What's the time frame here?
I had non-Hodgkin's lymphoma about 30 years before WLS and it affected most of my body. I went through nine months of experimental chemotherapy (as there were no standard in those days). My oncologist wanted me to joint a support group of about eight other young women in SoCal, all of whom had non-Hodgkin's lympoma and had taken tetracyclin and birth control pills prior to diagnosis. The thought was that was a connection between the prescriptions and the diagnosis of cancer. I declined, for various and sundry reasons and it turned out to be a good decision in so many ways. We were all on different protocols for chemotherary and/or radiation and the reason I am glad I declined to participate in the group therapy is that I am the only one who survived.
I know it's more than you asked for. I guess it's my way of fist-bumping with you, WE SURVIVED.
I don't know about RNY but I'm fairly certain you could get WLS of some sort. However, I would recommend that you attend a free information session and ask a lot of pointed questions. I'm annoyed as hell on your behalf about the $250.
