Chronic inflammation caused by too little stomach acid leads to gastric cancer
...ric cancer, too little stomach acid can be just as dangerous as too much, according to scientists at the University of Michigan Medical School. Both extremes create inflammatory changes in the stomach lining and a condition called chronic atrophic gastritis, which over time often leads to cancer.
