Bio

Dr. Rishab Kumar, a Radiation Oncologist with 8 years of experience in this technology and patient-driven field completed his Senior Residency at AIIMS, New Delhi, ILBS and SGPGI. He completed his Junior Residency in Radiation Oncology at Vydehi Institute of Medical Sciences and was awarded MD by Rajiv Gandhi University of Health Sciences, Bangalore in 2017. During this period he learned about the nuances of Stereotactic Radiotherapy and radiosurgery and advanced image-guided Radiotherapy. Dr. Rishab performed the world’s first Robotic Liver HDR Brachytherapy and published Indian data on the role of HPV and telomerase in cervical and head and neck cancers respectively. He is specialized in using advanced forms of radiation to treat cancers of the Brain, Head, Neck, Breast, Gastrointestinal and Gynaecological regions. Cancer is best treated in a multi-disciplinary setting. All of his patients benefit from the combined knowledge of multiple specialists who are dedicated to curing their cancer and resuming their lives. Dr. Rishab have received advanced training to deliver high-precision personalized radiation to kill cancer and cause the least amount of side effects.
