Gastric mucosal ulcer combined with anemia is not necessarily cancer. Gastric mucosal ulcer may affect the absorption of various nutrients, or lead to anemia when combined with chronic gastric bleeding, which is a common clinical symptom. However, for patients with cancerous lesions of the stomach, symptoms such as loss of appetite, fatigue, weight loss, etc. may occur in the early stage, but they are mostly characterized by irregular stomach pain. Therefore, it is not possible to judge whether one is suffering from cancer purely on the basis of gastric mucosal ulcer combined with anemia. For patients with gastric mucosal ulcer combined with anemia, it is recommended to undergo gastroscopy, pathological biopsy and other related examinations to determine whether they have cancer or not, and according to the results of the examination, treat the symptoms under the guidance of doctors.
