Hi Friend1, Yes, you are right it can lead to cancer. It appears that your digestion is very slow. Simple diet changes are very helpful. Drinking more water should be on the top of the list. Avoiding coffee, soda, and alcohol since these will dehydrate the body. Limit meat intake to mid day to early afternoon if possible. Avoid dairy products also, they are easy to swallow, but hard to digest. Fresh fruits and vegetables since they have enzymes to help digestion. These are simple changes that can really make a difference. My neighbor who is in her 80's suffers from this and her doctor told her to put her raise the head of her bed a few inches so the acid will not come up at night when she goes to bed? If I can be of further help please feel free to email me. My best to you. Sincerely, Marcie
