Hello, depending on the size of the tumor involved and weather the tumor has spread to the lymph node or the chest in x-rays there is a wide margin of recovery and life expectancy. I have found literature stating any where from 5 month for larger tumors that involve lymph nodes to 18 month or more for smaller tumors. It really all depends on the type of tumor involved and how far along the tumor has progressed. I am sending you a few links to some information on the procedure and possible life expectancies. I hope this helps some but if there is anything else that you need be sure to let me know.
