Cancer Treatment Centers of America® at Southwestern Regional Medical Center opened its doors in 1991. In 2005, the hospital opened a new, 195,000 square foot patient-centered facility specially designed to meet the needs of patients and their family members. The state-of-the-art cancer hospital houses some of the most advanced diagnostic and therapeutic resources in cancer care, including the latest cancer treatments, world-class technologies, and supportive therapies—all under one roof. Each patient has his or her own multidisciplinary team of cancer experts skilled in fighting advanced and complex cancers. The modern, 195,845-square-foot hospital is Oklahoma's only major hospital totally focused on treating cancer. Like all CTCA cancer hospitals, the Tulsa facility provides an unsurpassed environment of healing and hope. We believe in providing the Mother Standard® of care, which means that we treat every patient as if they were our own mother, father, sister or brother.
