(HealthDay News) — The risk of cancer remains high for women older than 50 years with BRCA1 or BRCA2 mutations, according to a study published in Cancer.

Researchers estimated the cumulative risks for all cancers in women from 50 to 75 years of age with a BRCA1 or BRCA2 pathogenic variant. The analysis included 2211 women seen at 85 centers in 16 countries who were followed until a diagnosis of cancer, death, age 75 years, or last follow-up.

A total of 379 cancers were diagnosed. The actuarial risk of any cancer was 49% for BRCA1 and 43% for BRCA2. The most frequent cancers were breast (n=186) and ovarian (n=45).
