After the initial diagnosis of cancer , one of the immediate next step involves obtaining adequate tissue samples from the tumor through a biopsy to confirm the malignancy as well as to study the cell type and other characteristics . This step is very important as treatment protocols differ in different tumor subtypes and grades . Unfortunately majority of tumors are deep seated in the body and are usually adjacent to critical or vital organs or vascular structures . However interventional radiologists with image guidance such as CT or ultrasound are able to precisely access the tumors at almost all locations and safely carry out the biopsy with minimal complications . In Vydehi cancer centre we have a vast experience of performing every type of biopsy procedure however complex with maximal patient comfort and safety .
