One of my biggest fears is getting cancer one day. Especially when 5-10 percent can come from inherited genes.
Yes, the thought of cancer scares me too, I knew it had a genetic connection, but wasn't sure how much.
The BRCA2 gene is one of them,  it's responsible for repairing DNA but is susceptible to turning cancerous.
Does it cause a variety of cancers, or specific ones?
(specifically, a caretaker gene), found in all humans; its protein, also called by the synonym breast cancer type 2 susceptibility protein, is responsible for repairing DNA.
BRCA2 and BRCA1 are normally expressed in the cells of breast and other tissue, where they help repair damaged DNA or destroy cells if DNA cannot be repaired. They are involved in the repair of chromosomal damage with an important role in the error-free repair of DNA double strand breaks. If BRCA1 or BRCA2 itself is damaged by a

A family history of ovarian cancer is a risk factor for ovarian cancer. People with hereditary nonpolyposis colon cancer (Lynch syndrome), and those with BRCA-1 and BRCA-2 genetic abnormalities are at increased risk.
The major genetic risk factor for ovarian cancer is a mutation in "BRCA1" or "BRCA2" DNA mismatch repair genes, which is present in 10% of ovarian cancer cases. Only one allele need be mutated to place a person at high risk. The gene can be inherited through either the maternal or
