<s>[INST] 2 years ago I had a very large ovarian mass. I had a salphingo oopherectomy and a frozen section done diagnosed with stage 1c ovarian cancer. My CA 125 levels dropped to 0 and remained at 0 for 2 years over the last 6 months the levels have crept up in march they were at 79 yesterday they were at 200. Since the operation I have had a mirena coil fitted and I have not had a period. I am obese and cant feel any lumps like last time and a TVS didnt pick anything up. Got a CT Scan in 2 weeks should I be worried? [/INST] Hi, dairy have gone through your question. I can understand your concern. You have history of ovarian cancer.  However, it was stage 1c. So it has very good prognosis. You have already gone through salting oophorectomy.  So no need to worry. Your CA 125 level is increased.  You should go for ultrasound abdomen or ct scan of abdomen.  If you find any mass then you should take treatment accordingly. If you don't find any mass then repeat your CA 125 level every month.  Till it goes below 5. Then you should repeat every 3 month. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
