I have read some articles about people who have had a tumor on their thymus and it didn’t show up on the MRI or CT. That is a huge concern with me as well. I really do not want to give up my thymus and I have been doing so well with treatment with it. At the end of the study I will have the option to have my thymus removed. I think I will keep it though. If I end up getting worse I think I will consider that option.
