A 42-yeаr-оld femаle is nоted tо hаve a solitary pulmonary nodule in the right upper lobe on a routine plain chest film. This was not evident on a chest film taken one year earlier. The patient has a history of invasive ductal carcinoma of the right breast; she underwent a mastectomy 6 years ago. At that time, no lymph nodes were involved. She has remained disease free for the past 6 years until the plain chest film confirmed the pulmonary nodule. She has no known risk factors for pulmonary tuberculosis. The patient smokes 5 cigarettes/day. She denies hemoptysis or other pulmonic or constitutional symptoms and denies recent domestic or foreign travel. On physical exam, her temperature is 98.2°F. She has no lymphadenopathy or abnormal palpable breast masses on the left side. Her CBC is normal. A Chest CT scan revealed only a nodular opacity in the right upper lobe measuring 2 cm x 1.5 cm. Which of the following interventions is the most appropriate next step in the diagnostic evaluation of this patient?
