Division of Thoracic Surgery

Our expert thoracic surgeons employ the latest and most effective surgical techniques in treating chest diseases, such as:
City of Hope’s minimally invasive techniques play a major role in diagnosis and treatment of thoracic cancers, ranging from lung biopsy to lung resection to esophageal removal and reconstruction, using the robotic da Vinci Surgical System. Minimally invasive approaches are used whenever possible and may result in quicker recovery times and fewer surgical complications.
Patients benefit from an integrated approach to managing conditions affecting the lungs and thoracic cavity: a coordinated effort between all members of the treatment team determines the need for postsurgery follow-up with radiation and/or chemotherapy to ensure the best possible outcomes.

The extensive experience and unique training of our thoracic surgeons also mean they can handle more complex cases that may be deemed inoperable elsewhere.
