Procedures used to detect benign stomach tumors and polyps include imaging tests, endoscopies and biopsies, according to Mayo Clinic. Imaging tests, such as computerized tomography scans and barium swallows, are non-invasive methods to test for stomach tumors.
An endoscopy entails the insertion of a thin tube into the patient's stomach via the throat, details Mayo Clinic. The doctor uses a tiny camera inserted into the tube to check for tumors. If the doctor discovers suspicious areas during the endoscopy, he performs a biopsy to remove tissue from those areas, and then the tissue undergoes analysis.
Also known as gastric polyps, stomach polyps are rare, and most are not cancerous, explains Healthline. A doctor typically orders a biopsy when he suspects a stomach polyp to confirm the polyp is not cancerous. Symptoms of a gastric polyp include nausea, bleeding tenderness, vomiting and pain, although most people do not experience any symptoms.
The treatment for stomach polyps depends on the polyp size, location, quantity and whether or not they are cancerous, notes Healthline. Treatment is not necessary for all polyps, although doctors remove some as a preventive measure against developing cancer in the future.
Treatment options for stomach tumors include surgery, radiation therapy, chemotherapy and targeted drugs, advises Mayo Clinic. Sometimes doctors use multiple treatments. For example, doctors sometimes use radiation therapy prior to surgery to shrink the tumor, making it easier to remove.
