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 serous fluid, which is a thin, watery substance. This cancer is often aggressive and can spread quickly, making early detection important for effective treatment. The most common form of serous carcinoma is high-grade serous carcinoma, which is known for its rapid growth and tendency to metastasize. Risk factors include genetic mutations, such as those in the BRCA1 and BRCA2 genes, as well as family history. Treatment typically involves a combination of surgery and chemotherapy.
