Cancer risks associated with an inherited  mutation

If you have tested positive for a  mutation, we recommend consulting with a genetics expert who can assess your personal and family history of cancer, and can help you decide on a plan to manage your cancer risk.

People with an inherited  have a greatly increased lifetime risk of developing several types of cancer, with about an 85 percent lifetime risk for developing any cancer. The risks for cancer tend to happen at a younger age compared to people who do not have a mutation. Note that when we use "men" and "women" we are referring to the sex you were assigned at birth.

 
Cancer type Lifetime risk with a  mutation Lifetime risk in general population
Breast (female) 40 - 60% 12.5%
Endometrial 25 - 30% 3.1%
Thyroid cancer (and benign thyroid growths) up to 38% 1.0%
Kidney up to 35% 1-2%
Colorectal 10 - 20% 2.4%
Melanoma  6% 2.5%

It is important to note that cancer risks are estimates over the course of a person's lifetime. Your lifetime risk and risk over the next five years will vary depending on:

  • current age
  • sex assigned at birth
  • specific mutation
  • personal and family health history
  • diet, exercise, lifestyle and other factors
