Brisbane doctors are celebrating the treatment of the 1000th cancer patient to undergo a non-invasive gamma knife technique since it’s introduction in 2015.

The Princess Alexandra Hospital is the only public hospital in the nation equipped with this technology, and one of only two of its kind in the country.

The machine uses cutting edge medical technology that focuses beams of gamma rays to precisely target tumours. The PA’s gamma knife recently underwent a $1.5 million upgrade, making it even easier to treat patients.
