I undertand your feelings Emily, having had 5 recurrences myself, and can't help thinking if it will return, but I believe it shows your concern about your health, and other matters, and is better than no thoughts at all. It's only natural, but when it interferes with your daily living it's a concern, but there can be postive prepardness too. In fact, I finished treatment on the 19th, and had a break in between, but I need to get All my medical records for future reference, so I don't get caught short again. When you think you have enough, someone always asks for something you don't have, and my local oncologist just did the other day for my blood work from treatments lol. I also need to see doctors I have not seen in a few months since I may call on them again, one day. Being diligent in seeing your doctor about any medical concerns is being proactive, and good too, and doubt any good doctor would disagree, otherwise, why would we need them, and may rely on Dr. Google instead. Updating or changing your medical plan, doctors, insurance, wills, occupations, diet, and even spiritual thoughts often results in these thoughts. I like to think we may not always be ok, and that's ok too, I'm prepared.

Take care.
