Awhile back, I had a patient in the hospital with aggressive bladder cancer that was considering chemo after her surgery to remove the tumor. I told them everything I knew about the cancer and what the odds of survival were with chemo and whatever else I could. The family wished to discuss it further with one another and I told them I'd check back tomorrow. As I was walking out the door, I heard one of the sons say, "I'm going to run home and get you some apple cider vinegar, Mom. Couple of shots of that will fix anything wrong with your bladder."
