We evaluate and treat a high volume and wide variety of mediastinal diseases. Since many of these lesions are benign, minimally invasive mediastinal-masses-and-tumoursapproaches, which allow for less discomfort and faster recovery, can often be utilized. For example, in the past year alone, Fortis thoracic surgeons have removed or biopsied  or operated 177 mediastinal masses – a very large volume of these cases for a single institution. Many of the mediastinaltumours and thymomas (less than 6 cm) can be removed by minimally invasive surgery(VATS or Robotic Surgery)
