last stages of superficial bladder cancer

I have Rhumatoid Arthritis and as such take drugs to combat this
The ones relevant to here are
Methotrexate 20mg ONCE per week
Prednisolone 5mg once per day
Lipitor (cholestorol reducer) 10mg once per day.
History / recected tumor 2cm X 1CM and two other minor patches 3 months treated mytomycin 6 weeks 6 months after scatter type cancer noted treatment Rigid Cystoscophy biopsies positive advised to try BCG.
BCG being immunotherapy the drugs I take for RA restrict my immune system as such I worked closely with the urology nurse to enable me to get fit enough to stop immuno suppresants for the the duration.
Treatment Could not hold BCG first time as could not tolerate the anaesthetic, was far better with KY jelly on the cathiter.
Got hay feaver first time in life, no treatment
5 weeks in started developing a rash on the legs (Name escapes me)itched like hell, suffered. 7 weeks had to resort to prednisolone to cure rash, wanted 8 weeks but doc said enough was enough. Rash was on every part of skin that had any pressure on it, cleared in 2 days. Result is a year free of cancer. Am I cured no, like the smoking I used to do, not at the moment and I have grea hopes for total remission. My story I tell because I believe there is an advantage to restricting the immune system then at an appropriate time letting it go. My immune system wanted to pick fights with anything as such I believe My RA may have benefited me in a round about way, I ask you to consider my story as to your treatment for superficial bladder cancer
