I had a friend that died a couple of years ago and he had thymus cancer. It is a really rare cancer and the tumors start from thymic epithelial cells. I was an oncology nurse for 3 ½ years and I had never had a patient with this type of cancer. In fact, these tumors occur at a rate of only 1.5 cases for every million people each year in the US.

The thymus is a part of the chest known as the mediastinum, the space in the chest between the lungs that also contains the heart, part of the aorta, the esophagus, part of the trachea and many lymph nodes.

The optic nerve is the main nerve to the eye (located in the back of the eye) that is responsible for transmitting electrical impulses to the brain.  Damage usually occurs as a result of elevated pressure of the fluid (aqueous humor) in the eye.
