Patient Success Stories & Testimonials
- Dr. Balaji Subramanian is celebrated for his work with CyberKnife Radiosurgery. He has successfully treated patients with difficult-to-reach acoustic neuromas, preserving their hearing and facial nerve function. Additionally, his expertise in Hybrid VMAT for bilateral breast cancer has allowed numerous women to undergo radiation with minimal side effects to the skin and underlying organs.
- "I was diagnosed with a spinal tumour and was terrified of paralysis. Dr. Balaji Subramanian suggested CyberKnife treatment. The procedure was painless, and I was back home the same day. His precision and knowledge gave me a second life. He is truly the best radiation oncologist in Chennai."– S. Raghavan
- "Dr. Balaji treated my mother for cervical cancer. His approach is very detailed; he explained the entire IMRT process to us. The side effects were managed so well under his care. We are grateful for his kindness and expertise."– A. Joseph
- "I underwent radiation for prostate cancer with Dr. Balaji. He used a technique that spared my healthy organs, and I have had no major complications. His training from Germany really shows in his advanced approach."– K. Nair
Treatment Approach & Philosophy
- Dr. Balaji focuses on "Organ Sparing" strategies. His philosophy revolves around delivering maximum radiation dose to the tumour while rigorously protecting the surrounding healthy tissues (like the heart in breast cancer or rectum in prostate cancer). He believes in Preventive Oncology, educating patients on lifestyle changes to prevent recurrence.
- As a top CyberKnife specialist in India, Dr. Balaji leverages robotic radiosurgery and Hybrid VMAT to treat tumours with sub-millimetre accuracy. He constantly integrates findings from his research into clinical practice to improve dosimetric outcomes.
