Hi there, If I could give you some advice. I too have ulcerative colitis and had to be put on imuran after being on predisone for years. Imuran nearly killed me, literally. My blood was so depleted that my doctor told me I should have had a stroke or a heart attack. He said that by the standards in the medical books I should have been dead. I had go to the hospital and for the next six weeks I had to get blood transfusions. I was weak and very sick. Years later, about
6 years, I found a lump in my breast. They called it a pyollodes
tumor. I needed two surgeries to take the lump out, but I didn't need any further treatment, thank God! If you look at the side effects of Imuran, it does mention breat cancer. I have to tell anyone who asks me if I am allergic to any medication about Imuran. It nearly killed me!
I am not telling you this to scare you, I am telling you this so that you know what can happen and did happen to me. I wish you all the best and if possible, please let me know what you decided.
Best of luck!!
