Anyone have information for bladder cancer outside of: broccoli sprouts, melatonin and curcumin? A friend has recurrent bladder cancer x2. He already takes Vitamin C and D although I am not sure re. the dosage. Unfortunately he and his wife, both in their 80’s, are vaxed and boosted. They believe their doctors implicitly and fell into the a Covid scare. Both have cardiac issues too.
