The diagnosis of PPC typically involves a combination of imaging studies, blood tests, and biopsies. Imaging techniques such as CT scans, MRI, and PET scans are commonly used to identify abnormal growths. Blood tests may include checking for elevated levels of CA-125, a tumor marker often elevated in ovarian and peritoneal cancers. Definitive diagnosis is usually confirmed through a biopsy, where a tissue sample is examined microscopically.
