Cryotherapy using liquid nitrogen may have a role in the treatment of dysplasia and early gastric cancer, researchers have found.

Using techniques such as argon plasma coagulation and radiofrequency ablation also can be challenging because treating larger areas of tissue increases the risk for bleeding and ulceration.
