Serous cystadenocarcinoma is a type of ovarian cancer that originates from the epithelial cells of the ovaries. It is characterized by the presence of fluid-filled cysts and is often diagnosed at an advanced stage due to subtle symptoms. This cancer type is more common in women and can be aggressive, requiring prompt medical attention. The exact cause of serous cystadenocarcinoma is not fully understood, but genetic factors, such as mutations in the BRCA1 and BRCA2 genes, may increase the risk. Treatment typically involves a combination of surgery and chemotherapy to manage the disease and improve outcomes.
