Proton therapy for lung cancer
Treatment that is synchronised with breathing for maximum precision on the tumour
Lung cancer is one of the most technically challenging tumours to treat with external beam radiotherapy: its proximity to the heart, spine and oesophagus, and its natural movement in response to breathing, limit the dose that can be delivered using conventional techniques.
Proton therapy addresses this issue by synchronising the proton beam with respiratory movement, enabling precise doses to be delivered directly to the tumour whilst minimising exposure to adjacent critical organs.
It is an option for almost half of all diagnosed lung cancers, including inoperable tumours. The Cancer Centre at the Clinica Universidad de Navarra, with facilities in Madrid, is a leading centre for the diagnosis and treatment of lung cancer.

Indications for proton therapy in lung cancer
- Small cell lung cancer
- Non-small cell lung cancer
- Recurrent lung tumours, in selected cases
Indications for other thoracic tumours:
- Mediastinal tumours (thymomas and sarcomas)
- Malignant mesothelioma
- Lymphoma
Why at the Clínica Universidad de Navarra
The Lung Cancer Unit at the Clinica Universidad de Navarra Cancer Centre is an internationally recognised centre of excellence in the diagnosis and treatment of lung cancer.

Reference Center
The Clínica Universidad de Navarra is an international reference center in the diagnosis and treatment of cancer, offering patients and their families access to an interdisciplinary approach to esophageal cancer.

A unique concept
First facility in Spain integrated in an Intrahospital Cancer Center, with all its assistance, academic and research support.

Advanced technology
As a highly complex center, we have the most advanced technology for the most accurate diagnosis in the shortest time possible.
The most precise radiation therapy for cancer
The Proton Therapy Unit’s technology allows the beam energy to be adjusted layer by layer, enabling the tumour to be targeted with maximum precision and the exact position of the tumour to be verified daily before each session — a particularly important consideration in lung cancer, where respiratory movement can displace the tumour during irradiation.
