Maybe, but not everywhere — and it should never be assumed. Gamma Knife is a specific machine (one brand, Elekta) that delivers stereotactic radiosurgery: the National Cancer Institute (NCI) describes this as focused, high-energy beams that treat small, well-defined tumors in the brain and central nervous system, with no incision, usually in a single session. A hospital that offers standard radiation does not automatically operate a Gamma Knife unit, so whether a particular Istanbul or Turkey center has one must be confirmed directly with that named, state-authorized facility — not inferred from a general 'we treat cancer' claim. OncologyIstanbul is not a hospital and operates no radiosurgery unit; we can help you organize your reports and check any facility's authorization, but we will never claim a treatment is available when it may not be.
