Gastroscopic Differences Between Gastric Cancer and Polyps

During a gastroscopic examination, there are clear distinctions between gastric cancer and polyps. Here's a detailed breakdown of the differences:

Gastric Polyps:
Gastric polyps typically appear as small, raised growths on the mucosal surface. They are often smooth in texture and resemble small peas or mung beans, usually measuring between 0.5 and 2 cm, with most being less than 1 cm in size. Polyps can be classified into two types: neoplastic and non-neoplastic. Neoplastic polyps carry a higher risk of malignancy, while non-neoplastic polyps are generally benign. If a neoplastic polyp is detected during gastroscopy, it is usually recommended to remove it endoscopically to prevent potential cancer development.

Gastric Cancer:
In its early stages, gastric cancer may also present as a raised lesion on the mucosal surface. However, unlike polyps, the surface of these lesions is often irregular and may show signs of erosion or easy bleeding upon contact. As the cancer progresses, larger and more advanced tumors may appear in various forms, such as cauliflower-like or ulcerative lesions. While gastroscopy can help differentiate these growths, a definitive diagnosis requires histopathological analysis.

Key Diagnostic Differences:
One of the main differences between the two is the surface appearance during endoscopy. Polyps tend to be smooth and well-defined, whereas cancerous lesions are often rough, irregular, and may bleed easily. Additionally, the size and shape of the lesion can offer important clues to the underlying condition.

In summary, while both gastric polyps and gastric cancer may initially appear similar during gastroscopy, careful visual inspection and biopsy results are crucial for accurate diagnosis and appropriate treatment planning.
