Can stomach cancer and intestinal cancer be detected

Colorectal cancer generally refers to colorectal cancer. Blood tests can be used to preliminarily screen for gastric cancer and colorectal cancer, but they cannot diagnose whether you are sick.

If you have gastric cancer, the levels of blood cells, hemoglobin and coagulation factors will decrease, and the level of tumor marker CA72-4 will increase significantly. These conditions can be observed in blood tests, but these phenomena cannot be diagnosed as gastric cancer. Electronic gastroscopy is needed to remove some tissue for pathological examination for diagnosis. If you have gastric cancer, you need to cooperate with the doctor for surgical resection.

If you have colorectal cancer, you may find that your red blood cell and hemoglobin levels will decrease, you may also have anemia, and the level of tumor marker CEA will increase, so blood tests can be used to preliminarily screen for colorectal cancer. However, if you want to diagnose whether you have colorectal cancer, you also need to cooperate with the doctor to perform colonoscopy, pelvic CT examination and pathological examination. Surgical resection can be used for early treatment, and radiotherapy, chemotherapy and other methods are generally used for intervention in the middle and late stages.

If you feel any physical discomfort, it is recommended that you go to the hospital for examination as soon as possible and follow the doctor's advice for symptomatic treatment.
