A 60 year old male was diagnosed as carcinoma right lung. CECT of the chest shows a tumor of 5x5 cm in upper lobe and another 2x2 cm size tumor nodule in middle lobe. Which of the following is the treatment of choice?

Question does not indicate the type of lung cancer in the patient. Depending on the given size of the cancer (5cm) and absence of nodal involvement or metastasis, patient is in T2 N0 M0 or Stage I cancer. The current standard of treatment of stage I and II lung cancer is surgical resection, accomplished by lobectomy or pneumonectomy, depending on the tumor location.
