Can brain tumours also be tested with a blood sample?

No, due to the blood-brain barrier, tumour cells cannot enter the bloodstream. This means that we cannot obtain and isolate any tumour cells from the blood sample.

Is it possible to measure circulating tumour cells (CTC) in patients with lymphoma or leukaemia?

Yes, patients with lymphoma or leukaemia can use an RGCC test to measure the number of circulating tumour cells (CTC) they have.

Which test is the most comprehensive test?

The most comprehensive test is the “Onconomics Plus” test. This provides information on the sensitivity or resistance of the patient’s tumour cells to certain cancer drugs and shows options for targeted therapy or an alternative treatment method with organic substances. The test also contains information about the development of the tumour and its potential by identifying epigenetic tumour markers relevant for the therapy, which are crucial for the correct therapeutic approach.

How do online consultations work?

Online consultations will give you the opportunity to speak to any member of the RGCC Network at a time and place that is convenient to you. You will be able to choose from a shortlist of clinicians who best suit your needs.

Will online consultations take place via Zoom, Skype, or another method?
