Breast Cancer Causes And Health Effects

Genetics And Breast Cancer

It is no surprise a family history of a certain disease increases an individual's risk factor for that disease. Therefore, genetics is also another major risk factor, as if a female has at least one close relative who developed breast or ovarian cancer, they have a slightly higher chance of developing the disease. However, if two family members develop the disease, it does not mean they share the same genes that make them more susceptible to the development of cancer, as breast cancer is a common type, and majorities are not hereditary. Specifically, BRCA1 and BRCA2 genes may be inherited, and women carrying these genes are more than likely to develop breast cancer within their lifetime.
