Be aware, however, that if surgery is being considered for lung cancer, it is a good sign, signifying that the degree of tumor involvement or spread is probably limited.

He or she should conduct a pulmonary function test before surgery; this test helps identify patients with extremely high surgical risk. Also, cardiopulmonary exercise testing may be helpful to determine whether or not you can withstand the rigors of this surgery.
