Aimee, fear of cancer returning is something we all go through. Your ordeal has been really recent and because of that, it's all so fresh. After treatment, we all associated every pain, twitch, spot...everything different....our minds automatically goes to a sign of cancer. If you hadn't gone through cancer, would you think difficulty swallowing is a sign of cancer? Probably not. What I had to tell myself is, everyone has a pain sometimes. Everyone feels something different in their bodies at some point or another. Definitely let your oncologist know of all of your concerns but don't live in fear. Easier said than done but as time goes on,it will get easier.
Praying for your peace of mind! Blessings!
