It is possible to get stomach cancer with normal tumor marker 199. Tumor marker 199 is to check whether there are malignant tumor cells in liver and gallbladder as well as pancreas, stomach, colon and rectum, but if tumor marker 199 is normal, it does not exclude early gastric cancer, and it is better to go to regular hospitals in time and take the examination through gastroscopy to determine whether there are malignant tumors in the stomach. Therefore, normal tumor marker 199 is not necessarily able to completely exclude gastric cancer, but also need to confirm the diagnosis of the condition through further examination.
