Will stomach polyps develop into cancer?
Will stomach polyps develop into cancer? Do you know stomach polyps? Do you know what gastrointestinal polyps are?
Stomach polyps is a more stubborn disease, and gastric polyps are generally not easy to find, but the stomach is a relatively important organ. Once there is a problem, there will be endless troubles. Today, I will share the knowledge about gastric polyps with you.
Why do I get stomach polyps?
Stomach polyps generally occur in the antrum of the stomach, and a few can also be found in the upper part of the stomach, cardia and fundus. Pathologically, it is mainly divided into hyperplastic polyps and adenomatous polyps.
1. Hyperplastic polyp:
It is a polyp-like substance formed by inflammatory mucosal hyperplasia, not a real tumor. Polyps are small, generally less than 1.5cm in diameter, round or olive-shaped, pedicled or sessile, smooth surface, and may be accompanied by erosion.
A small number of hyperplastic polyps can develop dysplasia or adenomatous degeneration to produce malignant transformation, but the cancer rate generally does not exceed 1% to 2%.
2. Adenomatous polyps:
benign gastric tumors derived from the epithelium of the gastric mucosa. They are generally large in size, spherical or hemispherical, most have no pedicles, with smooth surfaces, and a few are flat, striped or lobed.
Histologically, it is mainly formed by surface epithelium, pit epithelium and glandular hyperplasia. Epithelial differentiation is immature and mitotic figures are more common. They can be divided into tubular, villous and mixed adenomas, often accompanied by obvious intestinal metaplasia and dysplasia.
This type of polyp has a high carcinogenesis rate, up to 30% to 58.3%, especially for those with tumor diameter greater than 2cm, villous adenoma, and grade III dysplasia.
Symptoms of stomach polyps
1. Upper abdominal pain, bloating, discomfort, nausea and vomiting may occur in a few. Patients with erosions or ulcers may have upper gastrointestinal bleeding, which is mostly manifested as positive fecal occult blood test or melena. Hematemesis is rare. The pedicled polyps located in the pylorus can break into the pyloric duct or duodenum, and show pyloric obstruction. Polyps may have difficulty swallowing when they grow near the cardia.
2. Abdominal pain: one of the common clinical symptoms, which can be acute or chronic. Its etiology is complex, mostly organic or functional. It is mostly caused by intra-abdominal organ lesions or caused by external organ lesions.
3. Nausea and vomiting: common clinical symptoms of nausea and vomiting. Nausea is often a prodromal sensation of vomiting and can also occur alone. It shows special discomfort in the upper abdomen, often accompanied by dizziness, blood pressure drop and other symptoms of vagus nerve excitement.
4. Upper abdominal discomfort: manifesting dull pain and abdominal distension and so on.
Experts point out that gastric polyps are very small, less than one centimeter long. Hyperplastic polyps are basically benign lesions. Only a small number of people can cause indigestion, abdominal pain and discomfort, as well as upper digestion. Dao bleeding can only be seen for a long time, and it can also become cancerous.
