What Causes Cancer Variability in the Human Population?
Cancer variability in the human population arises from a combination of genetic, environmental, and lifestyle factors. Genetic predisposition plays a crucial role as certain gene mutations can increase susceptibility to different types of cancer. For instance, mutations in the BRCA1 and BRCA2 genes are strongly linked to a higher risk of breast and ovarian cancers.
Environmental factors such as exposure to carcinogens, radiation, and certain chemicals can significantly influence cancer variability. Lifestyle choices including diet, physical activity, and smoking also contribute to the differences in cancer incidence and progression among individuals.
