Thank you very much for moving my message. Last three years were my S CEA levels: 8, 11, 15 and now two months after 15,5. It is only one marker. Gastroscopy and colonocsopy is ok. Now in November I go for CT belly and mamography. It was told me, it can be inflammation or I have my level high all my life and it is neither cancer nor inflammation but some defect of proteins. I was serching wheather has somebody else similar experiences. I am worried and I would like to know that everything is ok. I have troubles with pain in some muscles and with exclusion. Sorry for beeing so long
