Cancer Center

UW Cancer Center Riverview is the leader in bringing innovative, complete cancer care and treatment to central Wisconsin. Our center is an affiliate of the UW Carbone Cancer Center at the University of Wisconsin in Madison. We offer our patients world-class cancer care in a beautiful, comforting setting that’s close to home.

UW Cancer Center Riverview offers cancer patients complete, leading-edge cancer care. Convenient care and treatment includes oncology exams, diagnostic lab work and imaging scans, chemotherapy, radiation therapy, surgery, clinical trial participation, and more.

Leading-edge TomoTherapy Radiation Therapy

UW Cancer Center Riverview was the first cancer center in central Wisconsin to offer helical TomoTherapy, a sophisticated and effective image-guided and intensity-modulated radiation therapy. Invented by scientists and oncologists at the world-renowned UW Carbone Cancer Center in Madison, TomoTherapy uses CT scanning plus highly targeted beams delivered from all possible angles to attack tumors and cure cancers with unprecedented precision. Because each beam angle includes a relatively small amount of radiation, the body's healthy tissue is unharmed, helping to minimize any pain or side effects from the treatment.
