Congratulations on being a 3x cancer fighter! I never say survivor, and I'm a 8x cancer fighter myself, and proud to say that. I feel your pain, your uncertainty, fears, even if it was a small bump. It doesn't get any easier each time, and each is like the first, having to go through the same testing, worry, wait, and is probably even worst than the first time knowing what you went through, can go through, and what limited treatments may be left. I'm glad this was not found cancerous, but probably will need to be monitored, and you are at the best place to do so, MD Anderson.
Before you do anything rash, maybe speak to your doctors on their thoughts. Personally, I've been through worst, speaking of myself, and wouldn't give up anything I have or regained now, including work if I did, but I haven't work in 4 years lol, not by choice, being situations are beyond our control sometimes, and wish everyday I could. Your thoughts, and situation may be different, and to each their own, but the main thing is to keep fighting! I say this now, maybe next week my thoughts will change

All the best.
