Dr. Sundar Suwal

Dr. Sundar Suwal is a Consultant Radiologist at Kathmandu Cancer Center, working in interventional radiology. At KCC he is the interventional radiologist for brachytherapy and brachy-ablation, with experience in minimally invasive, image-guided procedures in inner organs such as the lungs, liver and lymph nodes.

He has worked in the Department of Radiology and Imaging at Tribhuvan University Teaching Hospital (TUTH), Kathmandu. In 2023 he published a case report in the Journal of Contemporary Brachytherapy on interstitial brachytherapy under ultrasound and CT guidance for a recurrent internal mammary lymph node in breast cancer.

He is a co-author of KCC's 2025 study on CT-guided HDR interstitial brachytherapy for lung lesions, published in Brachytherapy, the journal of the American Brachytherapy Society. The paper won Best Paper at IBSCON 2025.

Brachyablation of lung tumours needs interventional radiology skill, a dedicated radiation oncology team and real-time CT guidance. Dr. Suwal places the thin catheter into the tumour under CT guidance, and the radiation plan is delivered with KCC's radiation oncology team.

The same image-guided approach is used for needle biopsy, so patients with a suspected cancer can be diagnosed, and if suitable treated, within one cancer centre.
