Hereditary cancer testing, also known as hereditary cancer risk assessment or genetic testing for cancer predisposition, is a specialized genetic test that determines if you have inherited a mutation in specific genes (such as BRCA1, BRCA2, or others associated with Lynch syndrome) that significantly increases your lifetime risk of developing certain cancers.

  • How it Works: The test usually requires a small sample of your blood or saliva, which is analyzed in a laboratory for germline mutations.

  • Benefits: Understanding your inherited risk allows for more personalized and proactive healthcare, including earlier and more frequent cancer screenings, risk-reducing strategies (like medication or surgery), and informed family planning. It also helps your relatives understand their potential risks.
