Brief summary: To establish combined gastroenteroscopy screening and follow-up management for gastrointestinal tumors, explore and evaluate the feasibility and health economic benefits of combined screening for esophagus, stomach and colorectal cancer

Detailed description: group one: The screening population will undergo gastroscopy, colonoscopy, fecal occult blood test (FIT), Helicobacter pylori (HP) antigen test, ring finger protein 180 (RNF180) and SEPTIN9 gene methylation test, and investigation of risk factors, including past disease history, alcohol drinking history, smoking history, tea drinking history, family history of cancer, marital and reproductive status, and dietary habits.

group two: The screening population will undergo investigation of risk factors, a fecal occult blood test (FIT), and a stool test for Helicobacter pylori (HP) antigen. If a stool occult blood test or H. pylori antigen is positive after testing, RNF180 and SEPTIN9 gene methylation testing will be scheduled. If the gene methylation test is positive, a colonoscopy will be scheduled.

Group one's control（Spouse or sibling of group one);group two's control（Spouse or sibling of group one): Only the risk factors will be investigated, including previous disease history, drinking history, smoking history, drinking history, family history of malignant tumor, marriage and childbearing status, eating habits, etc.

Finally, 10 years follow-up will be conducted to observe the outcome
