Frequently Asked Questions
Dr. Bisht is a leading radiation oncologist whose main expertise lies in high-precision radiotherapy techniques, specifically Stereotactic Radiosurgery (SRS) for the brain and Stereotactic Body Radiation Therapy (SBRT) for cancers in the body, particularly lung, prostate, and breast cancer.
Cyberknife is an advanced, non-invasive robotic system that delivers high doses of radiation with extreme accuracy. Its key benefits include its ability to treat tumours anywhere in the body, track tumour motion in real-time (e.g., in the lungs), deliver treatment in fewer sessions (1-5), and minimise side effects by sparing healthy tissue. Dr. Bisht is a highly trained expert on this platform.
Yes, SBRT is an excellent non-invasive treatment for localised prostate cancer, often considered an alternative to surgery. It delivers highly focused radiation in just five sessions and has shown success rates comparable to longer radiation courses and surgery, with a favourable side effect profile. Dr. Bisht is one of the top specialists for prostate SBRT in India.
Conventional radiation is delivered in smaller doses over many weeks (25-35 sessions). SBRT uses highly advanced technology to deliver a much larger, ablative dose of radiation in very few sessions (typically 1-5). This precision allows for higher tumour control while minimising exposure to nearby healthy organs.
Dr. Bisht is the recipient of several prestigious awards, including the AROI Overseas Fellowship and the European Society of Radiation Oncology (ESTRO)-Varian Award, which highlights his international recognition and contribution to the field of oncology.
Absolutely. SBRT is a standard of care for early-stage, inoperable non-small cell lung cancer and is also used to treat limited metastases to the lung. Its ability to account for breathing motion makes it highly effective and safe.
Dr. Shyam Bisht has an extensive and rich experience of over 17 years in the field of radiation oncology.
