"Current medical status: Abdominal discomfort (bloating, pain in left pelvis and under rib-cage, frequent urination, incomplete elimination, acid stomach accompanied by over-all itching sensation, nausea and dizziness, especially prior to ovulation). Symptoms are worsening each month and have occurred for over a year. A transvaginal ultrasound results: "left ovary is enlarged measuring 5 x 3.9 x 3.2 cm. A 4.1 x 3.2 x 2.7 echogenic lesion occupies most of left ovary. The lesion completely fills in with echoes and may represent a solid mass. Could represent a solid ovarian neoplasm or a large hemorrhagic cyst filled with clot." ca-125 results 400u/ml"
According to the ultrasound report and the Ca-125 result, it seems that you are experiencing some type of ovarian tumor. Ca-125 is a tumor marker for ovarian cancer but I can't make conclusions according only to the result (400 U/ml) without knowing the referent values of Ca-125. Every laboratory has its own referent values. You may need surgical intervention to remove the tumor together (with the affected ovary). Call your gynecologist immediately!!!
