Gastric Ulcers and the Risk of Cancer: Understanding the Timeline

It may take several years or even more than a decade for a gastric ulcer to potentially progress into cancer. However, there are important factors to be aware of when considering this risk:

Chronic Inflammation Increases Cancer Risk

One of the key contributors to cancer development in gastric ulcers is long-term inflammation. This often stems from persistent Helicobacter pylori infection, which can cause recurring ulcers. Continuous irritation from this infection may increase the likelihood of malignant transformation over time.

Some Ulcers May Be Cancerous From the Start

In certain cases, what appears as a benign gastric ulcer may actually be an early form of stomach cancer presenting in an ulcer-like form. During endoscopic examination, if an ulcer appears large, irregular in shape, or covered with a dirty-looking coating, it should be closely monitored—even if initial biopsy results appear negative for cancer.

Timely Follow-Up is Crucial After Initial Treatment

Medical professionals recommend a follow-up exam shortly after treatment, especially for suspicious ulcers. Repeat biopsies may be necessary to confirm a definitive diagnosis and rule out malignancy.

Being vigilant about gastric ulcer symptoms and undergoing regular medical evaluations can significantly improve early detection and outcomes. If you have a history of chronic ulcers, consult your doctor to assess your individual cancer risk.
