Papillary Serous Carcinoma is a type of cancer that primarily affects the ovaries, although it can also occur in other areas such as the uterus and fallopian tubes. It is characterized by the presence of finger-like projections (papillae) and is often aggressive, making early detection crucial for effective treatment. This cancer is classified as a subtype of serous carcinoma, which is the most common form of ovarian cancer. Risk factors include family history, genetic mutations like BRCA1 and BRCA2, and age. Treatment typically involves surgery and chemotherapy, depending on the stage of the disease.
