Welcome to Mayo Connect @pazart. Depending on the doctors involved in the case,
-they may want a PET scan to determine if the mass is isolated to the lung,
-they may want a biopsy to determine the cellular makeup of the mass,
-they may want to surgically remove the mass,
-or they may come up with some other creative first steps.
The size and spiculated nature are indicating that some action is needed. That being said, if you or the patient are stable and not in an emergency/inpatient situation, you have time to take a slight pause and assess what steps make the most sense. Every patient is different considering overall health, preexisting conditions, age, tolerance for treatments, etc.
These situations are stressful and overwhelming. Are you the patient? Do you have upcoming appointments scheduled, and with which type of doctors?
