Can 6-MP cause cancer ?

My GI doc is putting me on 100 mg of Mercaptopurine 6-MP and told me I could get skin cancer or blood cancer because my immune system will be suppressed. Has anyone else ever been told this ? What is the likelihood of getting skin or blood cancer ? I am considering going off 6-MP on my own and trying an aloe vera supplement that has kept a lot of people in remission.

Its a rare scenario, was what our GI told us. My husband was on 50 mg for 6 months and the only side effects he had was hairfall and gas. Hair fall stabilized after 2 months and gas stopped after he came off the meds. GI told us to be on the lookout for side effects the first 2 weeks. He said if the medicine doesnt agree with your body, you will know immediately. If you cross the 2 week mark and feel ok, 6-MP is ok for you.

He also said the major side effects (like lymphoma) are possible if you are on it for more than 2 years and he promised he will only put him on for 6 months. There are a lot of people on this forum who are on it for a long time. Hope they pop in and help!

Good luck

I was on Imuran the sister drug for a bit over a year. It does slightly increase your risk of cancer. Primarily melanoma because it causes sun sensitivity (so wear sunscreen). Lymphoma like Madhu said is primarily seen in long term users (2+ years). And is still very rare. Uncontrolled Crohns is more dangerous in that continual inflammation can lead to increased cancer risk. It worked awesome for me and I only had a bit of fatigue that reduced after 3 weeks. I would strongly reccomend staying on it. It's an effective drug that has proven studies behind it.
