A CEA test can be used for the following purposes:
- People with certain types of cancer should have their treatment monitored. Colon cancer, as well as cancers of the rectum, prostate, ovary, lung, thyroid, and liver, are examples.
- Determine the stage of your cancer. This includes determining the size of the tumour and the extent to which the cancer has spread.
- Check to see if the cancer has returned after treatment.
