Referring clinicians and the Netherlands Cancer Institute

The Netherlands Cancer Institute is a secondary and tertiary care center for cancer patients.
If you suspect breast cancer, prostate cancer, skin cancer, or intestinal cancer, you can refer your patient to our care. We have set up a special general practitioner outpatient clinic, where patients can be seen within one day after referral.

We offer rapid diagnostics for many types of cancer. Our rapid diagnostics include additional relevant tests and consultations with all specialists involved. All patient cases will be discussed during a multidisciplinary team meeting. Afterward, patients are free to pick their preferred hospital for treatment.

Referring your patient

Please note: as of March 31, 2022, we will no longer be using fax to send or receive messages. We would like to ask you to use the secure e-mail platforms Zorgmail or Zivver instead, or use our digital referral form.

Please fill out the referral form in its entirety and attach all relevant documentation, so we can plan an appointment to see the patient at the appropriate clinic.

Once the form has been filled out and submitted, our planning department will process it. The patient will receive an invitation to come to the clinic that is most suitable for their symptoms. Most of our clinics are tumor-specific and multidisciplinary. After the appointment, we will get back to you as soon as possible.


All general practitioners can use ZorgDomein to digitally refer patients to the Netherlands Cancer Institute. All information for our specialists can be submitted through ZorgDomein. Click here to visit ZorgDomein.
