The Genetic Component
Genetic factors play a role in all cancers, but only about 5-10% of cases are truly 'hereditary'—meaning they are caused by an inherited gene mutation passed from parent to child.
Somatic vs. Germline Mutations
Most cancers are caused by somatic mutations that accumulate over time due to aging and environment. Germline mutations, however, are present from birth and increase the likelihood of developing specific cancers at an earlier age.
Genetic Counseling
If you have a strong family history of cancer, genetic testing can identify specific risks (like the BRCA gene) and allow for proactive monitoring and early intervention.
