How to Use the Breast Cancer Risk Checker
Breast cancer is one of the cancers where early detection has the biggest impact on treatment success, so understanding your known risk factors helps you plan when to start screening. Enter your age along with family history, genetic mutation status, reproductive history, and dense breast tissue status, and this checker converts them into a score, then shows a risk level and recommended screening plan.
A mother, sister, or daughter with breast cancer — especially a diagnosis before age 40 — or a confirmed or strongly suspected BRCA1/2 mutation are among the strongest risk factors, while dense breast tissue, an abnormal prior biopsy, and having no children or a first birth after 30 also raise the score. In the U.S., the USPSTF recommends a mammogram every 2 years starting at age 40 regardless of risk factors, while some organizations like the American Cancer Society support starting annual mammograms as early as 40-45; higher-risk individuals may be advised to start earlier, screen more often, or add breast MRI.
This tool simply totals known risk factors for reference — it is not a diagnostic test and cannot confirm or rule out breast cancer. Even a low score doesn't mean you should skip screening once you reach the recommended age, and regular breast self-awareness (getting familiar with how your breasts normally look and feel) is worth building into a habit regardless of your score. Use this result only as a starting point for a conversation — a breast specialist or your primary care doctor can give you an accurate diagnosis and a personalized screening plan.
Frequently Asked Questions
The USPSTF recommends a mammogram every 2 years starting at age 40, while the American Cancer Society allows starting annual screening as early as 40-45 depending on personal preference. If you have several risk factors, talk to your doctor about starting earlier or more often.
No. Regardless of your score, getting familiar with how your breasts normally look and feel and checking periodically helps you notice changes early. This result is not a reason to skip screening or self-checks.
