When the applicant for an authorisation including the mention of external radiotherapy and brachytherapy provided for in 2° of article R. 6123-86-1 is not a health establishment, this authorisation may only be issued or renewed if the facilities it uses to carry out its activity are located within the enclosure or in neighbouring buildings of a health establishment holding the authorisation provided for in article R. 6123-86.
The authorisation is subject to the conclusion of an agreement organising their cooperation in cancerology for the care of the patients they receive, for each type of practice for which they are authorised.
