A computer algorithm which helps radiographers interpret ultrasound images could improve radiotherapy treatment for patients with prostate cancer, a new study suggests.

A lower total dose of radiotherapy delivered in fewer but larger doses is as safe in the long term as breast cancer radiotherapy courses giving multiple small doses, according to the final results of a 10-year study.

Scientists have shown that therapies which combine heat and radiation have a different effect on lab-grown mini tumours than they do on lab-grown cancer cells grown in a more traditional way in a two-dimensional layer.
