The prevalence of harmful BRCA gene changes in the general population is about 0.2%–0.3% (or about 1 in 400). However, in certain populations that are geographically or culturally distinct, the prevalence of specific BRCA mutations—called founder mutations—is higher.

Key points: BRCA1/2 -associated ovarian cancers are more likely to have high-grade serous adenocarcinoma histologies. Occult lesions found in the fallopian tubes of BRCA carriers suggest that many BRCA -associated ovarian cancers may originate in the fallopian tubes.

Apr 15, 2024 · For women with inherited harmful changes in BRCA genes, MRI surveillance and salpingo-oophorectomy can modestly reduce their risk of dying from breast and ovarian cancer, results from two studies show.

A fact sheet about research on the association of oral contraceptive use (birth control pills) with risk of various cancers.

Los cambios dañinos en BRCA que se detectan en el tumor pueden ser hereditarios o haber surgido en otro momento de la vida de la persona. Por este motivo, si se identifica un cambio en el tumor, es importante hacerse una prueba para averiguar si es hereditario.

The Breast Cancer Risk Assessment Tool (BCRAT) is an interactive calculator that estimates a woman's risk of developing breast cancer. Also known as The Gail Model. Designed by scientists at the National Cancer Institute and the NSABP.

Long before scientists completed mapping the human genome in 2003, geneticist Mary-Claire King discovered BRCA1, the first gene for a hereditary form of breast cancer. That feat in 1990 helped explain why some women who carried mutations in this gene saw their lifetime risk for developing breast cancer rise from 8% to over 80%. Although Dr. King and her colleagues at the University of ...

Factors included: patient's personal medical and reproductive history and the history of breast cancer among her first-degree relatives (mother, sisters, daughters). For comparison, the tool also presents 5-year and lifetime risk estimates for a woman of the same age and race/ethnicity who is at average risk for developing breast cancer.

As of January 2024, the only FDA-approved DTC genetic test for inherited cancer risk tests for three different BRCA gene variants that are common in people of Ashkenazi Jewish descent.
