In the early stage of pyloric cancer, symptoms such as pain in the upper abdomen, nausea and loss of appetite may occur. Pyloric cancer belongs to a type of gastric cancer, which is a relatively insidious disease and usually can be caused by bad dietary habits, etc. Usually, patients can have no symptoms in the early stage, which is usually found through gastroscopy. With the development of the disease, some patients may experience stomach discomfort such as abdominal distension, mild anorexia, etc. With further development of the disease, some patients may experience severe pain in the stomach, acid reflux, and even digestive symptoms such as vomiting blood and blood in stool, and at this time, it is found that the tumor may have already reached the middle to late stage. It is recommended that gastroscopy should be performed routinely after the age of 50 to rule out gastrointestinal diseases such as pyloric cancer. Once pyloric cancer is detected, regular treatment can be carried out at an early stage to achieve a higher cure rate, but for patients with middle and late-stage pyloric cancer, although they have been treated by surgery, the healing process is not ideal, so they should try their best to have regular medical checkups to achieve early detection and early treatment.
