Mediastinal tumors are rare lesions with an unknown cause for development. There is no screening test that can be routinely performed, and no preventative treatment to limit their likelihood.
Most tumors remain asymptomatic until they become large enough to compress surrounding structures in the chest cavity. Complaints of discomfort with breathing or swallowing or pain are common, though quite often the mass in the mediastinum will be discovered on a routine chest X-ray before any symptoms arise.
Once mediastinal tumors are discovered, the NYU Thoracic Oncology Program's expert staff can provide treatment.
