A man who inherits a BRCA1 or BRCA2 mutation: may have a small increase in his risk of developing breast cancer (this is mainly if he has the BRCA2 mutation) may have a higher risk of prostate or pancreatic cancer (mainly BRCA2) has a 1 in 2 (50%) chance of passing the mutation on to each of his children.

BRCA1 and BRCA2 mutations are passed through families. A person with a BRCA1 or BRCA2 mutation is more likely to get breast, ovarian, and other cancers. Genetic counseling and testing for BRCA1 and BRCA2 mutations can provide information about their risk. If they choose to be tested, they should be tested for the same mutation that you have.

Men with a BRCA1 mutation also have a 1% risk of breast cancer, and a 6% risk with a BRCA2 mutation. Women and men with a BRCA mutation also tend to develop breast cancer at a younger age. Objective. Female carriers of BRCA1/BRCA2 mutations (BRCAm) are at increased risk of developing breast and ovarian cancer. The main prevention options currently available consist in either clinical‐radiological surveillance or risk‐reducing surgery. We identified eight (0.7%) BRCA1 and 16 (1.3%) BRCA2 mutation carriers in 1220 breast cancer cases (actual sample size 1435 adjusted for 15% polymerase chain reaction failure rate).

The frequencies of mutations in the BRCA1 and BRCA2 genes differ across populations. Between 1997 and 2000, 160 families with breast and/or ovarian cancer  Sixteen (27%) of the families were found to carry nine different BRCA mutations, including 14 families with BRCA1 mutation and two families with BRCA2  BRCA1 and BRCA2 Mutation in Romanian Population: a Study of Genotype - Phenotype Correlation at Diagnosis With Prospective Disease Outcome and  av H Eerola — bröstcancer.

But some mutations in the BRCA1 and BRCA2 genes prevent them from working properly, so that if you inherit one of these mutations, you are more likely to get breast, ovarian, and other cancers. However, not everyone who inherits a BRCA1 or BRCA2 mutation will get breast or ovarian cancer. Everyone has two copies of the BRCA1 and BRCA2 genes, one copy inherited from their mother and BRCA1 (BReast CAncer gene 1) and BRCA2 (BReast CAncer gene 2) are genes that produce proteins that help repair damaged DNA. Everyone has two copies of each of these genes—one copy inherited from each parent.

For those with BRCA1 mutations, 39% are expected to develop ovarian cancer, while 11% to 17% of those with a BRCA2 mutation will develop the disease. There are other cancers that can be associated with BRCA mutations as well, such as prostate cancer, pancreatic cancer, and even lung cancer.

Patients and methods: Four hundred eighty-three women with disease-associated germline BRCA1/2 mutations were studied for the occurrence of breast cancer. Cases were mutation carriers who underwent bilateral prophylactic mastectomy and who were followed prospectively from the time of their center ascertainment and their surgery, with analyses performed for both follow-up periods. BRCA1 and BRCA2 mutation analysis in breast-ovarian cancer families from northeastern Poland. Perkowska M(1), BroZek I, Wysocka B, Haraldsson K, Sandberg T, Johansson U, Sellberg G, Borg A, Limon J. Author information: (1)Department of Biology and Genetics, Medical University of Gdańsk, Poland. The mean annual rate of invasive breast cancer was 1.8% for BRCA1 mutation carriers and 1.7% for BRCA2 mutation carriers. The cumulative risk of invasive breast cancer from age 60 to 80 was 20.1% for women with a BRCA1 mutation and was 17.3% for women with a BRCA2 mutation.
