What role do genetic mutations play in cancer risk?
Genetic mutations can either be inherited or acquired. Inherited mutations are passed down from parents to offspring and can significantly increase the risk of certain cancers. For example, mutations in the BRCA1 and BRCA2 genes increase the risk of breast and ovarian cancers. Acquired mutations occur during a person's lifetime due to environmental factors or errors in DNA replication. Identifying genetic mutations through testing can guide preventive measures and targeted therapies.
