I have had crohns for 35 yrs. been on 6mp for @ least 15 yrs or more. have had good results till recently. the 6mp has now given me squamous cell carcinoma skin cancer & i have warts all over my feet, legs hands-everywhere. i am having surgery soon for the skin cancer-when i am done w-these surgeries i will have had 13 in a year-not counting the hundreds i have had removed in last 10 yrs,plus the thousands i have had froze off. my gastro wants me to stop the 6mp-just stop it. my concern is - can u just stop it w-out weaning off of it especially since i have been on it so long. he wants me to switch to methetrexate (sp?) which makes no sense goin from 1 chemo drug to the next. i dont want to go on any more drugs. the last 2 yrs i have been takin sulfameth & tmp tabs once daily which have really helped. Anyway has anyone been on 6mp that long & just stopped?
