The aim of cancer treatment is either to completely destroy all the tumour tissue in order to achieve long-term remission, or to reduce the size of the tumour, lessen tumour-related symptoms and prevent complications.

Often two or three established therapies are combined in order to destroy not only the tumour, but also the tiniest tumour fragments and individual tumour cells, which improves the chances of the treatment’s success and reduces the risk of the cancer returning.
