Can anemia in gastric cancer determine the stage?

Can anemia in gastric cancer determine the stage?

1. Clinically, it is not possible to determine the specific stage of gastric cancer based on gastric bleeding. Gastric bleeding may occur in any stage of gastric cancer. Gastric bleeding can also be caused by other reasons, such as the more common gastric ulcer, rupture of esophageal varicose veins caused by severe liver disease, and tearing of the gastric cardia mucosa caused by severe vomiting, all of which can cause gastric bleeding in patients.

2. The staging standards for gastric cancer are mainly based on the depth of infiltration of the gastric cancer tumor, the size of the tumor, the status of lymph node metastasis, and the judgment of distant metastasis. Preoperatively, it is mainly based on physical examination and imaging data. Postoperatively, it is determined based on pathological examination and surgical exploration.

3. Malignant tumors often occur in gastric mucosal lesions. During the rapid growth process, insufficient blood supply will occur, leading to erosion, ulceration and bleeding on the surface of gastric cancer.

What are the early symptoms of early gastric cancer?

1. Some patients have gastric cancer coexisting with certain benign lesions, or gastric cancer develops on the basis of certain benign lesions, such as chronic atrophic gastritis, peptic ulcer, etc. The symptoms of these benign gastric diseases have existed for a long time or recurred, which makes it easier for patients and doctors to relax their vigilance against the disease and delay diagnosis.

2. There are generally no obvious symptoms in the early stages. A small number of patients may experience upper abdominal pain, excessive stomach acid, acid reflux, belching and other symptoms of gastritis, which are easily ignored by people, resulting in further deterioration of the disease.

3. Early gastric cancer refers to gastric tumors that invade the gastric mucosa and submucosa, regardless of the size of the tumor and whether there is lymph node metastasis.
