How Robotic Arms Are Saving Lives: Global Radiotherapy Insights

 Introduction

In the era of precision oncology, robotic radiotherapy is emerging as one of the most advanced, non-invasive cancer treatment modalities globally. With the global robotic radiotherapy market projected to grow from USD 1.45 billion in 2025 to USD 4.05 billion by 2035, this transformative field is being propelled by AI-driven planning, real-time tumor tracking, and breakthrough technologies like CyberKnife, MR-guided robotics, and adaptive radiotherapy.

What Is Robotic Radiotherapy?

Robotic radiotherapy is an ultra-precise treatment method where radiation beams are guided by robotic arms and image-guided technologies to directly target tumors, while sparing surrounding healthy tissue. Unlike traditional radiotherapy, which may involve rigid headframes or high radiation spillover, robotic systems like CyberKnife offer sub-millimeter precision, real-time motion tracking, and exceptional patient comfort.
