Key cancer types targeted
Cancer treatment with protons is used when tumours are located near vital organs like the heart, lung, liver and oesophagus because protons do not pass through and into adjacent healthy tissue. It is used in cases where other forms of radiation may be less effective or the side effect risk is too high. Cancer types traditionally treated include cancers of the head and neck, eye, base of skull, brain, spinal cord, lung, gastrointestinal (GI) tract and prostate and breast.
Proton therapy is also considered beneficial and cost effective in paediatric cancers because it does not damage healthy growing bone and tissues. Therefore, children can grow and develop normally with a much lower risk of secondary tumours later in life.
