About Central Kansas Cancer Institute

external beam radiation therapy
Located in Manhattan Medical Center, Bldg E

At Central Kansas Cancer Institute (CKCI), we believe that every patient with cancer deserves to receive the best possible management to achieve cure, long-term tumor control and/or symptom relief. We are committed to providing all patients with the highest standard of quality care available in an environment where the healing of the whole person can take place through treatment that manifests deep respect for human life. It is the goal of each employee and the institute as a whole to treat each patient the way we would want a member of our own family treated.

CKCI provides external beam radiation therapy treatments for cancer. An important aspect of our mission is to work with the patient’s physicians and other healthcare professionals to coordinate the best comprehensive treatment plan. With 11 years in practice, our radiation oncology team has the experience and expertise to deliver quality care in a compassionate manner to all our patients. The majority of our staff has been together since the inception of CKCI, and as we grow, we add additional team members to complement the exceptional treatment already provided.
