Introduction
The distinction between benign and malignant gastric polyps is mainly reflected in pathological characteristics, imaging findings, and clinical symptoms. Benign gastric polyps are non-cancerous tumor lesions and are relatively common. They may gradually grow over time but do not infiltrate or destroy adjacent tissues. Malignant gastric polyps are cancerous lesions that grow rapidly and can invade and damage surrounding healthy tissues.

Gastric polyps can be differentiated into benign and malignant types based on pathological characteristics, imaging findings, and clinical symptoms.

1. Pathological Characteristics

Benign gastric polyps are non-cancerous lesions and are relatively common. They may gradually grow over time but do not invade or destroy surrounding tissues. Malignant gastric polyps are cancerous lesions that tend to grow rapidly and can infiltrate and damage healthy tissues.

2. Imaging Findings

During medical imaging examinations such as computed tomography (CT) or magnetic resonance imaging (MRI), benign gastric polyps typically show clear, well-defined borders between the polyp and adjacent healthy tissue. In contrast, malignant polyps often exhibit blurred or indistinct boundaries, with signs of infiltration or fusion with surrounding tissues.

3. Clinical Symptoms

Patients with benign gastric polyps may experience symptoms such as stomach pain, heartburn, and decreased appetite. However, in addition to these symptoms, malignant gastric polyps are commonly associated with signs of gastrointestinal bleeding, including hematemesis (vomiting blood), hematochezia (blood in stool), and melena (black, tarry stools).

      A definitive diagnosis to differentiate between these two conditions requires a medical evaluation and diagnostic testing at a healthcare facility.
