How do you know if you carry the breast cancer gene?
The BRCA gene test is a blood test that’s done to determine if you have changes (mutations) in your DNA that increase the risk of breast cancer. Mutations in either breast cancer gene — BRCA1 or BRCA2 — significantly increase the risk of: Breast cancer.
Can a father carry the breast cancer gene?
Most inherited cases of breast cancer are associated with two abnormal genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two). Men are just as likely as women to have an abnormal breast cancer gene.
Who carries the breast cancer gene?
You are substantially more likely to have a genetic mutation linked to breast cancer if: You have blood relatives (grandmothers, mother, sisters, aunts) on either your mother’s or father’s side of the family who had breast cancer diagnosed before age 50.
Can you be a carrier of breast cancer?
The study involved more than 5,000 women diagnosed with breast cancer before they turned 50; 211 were carriers of the BRCA1 or BRCA2 mutations. Over a nine-year period, 9% developed cancer in their other breast.
Does breast cancer skip a generation?
It’s important to note that most women who get breast cancer do not have a family history of the disease. But women who have close blood relatives with breast cancer have a higher risk: Having a first-degree relative (mother, sister, or daughter) with breast cancer almost doubles a woman’s risk.
Are you more likely to get breast cancer if your mother has it?
A woman’s risk for breast cancer is higher if she has a mother, sister, or daughter (first-degree relative) or multiple family members on either her mother’s or father’s side of the family who have had breast or ovarian cancer. Having a first-degree male relative with breast cancer also raises a woman’s risk.
Does having an aunt with breast cancer increase your risk?
If one or more of these relatives has had breast or ovarian cancer, your own risk is significantly increased. If a grandmother, aunt or cousin has been diagnosed with the disease, however, your personal risk is usually not significantly changed, unless many of these “secondary” relatives have had the disease.
What counts as family history of breast cancer?

Can you get breast cancer with no family history?
More than 75% of women with breast cancer have no family history of the disease and less than 10% have a known gene mutation that increases risk.
Is a history of breast cancer on the father’s side of the family important?
Your father’s side is equally important as your mother’s side in determining your personal risk for developing breast cancer. Inherited risk/genetic predisposition. There are several inherited genes linked with an increased risk of breast cancer, as well as other types of cancer.
How does a woman’s weight influence her breast cancer risk?
For women, being overweight or obese after menopause increases the risk of breast cancer. Having more fat tissue can increase your chance of getting breast cancer by raising estrogen levels. Also, women who are overweight tend to have higher levels of insulin, another hormone.
