The study is published...
There is currently a lack of reliable methods for distinguishing ductal carcinoma in situ (DCIS) that would never become symptomatic from DCIS that is likely to progress to life-threatening invasive cancer. Spurred by uncertainty about the optimal clinical management of DCIS, researchers have...
New research suggests that it is safe to limit radiation therapy to lymph nodes on only one side of the neck for lateralized tonsil cancer. In addition, the study findings show that primary tumor location, rather than the amount of lymph node involvement on the tumor side of the neck, drives the...
New research is showing that sparing the contralateral submandibular gland during radiation therapy in the treatment of locally advanced head and neck cancer is technically feasible and safe even in advanced-stage, node-positive disease and base-of-tongue lesions.
