Many of you have written to me after receiving the news that you have a lung mass. How scary. And how totally confusing.
First it helps to define what a lung mass is. A lung mass is a "spot" on the lungs seen with an x-ray or CT scan that measures at least 3 cm (1 ½ inches) or more in diameter. If a spot or spots are less than 3 cm they are considered lung nodules.
What are the possible causes of lung nodules and masses? And what can you expect in the upcoming days if you've heard that news?
