A stomach polyp is a growth in the lining of the stomach. There are many different types of polyps. The types are based on where they are and how they grow. Most of the polyps are not cancerous, but some can grow into cancer.
Common types of polyps:
Fundic gland—found in the upper part of the stomach
Adenoma—most likely to later become stomach cancer (least common type)
Stomach polyps often start because of injury or irritation of the lining of the stomach. This may happen with:
Stomach acid levels that are too high or too low
Some stomach polyps may be caused by problems with your genes.
Most stomach polyps are more likely to occur in older adults. Your chances of stomach polyps are also higher for:
