Is rac sign gastric cancer

Clinically, RAC sign is not gastric cancer, but a manifestation of gastric mucosal vascular abnormality. However, patients are still advised to seek medical attention in a timely manner and receive targeted treatment under the guidance of a physician.

The RAC sign is mainly related to insufficient gastric acid secretion, which may affect the digestion and absorption function of the gastrointestinal tract, causing gastrointestinal bloating, diarrhea, constipation and other symptoms. When a partial RAC sign is found in the gastric body during gastroscopy, it means that the blood vessels in the gastric mucosa are abnormal. Under normal circumstances, the shape and distribution of these tiny blood vessels are regular, but when stimulated or infected, such as gastritis caused by Helicobacter pylori, the appearance of these blood vessels may become irregular or even disappear completely. This is due to changes in the submucosal blood vessels caused by inflammation.

RAC sign is not equivalent to gastric cancer. Gastric cancer is a malignant tumor, and its formation is a complex process involving gene mutation and long-term uncontrolled cell growth. Gastric cancer may cause a variety of changes in the gastric mucosa, including changes in blood vessels, but this is only one manifestation that gastric cancer may cause, not a direct sign of gastric cancer itself.

For patients with RAC syndrome, active treatment and regular check-ups should be carried out to reduce the risk of gastric cancer. At the same time, maintaining good living habits and eating habits is also an important measure to prevent gastric cancer.
