SIH opened their new Cancer Institute in Carterville for a open house on Friday.
Dozens of people showed up for the ribbon cutting and to get a first look at the 43,000 square foot facility.
SIH started planning the institute in 2010 and the project cost 24.5 million and took 15 months to build.
One of the highlights of the tour is the new linear accelerator machine for radiation treatment.
Two new features of the machine is the ability to do soft body stereotactic and soft body radio surgery.
