Hereditary Cancer and Genetic Testing

Cancer risk associated with inherited  mutations

If you have tested positive for an inherited  mutation, we recommend that you speak with a genetics expert who can look at your personal and family history of cancer and can help you choose the best plan for managing your cancer risk.


Breast cancer risk

  • Women have a lifetime risk of 20-40 percent.  
  • Men may also be at increased risk for breast cancer, but the exact risk is unknown. 


Colorectal cancer risk

People who inherit a mutation may be at increased risk of colorectal cancer. More research is needed to understand the lifetime colorectal cancer risk for people with mutations.

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

NCT02665195: Registry Of MultiPlex Testing (PROMPT). PROMPT is an online research registry. The goal of PROMPT is to help researchers to better understand the risks that are linked to mutations in less well-studied genes. People with inherited mutations can enroll in PROMPT to help researchers learn more about cancer risks.
