Hi everyone. I think I'm fully recovered from round one of IL-2, been home for 6 days and I'm feeling good. Feeling really good actually, I hope that's not a bad thing. I start my second round on Monday and am wondering, if I am fortunate enough to be one of the positive responders to the treatment, what would I expect to see? I was told that I'd probably be waiting for about 3 weeks to know if it's working. I can't find much information about IL-2 working on people, at least in detail. Do tumors just shrivel and die? I have a good sized cluster on my back and one on my chest about the size of a lima bean that I can actually see under my skin. The internal ones, I just have to hope for shrinkage. But would I actually be able to see these things physically get smaller? Also, I've heard from some people that tumors could actually swell or enlarge while being defeated. Has anyone heard or experienced this? I plan on asking my doctor these questions next time I see him, but until then, any information from anyone here would be really appreciated and put my sometimes worried mind at ease. Thankyou.
