Which two places will show abnormalities in the early stage of gastric cancer

In the early stages of gastric cancer, two common abnormal manifestations are mainly digestive system abnormalities and weight changes. They are as follows:

1. Abnormal digestive system: In the early stage of gastric cancer, patients may experience mild pain or bloating in the upper abdomen. This pain often has no clear pattern and is easily ignored. When cancer cells stimulate the stomach, it will cause pain, usually dull pain, and may gradually worsen. Ordinary stomach pain attacks usually follow a certain pattern. For example, the pain of gastritis or gastric ulcer often occurs one hour after eating, while the stomach pain caused by gastric cancer may be irregular and continuous. In the early stage of gastric cancer, patients may experience unexplained loss of appetite, lose interest in food, and feel tasteless even if they eat reluctantly. This loss of appetite may be accompanied by a feeling of bloating, leading to a decrease in food intake. Some gastric cancer patients may also experience gastrointestinal dysfunction in the early stage, manifested as diarrhea or constipation. The number of bowel movements will increase significantly during diarrhea, while constipation may be related to the chemotherapy drugs used in the treatment of gastric cancer and their toxic and side effects.

2. Weight changes: Since gastric cancer affects digestive function and leads to poor nutrient absorption, patients may experience weight loss. This weight loss is usually accompanied by symptoms such as fatigue and weight loss, which is an important early warning sign of gastric cancer.

Other symptoms may also appear in the early stages of gastric cancer, such as anemia, vomiting blood, black stools, etc., but these symptoms are relatively rare. The early symptoms of gastric cancer are often non-specific and can be easily confused with benign diseases such as chronic gastritis and gastric ulcers. When the above abnormal manifestations appear, you should seek medical attention in time for appropriate examinations to confirm the diagnosis and take appropriate treatment measures.

The two main abnormal manifestations of early gastric cancer are abnormalities in the digestive system and significant changes in weight. Although these abnormal manifestations are not specific, they are still important clues to the possibility of gastric cancer. Timely medical treatment and comprehensive examinations are the key to early detection of gastric cancer.
