BRCA Gene Changes: Cancer Risk and Genetic Testing
It is not yet clear whether these medications can be used to prevent breast cancer in women with greatly increased risk due to inherited harmful mutations in BRCA1, BRCA2, or other genes . However, tamoxifen may lower the risk of contralateral breast cancer among BRCA1 and BRCA2 variant carriers previously diagnosed with breast cancer ( 40 ).

Mutaciones en el gen BRCA: el riesgo de cáncer y las pruebas …
El BRCA1 (cáncer de seno 1) y el BRCA2 (cáncer de seno 2) son genes que producen proteínas que reparan daños en el ácido desoxirribonucleico (ADN). Cada persona hereda dos copias de cada uno de estos genes: una de la madre y una del padre. El BRCA1 y el BRCA2 a veces se conocen como genes supresores de tumores porque cuando tienen cambios específicos, …
Discovery – BRCA Connection to Breast and Ovarian Cancer
BRCA gene mutations are inherited. Early genetic research by NCI-supported investigators Mary-Claire King, Ph.D., Mark Skolnick, Ph.D., and their colleagues associated a DNA region with hereditary breast cancer. Researchers then identified the BRCA1 gene within this region, which established a clear association between inheriting the mutant forms of the gene (known as …

MRI, Surgery Reduce Cancer Deaths in Women with BRCA Changes
2024年4月15日 · For women in whom gene testing finds “harmful changes” in the BRCA1 or BRCA2 genes, leading medical groups recommend that they take specific actions to lower their chances of being diagnosed with or dying from breast and ovarian cancer.. Results from two recent large studies now add to findings from earlier studies suggesting that following those …
