigned male at birth and have been on feminizing hormones for 5 or more years at any point in their life. However, these people qualify to screen in the Ontario Breast Screening Program and can contact their local Ontario Breast Screening Program location to learn more about how to get screened.
In this section we’ll ask about your family’s cancer history, which could affect your risk of breast cancer.
One case of breast or ovarian cancer and at least one other case of breast, ovarian, prostate or pancreatic cancer, on the same side of the family
Both breast and ovarian cancer in the same person
Breast cancer diagnosed in someone who was 35 or younger
Breast cancer in someone assigned male at birth
Ovarian cancer
More than one primary breast cancer in the same person
Here we’ll ask whether you or a family member has a genetic variant (change in a gene, also known as a mutation) that could affect your breast cancer risk.
Genetic testing (done through a blood test, usually at a genetics clinic) can tell you whether you have a genetic variant that raises your risk of developing breast cancer, as well as some other cancers.
Only select “No” if you’ve been tested and know for sure that you do not have these genetic variants.
This section asks about certain diagnoses, medical tests and drugs that may affect your risk of breast cancer.
Screening with a mammogram can help find cancer early, when treatment has a better chance of working. Screening every 2 years is recommended for eligible women, Two-Spirit people, trans people and nonbinary people ages 50 to 74.
People ages 40 to 49 should make an informed decision about whether breast cancer screening is right for them. To help make an informed decision about whether to get screened for breast cancer, people ages 40 to 49 are encouraged to talk with their doctor, nurse practitioner or a Health811 navigator about their personal risk for breast cancer, the potential benefits and potential harms of breast cancer screening, and what matters most to them in taking care of their health.
Here we’ll look at aspects of your life that may affect your breast cancer risk, such as how active you are.
This section asks about other risk factors, such as childbirth, breastfeeding or chestfeeding, menstruation, menopause and use of birth control pill.
Having more than 1 baby at a time, such as delivering twins or triplets, counts as giving birth once.
Include both vaginal and Cesarean/C-section births.
