Genetic Risk for Breast Cancer

Despite a number of major breakthroughs in the field of genetics and cancer research, breast cancer still remains a killer disease. While lifestyle and environment can significantly contribute to the development of breast cancer, heredity does play an important role. And so far as hereditary breast cancer is concerned, mainly two genes account for the development of the disease. Genetic risk factors for breast cancer are closely associated with two genes: BRCA1, which stands for BReast CAncer gene one, and BRCA2, or BReast CAncer gene two.
Let’s explain how BRCA gene 1and 2 contribute to the genetic risk for breast cancer.
In their normal state, BRCA1 and 2 perform an important task- they keep the growth of breast cells at a normal level. In this way they also prevent the growth of cancer cells. Sometimes BRCA genes 1 and 2 have abnormalities or mutations. People are either born with abnormal BRCA gene 1 and 2 or they acquire abnormalities during lifetime. In any case, mutated BRCA1 and BRCA2 genes enhance the genetic risk for breast cancer. In fact BRCA1 and BRCA2 mutations are the cause for some 10% of all breast cancer cases.

There are several genetic mutations that are recognized, and
people with
this mutation have an 80% chance of getting breast cancer.
You can be
tested for these mutations.
Apart from those particular mutations,
cancer tends to run in families,
so there is at least some genetic
component besides known mutations.!!

Yes, there are blood tests that can be ran to help detect if someone has a genetic tendency toward getting breast cancer. A woman can also look into family history to find other women who have had the diagnosis of breast cancer. Specifically, the woman's maternal family history can be a tell-tell sign/risk factor for breast cancer.
