PHOENIX -- One of the country's top cancer research centers is one step closer to opening a cutting-edge treatment facility in Phoenix.
On Thursday construction crews put the final steel beam into place, where the Mayo Clinic will operate with proton- beam therapy.
"It's a $182 million investment in a laserlike beam of matter," said Dr. Wyatt Decker, CEO of Mayo Clinic Arizona. "Protons go deep into the human body, release very little energy until they hit their target, then they release a burst of energy that kills tumor cells."
The facility is approximately 165,000 square feet, and will be connected to the cancer center's current home on Mayo Boulevard.
The facility opens in 2016.
