Has anyone else in this forum taken Zantac prior to being diagnosed with bladder cancer? I used Zantac on-and-off for several years to relieve heartburn and acid indigestion. It worked really well! Since I have never been a smoker, and since nobody else in my family ever had this cancer, Zantac seems to be the likely suspect. I'd be interested to know if there are others in the forum who took this drug. Thanks.
