5 million patients worldwide need radiosurgery for brain tumour yearly; less fewer than 10% receive it: John R. Adler

Around five million patients worldwide each year could benefit from radiosurgery for brain tumours and neurological disorders, yet fewer than 10% currently receive such treatment, according to John R. Adler, renowned neurosurgeon and professor at Stanford University. He was speaking at the launch of the ZAP-X Gyroscopic Neuro-Radiosurgery Platform at AIG Hospitals, Hyderabad, on Friday (March 6, 2026).

The ZAP-X system is designed exclusively for treating intracranial conditions and allows doctors to target tumours and abnormal brain tissue with highly focused radiation beams delivered with sub-millimetre accuracy. The technology enables treatment of brain tumours and several neurological disorders without open surgery, without incisions and typically as a day-care procedure.
