What are the symptoms of gastric cancer? Pay attention to these points

Gastric cancer is a disease that is quite harmful to the human body. The main manifestations of this disease will change with the continuous development of the disease. The early symptoms mainly include abdominal distension, dull pain, hidden pain, nausea, loss of appetite, belching and weight loss. Late-stage gastric cancer involving the colon can often cause diarrhea and bloody stools. When the cancer grows, obstruction symptoms will appear, making it difficult for the patient to swallow. Antral cancer causes symptoms of pyloric obstruction.

Gastric cancer is a relatively slow process from the beginning of canceration of some cells in the stomach tissue to the clinical appearance of cancer symptoms and signs. This process is medically called "precancerous period". If the signs of cancer can be found in the early stage of gastric cancer and timely treatment is carried out, the prognosis of gastric cancer will be better. Therefore, understanding the symptoms of gastric cancer is conducive to early detection and early treatment. So, what are the symptoms of gastric cancer?
The main symptoms of gastric cancer are that as the disease progresses, the function of the stomach and the general condition gradually change. These symptoms are often non-specific, may appear from time to time, and may exist for a long time. They include upper abdominal distension, dull pain, nausea, loss of appetite, belching, and weight loss. Some early gastric cancers may also cause vomiting blood, black stools, or difficulty swallowing, and require medical treatment.
Loss of appetite or poor appetite: Loss of appetite and weight loss are the second most common symptoms of gastric cancer. Nearly 50% of gastric cancer patients have obvious symptoms of loss of appetite or poor appetite. Some patients restrict their food intake because eating too much will cause abdominal distension or abdominal pain. Unexplained anorexia and weight loss are likely to be the initial symptoms of early gastric cancer and need to be taken seriously. Patients with early gastric cancer generally have no obvious positive signs. Most patients have only deep tenderness in the upper abdomen in addition to a weak general condition.
The most obvious symptom of gastric cancer is abdominal pain: continuous severe pain may occur and radiate to the waist and back. A very small number of patients with perforated cancerous ulcers may also experience severe abdominal pain and signs of peritoneal irritation. Loss of appetite and weight loss: the absorption of cancer toxins can cause patients to become increasingly emaciated, weak, anemic, and malnourished, which often progresses and eventually manifests as cachexia.
The second most common symptom is nausea and vomiting. Vomiting blood and black stools occur when ulcers form on the surface of the tumor. Most of them are positive for occult blood in the stool. Some patients may have intermittent black stools, but some patients also seek medical treatment for a large amount of vomiting blood. Diarrhea: It may be related to low gastric acid. The stool may be mushy and even have diarrhea at dawn.
