This type of tumour is the only time in brain tumour surgery that you have to remove the tumour ‘en bloc’ – in a single piece – since if you enter the tumour you will be instantly faced by torrential bleeding. With all other tumours in brain surgery you gradually ‘debulk’ it, sucking or cutting out the inside of it, collapsing it in on itself, away from the brain, and thus minimizing damage to the brain.
