Interventional oncology is a subspecialty field of interventional radiology that deals with the diagnosis and treatment of cancer and cancer-related problems using targeted minimally invasive procedures performed under image guidance. Interventional oncology has developed to a separate pillar of modern oncology and it employs X-ray, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to help guide miniaturized instruments (e.g. biopsy needles, ablation electrodes, intravascular catheters) to allow targeted and precise treatment of solid tumours located in various organs of the human body.
While the surgical resection of tumours is generally accepted to offer the best long-term solution, it is often not possible due the size, number or location of the tumour. Interventional Radiology therapies may be applied to shrink the tumour, making a surgical or interventional treatment possible.
Patients can greatly benefit from Interventional Oncology treatments. The minimally invasive nature of the treatments means they cause less pain, fewer side effects and shorter recovery times. Many of these procedures can be performed on an outpatient basis, thereby reducing costs.
