【Patient question】I have been discharged from the army for more than ten years, but I still have the habit of exercising, I will run 10 kilometers every night, and I feel healthy, that is, my stomach is a little big. However, middle-aged people have small bellies, and I don't care, but recently my stomach has become bigger and bigger, like pregnancy. Later, when I went to the hospital to check the CT and gastroscopy, the doctor said that there was ascites in the stomach, which was advanced stomach cancer. I don't understand, before there was very little gastrointestinal discomfort, appetite is normal, how to get stomach cancer?

【Doctor's answer】 Many gastrointestinal tumors do not have obvious external symptoms in the early stage, and a good appetite does not equal gastrointestinal health. The occurrence of stomach cancer is the result of a combination of factors, genetics, smoking and drinking alcohol or poor diet (high oil, high salt, binge eating, etc.) can lead to stomach cancer.
