Technical advances can lead to benefits for women, for instance marking areas most at risk of relapse to allow targeted radiotherapy, and using a small number of high dose radiotherapy fractions to more effectively treat breast cancer, resulting in an improved chance of the patient remaining free from future relapses.

Prof. Yarnold goes on to explain that the patients that will respond best to radiotherapy can now be identified in advance and briefly addresses the viability of proton beam therapy.
