Inflamed ovaries may be caused by tumors, both benign and malignant. When a doctor diagnoses a patient with a tumor, blood tests or transvaginal ultrasounds can enable further investigation. Ovarian cancer causes malignant tumors, which affect around 1.2 million women worldwide. Ovarian cancer is often misdiagnosed as irritable bowel syndrome, as the symptoms are similar. Treatment involves a mix of surgery, chemotherapy, and radiation therapy.
