[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. CA 125 is tumor marker which indicates tumor activity. So it is used in patients who had surgical removal or taken chemotherapy. It is very good marker to suspect relapse or worsening of cancer. You initially had higher CA 125 levels. Then after surgery your level is decreased. This is due to decrease in tumor burden because of surgical removal. But again value raised after chemotherapy. So this indicates, worsening of underlying malignancy. So in my opinion, you should consult your cancer doctor and get done repeat CT scan to rule out worsening of underlying tumor. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
