Breast Cancer Risk Assessment - A Collection of Web-based Tools


Updated February 09, 2009

How To Use These Risk Assessment Tools:

If you’re curious about your risk of being diagnosed with breast cancer, here are some online tools to help you. Most of these are simple questionnaires. None of these require you to enter confidential information, or to sign up for an account. I have tried all of these tools and reviewed them for you. The results from any of these tools should never be considered as a medical diagnosis – please talk to your doctor if you have any concerns about your breast health.

Who Benefits From These Tools?:

These four online risk assessment tools are for women who have never been diagnosed with breast cancer. If you're worried about breast symptoms, read up on types of breast lumps and benign breast conditions, and be sure to visit your doctor for a clinical breast exam.
