Two new NHS proton beam therapy facilities could offer treatment to 1,500 cancer patients a year when they open in the next few years.
The therapy – which is particularly helpful for children with rare and complex tumours – was highlighted with the case of Ashya King last year.
The five-year old’s parents took him abroad after doctors in the UK did not recommend it for his brain tumour.
Experts say the new centres will be “game-changing”.
The therapy allows precise targeting of certain tumours, increasing the success rates and reducing the risk of damage to surrounding tissues.
But it is not yet available in the UK – apart from one clinic to treat eye conditions.
On Wednesday, a ceremony at University College London Hospital (UCLH) – attended by Health Secretary Jeremy Hunt – marked the start of construction at one of the sites, due to open in 2019.
The other, at the Christie cancer centre in Manchester, will start taking patients in 2018.
