How long does gastric bile reflux cause cancer

It was difficult to determine exactly how long it would take for cancer to occur, because everyone's physical fitness was different. If it was simple bile reflux, the chance of cancer occurring was relatively small, and if it would cause cancer, it would take at least several decades. However, if bile reflux also caused gastric mucosal atrophy, ulcers and other symptoms, the time for cancer might be relatively fast.
