Hereditary Cancer Risk Tool

This simple tool will assess your risk of having inherited a genetic mutation that could increase your risk of developing certain cancers. It's suitable for both men and women.

All you need is a few minutes and some information about your family history of cancer, including the age any relatives were diagnosed.

If you are unsure about your family history we recommend you speak to your relatives to find out if anyone in your extended family has been diagnosed with cancer. You can find advice on how to approach these conversations and a family tree template on our website.

This tool doesn’t assess your risks of having inherited all possible genetic mutations; it assesses criteria relating to BRCA mutations (BRCA1 and BRCA2) and Lynch Syndrome (hereditary non-polyposis colorectal cancer- includes MLH1, MSH2, MSH6, PMS2, and EPCAM). If you are concerned about any other hereditary cancer in your family, please speak to your GP.

Explore your risk

Please note: This tool is based on the information you are able to provide and how it relates to the current referral guidelines in England, Northern Ireland, Scotland and Wales. Guidelines vary across the world so please refer to your local guidelines if you reside outside the United Kingdom. Care has been taken to ensure that the information we provide in this tool is as accurate as possible and has been reviewed by a geneticist.
