Diagnosis typically involves a combination of screening tests, imaging studies, and biopsies. For cervical cancer, a Pap smear and HPV testing are crucial. Ovarian cancer may be evaluated through pelvic exams, transvaginal ultrasound, and blood tests like CA-125. Endometrial cancer is often diagnosed via endometrial biopsy and pelvic ultrasound. Vaginal and vulvar cancers require a biopsy of suspicious areas.
