Hemoptysis, Cough, and Weight Loss

A 71-year-old male presents to his primary care physician with an 8-week history of cough with intermittent blood-tinged sputum. He denies fevers or sick contacts. However, he notes a 20-pound weight loss in the last 3 months and feeling more fatigued. He has a 40-pack-year smoking history. He previously worked as a welder in a shipyard for 30 years before retiring 5 years ago. His past medical history only includes hypertension. Breath sounds are equal without crackles. Cardiac exam also reveals a regular rate and rhythm. His blood pressure is 120/80 mmHg, and heart rate is 88/min. An initial chest x-ray reveals a mass in the right hilar region measuring 3.1 cm × 3.5 cm.
