Discovering and treating tumors before they spread throughout the body is key for cancer patients to achieve positive outcomes. When tumor cells spread, which is known as metastasis, they can take over other organs and lead to death. Oral and esophageal carcinomas, or mouth and throat cancers, frequently metastasize to the lymph nodes. Unfortunately, there are currently no therapies that are specific to treating these particular cancers. Now, researchers at Tokyo Medical and Dental University (TMDU) identified several drugs that can possibly be used to treat oral and esophageal carcinomas.
