Hello @shilo14, Thanks for the welcome and the FB referral. This is all very new to me, but it was my understanding that the outlook for survival with thymomas was extremely positive - more a matter of what survival looks like. As an example, from the limited data I'm finding, it looks like phrenic nerve damage occurs in about a third of patients. Apparently, there is very little room in the mediastinum area for surgeons to work and collateral damage is an unfortunate reality of that. If I had it all to do over, I would have monitored my tumor a lot better and caught it before it became so large. But when you don't have any symptoms from it, it's easy to just put it out of your mind in the hustle and bustle of the day-to-day. Anyway, thanks again and be well.
