It's too late for me but stretch marks are perfectly preventable (sometimes, though, whatever you do you still get them) so here are some tips I give to my friends: Maintain a healthy skin.

Mediastinal tumors are growths that form in the mediastinum. This is an area in the middle of the chest that separates the lungs. The mediastinum is the part of the chest that lies between the sternum and the spinal column, and between the lungs. This area contains the heart, large blood vessels, windpipe (trachea), thymus gland, esophagus, and connective tissues. Mediastinal tumors are rare.
