Ovarian Clear Cell Carcinoma (OCCC) is a rare subtype of ovarian cancer that primarily affects the ovaries. It is characterized by clear cells that appear under a microscope, which distinguishes it from other types of ovarian tumors. OCCC often presents at an advanced stage and may be associated with endometriosis, a condition where tissue similar to the lining of the uterus grows outside it. The exact cause of OCCC is not well understood, but it is believed to have different biological behaviors compared to other ovarian cancers. Treatment typically involves a combination of surgery and chemotherapy, although OCCC may be less responsive to standard chemotherapy regimens. Early diagnosis and tailored treatment are crucial for improving outcomes.
