What are the early symptoms of gastrointestinal cancer

Early symptoms of gastrointestinal cancer include abdominal pain, loss of appetite, weight loss, nausea and vomiting, and black stools. If these symptoms occur for unknown reasons, you should see a doctor as soon as possible.

In the early stages of the disease, patients often feel dull pain or fullness in the upper abdomen, which is especially obvious after eating. This abdominal pain may be aggravated by weight gain from food digestion, but it is easily confused with stomach disease or other digestive tract problems. As the disease progresses, patients may experience nausea, vomiting, and even persistent acid reflux symptoms, which is related to the compression of gastrointestinal cancer on the gastric emptying function. Weight loss is another important signal that cannot be ignored, which is usually accompanied by decreased appetite and long-term fatigue. Black stools or occult blood in the stool caused by gastrointestinal bleeding are also common manifestations, indicating damage to the digestive tract and need to be particularly vigilant. If the lesion is close to the esophageal opening, the patient may also have difficulty swallowing. If necessary, a gastroscopy, endoscopic ultrasound, or CT scan can be used for diagnosis.

In order to prevent and detect gastrointestinal cancer in time, it is recommended to maintain the habit of regular physical examinations, especially for people with chronic gastritis, gastric ulcers or family history of tumors. In addition, a healthy diet is the key. Eat less pickled and smoked foods, avoid smoking and drinking. Eating more fiber-rich fruits, vegetables and cereals can help protect gastrointestinal health. Once the above symptoms appear, do not take stomach medicine at will, and be sure to have a check-up under the guidance of a doctor to avoid delaying the diagnosis and treatment of the disease.
