Had my first colonoscopy in 2016. One polyp was removed. It came up as cancer stage 1. Colon resection was done 2 weeks later. CEA levels are checked every six months, which have all been WNL. CEA level in 2/2018 was 0.5. This last CEA done 9/2018 came up to 3.0. Really worried and scared since this is the first abnormal level. I have seen my oncologist and CT scan and GI visit recommended. I have had mammo, transvaginal ultrasounds, chest xrays, CT of chest done all within the past year along with echcardiograms, stress tests and heart cath..all normal. Any opinions greatly appreciated.
