Shorter EBRT course works well for epithelial disease
By Cynthia E. Keen
As the sun-worshiping baby boomer generation ages throughout the world, the incidence of epithelial cancer is increasing. For patients with this skin disease, electron beam radiation therapy (EBRT) provides an excellent alternative to surgery, according to a new study published online in Radiotherapy and Oncology.
