Radiotherapy market seen doubling to $18.91B by 2035

Market Research Future projects the global radiotherapy market will grow from $9.09 billion in 2025 to $18.91 billion by 2035, powered by rising cancer cases, faster treatment technologies and AI-driven planning. The outlook points to continued fleet upgrades, stronger demand in outpatient settings and expanding adoption of precision radiation systems worldwide.

Why it matters: - The radiotherapy market is expected to nearly double by 2035, signaling sustained demand for cancer treatment capacity worldwide. - Growth is tied to the rising cancer burden, technology upgrades and broader use of AI in treatment planning. - The shift matters for hospitals, equipment makers and payers because more care is moving toward faster, more precise and more outpatient-friendly radiation protocols.

Between the lines: - The market is shifting from hardware-led spending to a subscription-like model that includes software, service contracts and remote diagnostics. - Shorter hypofractionated treatment courses are freeing up machine time, which can raise patient throughput without expanding physical footprint. - The rise of AI and adaptive planning is also making software more valuable to vendors and more central to procurement decisions. - The strongest growth is coming from technologies and settings that reduce cost per treatment and improve access, especially in outpatient and emerging-market care.

What's next: - Market Research Future expects emerging-market expansion to continue through refurbished equipment bundles, blended finance and service-heavy procurement. - Compact particle therapy systems could move toward price parity with two-vault photon builds before 2032. - Software-defined capacity expansion, outcomes analytics and radioligand therapy are expected to create new growth lanes through 2035. - Vendors are likely to keep competing on installation speed, uptime, adaptive planning and recurring software revenue.
