Diagnosis typically involves a combination of imaging studies, laboratory tests, and sometimes surgical procedures. - Imaging Studies: Techniques such as CT scans, MRI, and PET scans can help visualize the extent of the disease. - Laboratory Tests: Blood tests, including tumor markers like CA-125, can provide additional information. - Surgical Procedures: A biopsy or exploratory laparoscopy may be performed to confirm the diagnosis and assess the extent of peritoneal involvement.
