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. Drink lots of water (at least 2 litres every day) - not soda or juices - because it helps your skin stay elastic.

The mediastinum is bordered by the breastbone (sternum) in front, the spine in back, and the lungs on either side. What is a Mediastinal Tumor? The mediastinum lies between the right and left pleurae (a delicate membrane that encloses the lungs) in and near the median sagittal plane of the chest. It extends from the sternum in front to the vertebral column behind, and contains the heart, aorta (the body's largest artery), esophagus, thymus (one of the glands), trachea, lymph nodes, and nerves.
