What are the symptoms of gastric cancer

What are the symptoms of stomach cancer?

Early gastric cancer usually has no specific symptoms. Some patients may experience upper abdominal discomfort, loss of appetite, and weight loss, which are easily ignored by patients. Most patients with early gastric cancer have no obvious symptoms. Few people experience nausea, vomiting, heartburn, acid reflux, and other upper gastrointestinal symptoms. That is, the original epithelium in the stomach is replaced by the epithelium similar to that in the intestine. Intestinal metaplasia is divided into mild, moderate, and severe, and dysplasia will also occur on this basis.

How to diagnose gastric cancer in pathology?

Gastric cancer patients must undergo endoscopic biopsy before surgery to clarify the patient's condition and pathological classification, especially for early diagnosis of gastric cancer, to provide a basis for surgical planning. However, endoscopic biopsy materials have great limitations, namely, they cannot accurately obtain all pathological tissues. Postoperative pathology solves this problem. Based on each pathological classification, stage and its genetic surface results, the surgical effect and patient prognosis are preliminarily evaluated, providing clinicians with new suggestions for follow-up treatment.

Accurate pathological diagnosis of gastric cancer is a comprehensive means of diagnosis, classification, characterization, treatment guidance and prognosis judgment through various examinations. Pathological diagnosis is the gold standard for gastric cancer diagnosis. Gastric tissue biopsy requires gastric tissue biopsy, cutting into wax blocks, then staining and observing the shape of cells under a microscope.

How long does stomach cancer surgery take?

Normally, the operation takes about two to four hours, and you need to stay in the hospital for about 10 days after the operation before you can be discharged. The specific situation depends on the individual's physical recovery. Some people recover slowly and it takes a relatively long time, and they need to be re-examined after one month.

After surgery, you should have a regular diet, try to eat less spicy, pickled, and low-fiber foods, and eat some fresh fruits and vegetables that contain vitamins. If comprehensive treatment is needed, you can use chemotherapy or radiotherapy. It is still uncertain how long gastric cancer surgery will take.
