What is proton therapy?

Proton therapy’s unique properties offer cancer patients great benefits.

Proton therapy is the most precise form of external radiotherapy available, ensuring better distribution of the exact dosage (dosimetric precision, i.e. exact radiation dose and location) and therefore less irradiation of healthy tissues and lower risk of unnecessary radiation-induced effects (secondary tumors).

Its application represents a major advance in clinical treatment based on the dosimetric benefit obtained, which is superior for protons compared to any other form of high-precision radiotherapy available.

Proton therapy benefits

Icono naranja señal de toxicidad

Lower toxicity

Avoids short- and long-term adverse effects on healthy tissues

Icono naranja precisión radiación

Greater precision

A high-energy beam deposited in the exact treatment location

Icono naranja control

Greater control

Minimizes unnecessary scatter radiation to healthy surrounding tissues


The most precise radiation therapy for cancer

The protons deposit their energy within successive tumor layers extremely quickly, destroying them and then repairing them through normal scar tissue.
