Serous carcinoma is a type of cancer that primarily affects the ovaries but can also occur in other organs, such as the uterus and fallopian tubes. It is characterized by the presence of serous fluid, which is a thin, watery fluid produced by the body. This cancer is often aggressive and is typically diagnosed at an advanced stage, making treatment more challenging. The most common form of serous carcinoma is high-grade serous carcinoma, which is known for its rapid growth and tendency to spread quickly. Risk factors include family history, genetic mutations like BRCA1 and BRCA2, and age. Early detection is crucial for improving outcomes, and treatment usually involves a combination of surgery and chemotherapy.
