How Do Genetic Factors Influence Cancer Susceptibility?
Genetic factors play a crucial role in cancer susceptibility. Certain genetic mutations can increase an individual's risk of developing cancer. For instance, mutations in the BRCA1 and BRCA2 genes are well-known for their association with increased breast and ovarian cancer risks. Moreover, variations in genes responsible for DNA repair mechanisms can compromise the body's ability to fix DNA damage caused by carcinogens, thus elevating cancer risk.
