Protons extracted from hydrogen atoms, or carbon ions are accelerated up to 70% of the speed of light.

This energy  is  concentrated  directly  on  the  tumor  while  minimizing  radiation  dose  to surrounding healthy tissue. Particle therapy improves the quality of life for cancer patients since the patient experiences no pain during treatment and the procedure has very few side effects compared to that of traditional radiotherapy. In most cases, patients can continue with their normal daily activities while undergoing treatment.
