The clinical manifestations of patients with gastric cancer vary somewhat depending on individual circumstances, and there are some differences in symptoms between patients with early-stage gastric cancer and those with mid- to late-stage gastric cancer.
Most patients with early gastric cancer do not have obvious clinical symptoms, which are insidious and not specific enough to identify, and can also persist for a long time, such as nausea, vague pain, loss of appetite, upper abdominal distension, etc. A few patients with ulcerative early gastric cancer can also have some ulcer-like symptoms, including acid reflux and rhythmic pain.
The symptoms of gastric cancer are difficult to determine. Some patients have gastric cancer coexisting with some benign lesions, such as chronic atrophic gastritis, peptic ulcer, etc. Cancer occurs in these benign gastric diseases, and the symptoms of these benign gastric diseases persist for a long time or recur, which can make patients relax their alertness to gastric cancer and thus miss the time of diagnosis.
Usually, stomach diseases do not attract enough attention from patients, and only when the growth of the tumor affects the stomach function will patients show more obvious symptoms, but these symptoms are rather lacking, specific, and difficult to determine whether they are caused by stomach cancer. The first thing you need to do is to have a surgical resection, and some patients need post-operative radiotherapy and chemotherapy.
