Stomach cancer can be diagnosed by heart disease.

Gastric cancer can be diagnosed by three items of gastric cancer, serum tumor markers, gastroscopy, gastric histopathological biopsy, etc. The three items of gastric cancer include serum pepsinogen I, serum pepsinogen II and serum gastrin 17, which can reflect gastric atrophy and help to stratify the risk of gastric cancer. Serum tumor markers include carcinoembryonic antigen, cancer antigen CA19 -9, etc. These tumor markers are also helpful for the diagnosis of gastric cancer. In addition, abnormal gastric masses can be found through gastroscopy, and pathological biopsy can also be taken under gastroscope after abnormal masses are found, and gastric biopsy is the gold standard for diagnosis of gastric cancer.
