According to the Cleveland Clinic, mediastinal tumors are rare, occurring in less than 1% of the population. The term **what is a mass in the middle of the chest** refers to growths that develop in the mediastinum, the central area of the chest that separates the lungs. These masses can be benign (non-cancerous) or malignant (cancerous) and may be discovered incidentally during imaging for another condition.
