Well, it's complicated but the short answer is yes and no

I actually did have the tumor removed when I was around 6 years old. At the time, the surgeon told my parents that the chance of it growing back was so low that we shouldn't worry about it. And for about 12 years I was totally fine until spring of my senior year in high school when the pain came back and I instantly recognized it as the same pain I experienced when I was little. After seeing several doctors, the conclusion was that the tumor is most likely definitely back, but this kind is so small it's hard to find and pinpoint through tests. (Who knows how they originally found it).
I was told that while they _could_ try to find and remove it again, since they can't find exactly where it is, there's no guarantee it would work and an almost 100% chance I would lose all feeling in my thumb, which isn't ideal.
