Dr. Sumit Sharma is an experienced Interventional Radiologist and Onco-Imaging Specialist in Kolkata with more than 13 years of overall clinical experience. He currently serves as Head of the Department of Interventional Radiology at HCG Cancer Center, New Town, Kolkata.
He completed his MBBS from Krishna Institute of Medical Sciences, Hyderabad, followed by MD in Radiology from Bharath Institute of Higher Education and Research, Chennai. He later pursued a specialised Fellowship in Onco-Imaging and Interventional Oncology from Tata Medical Center, Kolkata.
Dr. Sumit Sharma specialises in minimally invasive image-guided procedures that use ultrasound, CT and fluoroscopy to diagnose and treat complex conditions without conventional open surgery.
His clinical expertise includes interventional oncology procedures such as tumor ablation, embolization, image-guided biopsy and minimally invasive treatments for selected cancers.
He is also experienced in vascular and non-vascular interventions, including drainage procedures, venous access procedures, biliary interventions and image-guided therapeutic procedures.
Dr. Sharma follows a precision-based approach using advanced imaging guidance to target abnormal tissue while minimising damage to surrounding healthy structures and supporting faster recovery wherever clinically appropriate.
Interventional radiology uses imaging guidance such as CT, ultrasound and fluoroscopy to perform minimally invasive diagnostic and therapeutic procedures through small punctures rather than open surgery.
Image-guided biopsy uses CT or ultrasound to accurately obtain tissue samples from suspicious lesions for laboratory diagnosis.
Radiofrequency ablation uses heat generated through a needle electrode to destroy selected tumors or abnormal tissue under imaging guidance.
Microwave ablation uses electromagnetic energy to heat and destroy selected tumors and may be used for certain liver, lung and other lesions.
Tumor ablation involves targeted destruction of cancerous tissue using thermal or other energy-based techniques under precise imaging guidance.
Transarterial chemoembolization delivers chemotherapy directly into the blood vessels supplying a tumor and then blocks those vessels to concentrate treatment locally.
Radioembolization delivers radioactive microspheres through the arteries supplying selected liver tumors to provide targeted internal radiation therapy.
Embolization blocks selected abnormal blood vessels to control bleeding, reduce tumor blood supply or treat vascular abnormalities.
A fistulagram is an imaging procedure used to evaluate blood flow through an arteriovenous fistula or graft and identify narrowing or blockage.
CT-guided procedures use real-time or sequential CT imaging to accurately position needles or instruments for biopsy, drainage or treatment.
Ultrasound guidance allows accurate placement of needles, catheters or treatment devices while visualising internal structures in real time.
Image-guided drainage procedures are used to remove infected fluid, abscesses or abnormal collections through minimally invasive catheter placement.
Biliary interventions may include drainage or stent placement to relieve bile duct obstruction caused by cancer, stones or other conditions.
Image-guided venous access procedures help safely place long-term catheters or ports for chemotherapy, medications or other treatments.
Minimally invasive cancer treatment uses imaging-guided procedures such as ablation and embolization to treat selected tumors without conventional open surgery.
