This is absolutely incredible.
According to FOX5, "An orchestra violinist played her instrument during an operation to remove a brain tumor at King’s College Hospital in London on Jan. 31, ensuring the musician’s hand movement and coordination were not accidentally damaged by surgeons. Dagmar Turner, 53, was diagnosed with a slow-growing tumor in 2013 after she had a seizure during a symphony, according to a King’s College Hospital press release. Turner had radiotherapy but later turned to surgery after the tumor had “grown and become more aggressive” in 2019."
Watching the video below my mind is blown at the fact that she's continuing to play so well, knowing that the surgeons are not only operating, but operating correctly.
