What is Mediastinal Cancer

Tumors that form in the mediastinum are also known as primary tumors. The central portion of the chest cavity located behind the sternum (breast bone) and between the lungs and extending from the neck above to the diaphragm below is known as the mediastinum. The mediastinum contains the heart, thoracic aorta, trachea (airway), esophagus (swallowing passage), thymus gland, and lymph nodes.Sometimes mediastinal tumors will develop because cancer from another part of the body has spread and are known as a secondary tumor.
