Does HP positive in the stomach mean that I have to suffer from stomach cancer? A: You can’t think so, HP is infected by oral-digestive tract, mostly caused by poor hygiene and not washing hands before meals. When the body’s immune function decreases, the urease secreted by HP decomposes the urea in the stomach into ammonia, and ammonia works together with the toxins and cytokines produced by HP to produce inflammation in the gastric mucosa, which starts as superficial gastritis and gradually becomes atrophic gastritis if it continues to progress. Later, it develops into intestinal hyperplasia, heterogeneous hyperplasia and finally cancer, which usually takes more than 10 years. The cancer rate is not 100%, but about 5-10%, so HP infection is not terrible, and HP eradication can prevent the deterioration of the lesion.
