Tucked in a corner of the MedStar Georgetown University Hospital campus is the country’s 28th proton therapy center, which is set to begin treating patients this month. It is a small but state-of-the-art system designed to attack tumors more quickly than its predecessors in proton therapy, a precise type of radiation treatment that spares healthy tissue. Twenty-four more centers are under construction or in development, including one at D.C.’s Sibley Memorial Hospital that is scheduled to open in late 2019. (Berkowitz and Steckelberg, 3/1)

Middle Tennessee residents will soon have a new option for an innovative cancer treatment. Knoxville-headquartered Provision Healthcare is opening its second proton therapy center in the state, across from the Williamson County Medical Center in Franklin. The center will feature the ProNova system, the company's newest iteration of proton beam therapy that treats several types of cancers.
