Can Recurrent Gastric Ulcers Turn Into Cancer?

Gastric ulcers, if left untreated or if they recur frequently, may carry a risk of becoming cancerous over time. While peptic ulcers in the stomach can potentially undergo malignant transformation, duodenal ulcers located in the first part of the small intestine typically do not have this risk.

One of the key signs that may indicate a gastric ulcer is persistent or recurring pain in the upper central abdomen, especially after eating. This is different from duodenal ulcers, which often cause pain during periods of hunger or at night, usually felt in the upper right quadrant of the abdomen.

If you experience repeated episodes of post-meal abdominal pain, it's crucial to seek medical attention promptly. A gastroscopy, or endoscopic examination of the stomach, is one of the most effective diagnostic tools for identifying ulcers. During this procedure, doctors can visually inspect the stomach lining and assess the size, depth, and appearance of any ulcer, including whether it has developed a crater-like or "volcano" shape—often a concerning sign.

In cases where an ulcer is suspected, taking a biopsy during the endoscopy is essential to rule out malignancy or confirm the presence of cancerous changes. Early diagnosis and targeted treatment play a critical role in preventing complications and improving long-term outcomes.

Therefore, while not all gastric ulcers become cancerous, regular monitoring and timely intervention are highly recommended for individuals with chronic or recurrent symptoms.
