Real-time organ motion tracking is now available in 65% of new systems, reducing dosage exposure to nearby organs by up to 15% per session. The trend toward ""flash"" therapy is gathering momentum. As of 2024, at least 5 global centers are running preclinical studies on ultra-high dose rate treatments intended to minimize normal tissue damage. This research is particularly relevant for radioresistant tumors and pediatric patients. Furthermore, integration of MRI guidance in proton therapy began pilot testing in 2023 in European research hospitals, further advancing treatment accuracy. Investment in turn-key proton systems by hospitals has increased. In the past two years, over 25 new hospital-based centers have committed to compact proton therapy solutions. Most installations favor single-room models to reduce cost and construction time. The average set-up time for a new single-room center has been reduced to 18–24 months. The market is also driven by expanding insurance reimbursement. In the United States, 95% of private insurers now cover pediatric cases, while adult coverage is expanding in select regions. Similarly, in Canada and several European countries, public insurance provides full or partial proton therapy reimbursement for high-need cases, particularly pediatric, head-and-neck, and spinal tumors.

Proton Therapy Market Dynamics

DRIVER

Rise in Complex and Pediatric Cancer Cases

Global cancer incidence reached over 19 million new cases in 2023, with approximately 400,000 pediatric oncology patients diagnosed annually. Proton therapy centers treated more than 370,000 patients by 2024, including nearly 74,000 pediatric cases (~20% of total), demonstrating its efficacy in delivering minimized-dose treatment for sensitive populations with critical tumors.

RESTRAINT

High Installation and Operational Costs

Building a multi-room proton facility requires 6,000–8,000 m² of space. Single-room compact systems still require 1,200–1,500 m² and cost over $100 million each.
