The best way is to accumulate practical experience and grow quickly by performing surgeries in the operating room.
Mediastinal tumors are classified into the upper, middle, and lower mediastinum.
This tumor is located in the upper mediastinum.
It is very likely caused by the metastasis and spread of lung cancer. Typically, cancer cells spread most commonly through lymphatic spread, blood spread, and infiltration into adjacent organs.
Blood spread is not as terrifying as imagined; not all blood spread will necessarily lead to systemic spread.
A cancer cell entering the bloodstream already needs to overcome multiple barriers in the body.
Even if it enters the blood, it may be expelled from the body through the glomerulus or sweat glands. It may also be detected and killed by the body's immune cells.
Even if it spreads through the bloodstream and ultimately metastasizes to other organs, it would still need to withstand multiple immune mechanisms of the body to take root.
