How does it work?

Proton therapy allows radiation to be more precisely targeted on the tumor.

The most precise radiation therapy for cancer treatment

Proton therapy is based on a different type of radiation from conventional radiotherapy

Whereas radiation therapy is based on a beam of high-energy X-rays (photons), proton therapy uses a beam of high-energy accelerated particles (protons), meaning that radiation can be more precisely targeted on the tumor.

This is due to the protons’ physical characteristics because, given their mass, their trajectory does not change as they pass through the body to the lesion. These particles are able to deposit most of their energy inside the tumor, the selected treatment field; in addition, as a result of their braking effect, they do not radiate beyond this braking point (Bragg peak), unlike photons.

Proton therapy sessions last an estimated 25 minutes. Most of the session is spent on positioning and image-guided verification of the patient treatment field. Irradiation time is, in most cases, under one minute.
