MRI : AnMRIis more accurate compare to a CT scan . It is more effective and can examine the region between the lung .
Bronchoscopy : This turn back the airway of the lungs .

The survival of the fittest rate after treating pancoast tumor with chemotherapy , surgical operation , and radiation sickness during 2 years is 55 - 70 % . The 5 years natural selection charge per unit is the range of 55 - 74 % . T3 and T4 have the better chance of survival .
