Breast can.cer and ovarian can.cer are two of the most common can.cers affecting women. While they impact different organs, growing research shows that they can be biologically connected—especially through genetics. Understanding this link can help women take informed steps toward prevention, early detection, and treatment.
Shared Genetic Risk Factors
One of the most important connections between ovarian and breast can.cer is the presence of mutations in the BRCA1 and BRCA2 genes. These genes normally help repair damaged DNA and prevent tumor growth. However, mutations in BRCA1 or BRCA2 significantly increase a woman’s risk of developing both breast and ovarian cancers.
