Breakthrough Oral Cancer Treatment Shows Promise: Direct Immunotherapy Injection Reduces Lesion Size by 60%

USA: Researchers have found in a new study that direct injection of immunotherapy into precancerous oral lesions led to an average 60% reduction in lesion size, with over 80% remaining cancer-free at one year. Importantly, no dose-limiting or systemic immune-related toxicities were observed. This approach may reduce the risk of progression to cancer and help some patients avoid major, potentially debilitating surgery.
