It's understandable to feel concerned when there's a change in your CEA levels, especially after a period of stability. CEA, or carcinoembryonic antigen, is a marker that can be used to monitor the treatment response in some cancers, including lung cancer. An increase could suggest a few different things, such as a change in the cancer's behavior or a response to treatment.

Since you've been on Tagrisso (osimertinib) for 18 months, it's important to discuss this change with your oncologist. They might recommend further testing or imaging to understand the cause of the increase in CEA levels. It's also possible that adjustments to your treatment plan might be considered based on these results.

Remember, you're not alone in this, and it's good that you're monitoring your health closely. Keep communicating openly with your healthcare team about your concerns and observations.
