(Gastric Polyps)

Stuh-muk Pall-ups


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:

  • Hyperplastic—most common
  • 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:

  • Infections
  • Health conditions

Some stomach polyps may be caused by problems with your genes.
