Breast cancer is not necessarily caused by hereditary factors. The majority of breast cancer cases are associated with mutations in cells that were developed during a person's lifetime.
However, there is a small percentage of breast cancer patients who do acquire the disease because of genetic predispositions. Mutations in BRCA1 and BRCA2 genes can be inherited, which will increase a person's chances of developing breast cancer. But not everybody who inherits these mutations will develop the disease.
Breast cancer is more common in women than in men, but men can also inherit BRCA mutations. This means men can also be at risk of developing breast cancer and also for passing on the mutated genes to their children.
If you have these genetic mutations or a strong family history of breast cancer, it is sometimes recommended to receive a breast MRI and a mammogram every year at a younger age.
Screening for breast cancer early and often can help catch the disease at an early stage. And catching the disease at an early stage will increase your chances of survival.
Inherited breast cancer is caused by two abnormal genes, BRCA1 and BRCA2, or breast cancer gene one and breast cancer gene two. Everyone has these genes, but when there are abnormalities present in these genes that is when there is a risk for breast cancer.
