Cancer Risks Associated with Inherited Mutations

People with an mutation have . mutations increase the risk for colorectal, endometrial and other types of cancer listed in the table below. Mutations in affect another  gene called . For this reason, the cancer risks for people with and mutations are similar. 

If you or a relative have tested positive for an  mutation, we recommend speaking with a genetics expert. They can look at your personal and family medical history to help you understand and decide on a plan for managing your risk.

Other cancers

People with an inherited  mutation may have an increased risk for other cancers. The exact risks for the following cancers are unknown:

  • pancreatic cancer
  • sebaceous skin growths
  • female breast cancer

Research on how inherited mutations in the  gene affect cancer risk is ongoing.

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
