Research institutes in Italy, such as those in Pisa and Florence, are exploring the potential of Quantum Cascade Lasers (QCLs) and high-energy diode systems for the next generation of cancer therapy.

These compact, high-power systems are being developed to create "very brilliant" X-rays and proton beams that can penetrate deeper into the body with less peripheral damage than traditional radiation. The goal is to create mobile therapy units that can be moved between hospital departments, making advanced "Extreme Photonics" treatments accessible to a wider population. This research represents the frontier of Italian medical physics, moving toward a future where light is the primary tool for both diagnosing and curing internal malignancies.
