This observational study aims to better understand breast, ovarian, fallopian tube, peritoneal, and endometrial cancers, especially in people at high genetic risk. Researchers will study how these cancers develop and how environmental factors might play a role. They will also evaluate how well treatments work for these diseases. You may be eligible if you are a woman aged 18 or older with a high risk of developing breast or ovarian cancer due to a known genetic change (mutation) in genes like BRCA1/2, PTEN, CDH1, or TP53, or if you have a strong family history of these cancers without a known genetic mutation. The study is also looking for women with sporadic breast cancer (no family history) and healthy volunteers without a personal or family history of cancer to serve as comparison groups. This study is currently unclear on its recruitment status.
