Evaluation of metas: Cea or carcino embryonic antigen, is a cancer marker, a protein produced by embryonic cell regenerating cells, and cancer cells, it is little more specific in liver cancer. Cea is as monitoring device in cancers like breast after surgery with normal levels , shows elivation 4 years from treatment , means indicative of possible metastasis , and need further investigation for meta disease.

CEA: Carcinoembryonic antigen. Usually used as a marker for colon cancer but can be elevated in lung cancer and colon cancer. The normal level in non-smokers is less than 3. If the level is rising or very high, then one needs to start looking for a recurrence. Hope this helps.
