1 in 5 relatives of breast and ovarian cancer patients in Estonia carry dangerous cancer genes

A new study from Estonia reveals that approximately 20% of relatives of breast and ovarian cancer patients carry pathogenic variants of the BRCA1 or BRCA2 genes, which significantly increase cancer risk. These dangerous gene variants can be inherited within families, making genetic testing crucial for at-risk relatives. The findings echo the impact of Angelina Jolie's 2013 disclosure about carrying a BRCA1 variant, which sparked global awareness about preventive testing. Knowing your genetic status enables informed decisions about screening, prevention, and medical management that could be lifesaving.
