This is evidenced by the absence of invasion into surrounding tissue planes or metastatic spread to other structures. Although benign lung tumors do not pose a significant health problem, complications can result if an obstructive lesion predisposes the patient to develop pneumonia, atelectasis, or hemoptysis.
