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?
It mainly is found in breast tissue, so it is breast cancer.
Well, definitely scary for a woman to find out. Are there other genes like that?
Breast cancer screening
Breast cancer screening is the medical screening of asymptomatic, apparently healthy women for breast cancer in an attempt to achieve an earlier diagnosis. The assumption is that early detection will improve outcomes. A number of screening tests have been employed, including clinical and self breast exams, mammography, genetic screening, ultrasound, and magnetic resonance imaging.
A clinical or self breast exam involves feeling the breast for lumps or other abnormalities. Medical evidence, however, does not support its use in women with a typical risk
.
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
