Cancer treatment traditionally relies on surgery, radiation, and chemotherapy. For advanced or aggressive tumors, a multimodal approach targeting cancer on multiple fronts yields the best outcomes. Surgery removes the solid tumor and nearby lymph nodes, adjuvant radiation destroys microscopic cancer cells remaining in the surgical area, and chemotherapy targets cancer cells potentially circulating in the body.
Recent advances in robotic surgery and radiation therapy have enhanced precision and improved patient outcomes, making it essential for patients and caregivers to understand these innovations.
Robotic surgery is a state-of-the-art form of minimally invasive surgery that is transforming cancer care globally. Unlike traditional open or laparoscopic surgery, robotic platforms enable surgeons to operate with greater precision and flexibility in difficult-to-reach areas. The most commonly used robotic systems function as telemanipulators controlled by surgeons from ergonomic consoles that provide magnified 3D high-definition views. These systems translate the surgeon’s movements in real time, incorporating features like tremor filtration and motion scaling for delicate procedures.
Robotic surgery offers cancer patients numerous benefits, including less pain, minimal blood loss, reduced infection risk, smaller scars, shorter hospital stays, and faster recovery. Large studies confirm that cancer cure rates and long-term outcomes are comparable to conventional surgery. This approach is especially advantageous in cancers of the pelvis (prostate, cervix, endometrium, rectum), kidney, bladder, esophagus, lung, and throat.
While robotic surgery is currently more expensive due to equipment and maintenance costs, prices are expected to decrease with new players entering the market. Most health insurance plans in India now cover robotic surgery, following guidelines issued by the Insurance Regulatory and Development Authority of India in 2019.
India is seeing rapid growth in robotic procedures, recording a 53% increase in 2024 and becoming the fastest-growing market in the Asia-Pacific region. The sector’s value is projected to rise from $78 million in 2022 to $390 million by 2030. Future robotic systems will integrate artificial intelligence, improved ergonomics, and multi-quadrant access to reduce surgeon fatigue and complications, making robotic surgery a fast-emerging standard for minimally invasive cancer procedures.
Radiation therapy works by delivering high-energy X-rays to damage the DNA of cancer cells. Earlier radiation machines, while effective, lacked precision and often exposed healthy tissues to unnecessary radiation, causing side effects. Advances in imaging, computing, engineering, and physics have revolutionized radiation therapy, making treatments safer, faster, and more precise.
Image-Guided Radiation Therapy (IGRT) uses imaging before each session to target tumors accurately, compensating for internal movements such as breathing or organ shifts. Techniques like Intensity-Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) tailor radiation beams to tumor shapes, significantly reducing side effects in cancers of the head and neck, breast, brain, and prostate.
Stereotactic radiation, including Stereotactic Radiosurgery (SRS) for brain tumors and Stereotactic Body Radiation Therapy (SBRT) for lung, liver, and spine cancers, delivers high-dose, precise treatment in 1 to 5 sessions instead of the traditional 25 to 40. Often described as “surgery without a knife,” these methods spare surrounding healthy tissues.
Adaptive Radiation Therapy enables modification of treatment plans during sessions as tumors shrink or patient anatomy changes. The Magnetic Resonance Linear Accelerator (MR-Linac) combines real-time MR imaging with radiation delivery for precise adjustments, useful for tumors that move with breathing.
Beyond traditional X-rays, proton and carbon-ion therapies provide more selective radiation delivery, reducing long-term side effects, especially valuable in pediatric cases. Innovations such as FLASH therapy, robotic assistance, tumor-tracking systems, and digital “virtual patient” models are shaping the future of radiation oncology. Artificial intelligence helps by automating tumor and organ outlining, improving planning speed and accuracy.
Overall, advancements in robotic surgery and radiation therapy have sharpened cancer treatment tools, making them more precise and safer. These developments have improved patient outcomes, shortened treatment times, and minimized side effects, benefiting clinicians and patients alike by increasing the number of lives saved and improved.
