Clinique Pasteur

The Radiotherapy Centre

The Ris-Orangis Radiotherapy Centre (CRRO) is unique in the Essonne region.

Located on the same site as the Clinique Pasteur, it forms the Essonne Cancer Centre, along with the clinic's chemotherapy day hospital.

The CRRO cares for patients requiring radiotherapy treatment for cancer.

It offers patients cutting-edge radiotherapy techniques, thanks to a team of qualified and specialised doctors, medical physicists and manipulators.

Modern, high-performance equipment enables oncologists to offer the most appropriate treatment for each patient, guaranteeing high-quality care and the best possible quality of life.

The CRRO is a member of the Essonne "Essononco" cancerology network, and is also a member of the departmental inter-establishment 3C.
