Where in the chest is the media steinum?!
Question: Lung cancer mets
Answers:
The area between the lungs. The organs in this area include the heart and its large veins and arteries, the trachea, the esophagus, the bronchi, and lymph nodes.
Performing a chest X-ray is the first step if a patient reports symptoms that may be suggestive of lung cancer. This may reveal an obvious mass, widening of the mediastinum (suggestive of spread to lymph nodes there). http://en.wikipedia.org/wiki/Lung_cancer
Stage III The cancer has spread to the lymph nodes in the mediastinum (middle area between the lungs that contains the heart, major blood vessels and other structures). http://www.antigenics.com/diseases/lungcancer.html

The mediastimum is the mid-portion of the chest that surrounds the esophagus, and the area that surrounds the heart (it is outside the pericardium. It is a common place for metastatic disease from lung CA as it houses alot of nodal tissue.
The location is mid-line. Hope this helps - best wishes.
Simply, the mediastinum is the cavity towards the midsection of the chest. It starts right inside the chestbone and goes to the front of the spinal cord. It is basically the entire chest cavity minus the lungs.
The mediastinum is a common site of cancer because there is a number of types of tissue that supply the chest and lower portions of the body with blood, neural signals, and lymphatic tissue. Each of these types of tissue can become cancerous, so neurogenic (nerve origin), lymphatic, or vascular cells can lead to cancer. This is not necessarily true of other regions of the body.
