What is a noncalcified nodule?

Hello, Anon. Thank you for writing today.

Calcified nodules contain deposits of calcium which are visible on imaging scans. This can happen when the body responds to infections such as tuberculosis and usually means a nodule is not cancer. Non-calcified nodules are classified as ground glass opacities, partially solid or solid nodules. This may be the result of inflammation caused by infection or other lung damage, but could also be a sign of a type of lung cancer that is slow-growing.

Most small non-calcified nodules are followed through a yearly follow up
screening. Depending on the size, your doctor may recommend follow
up imaging tests earlier than a year.  If the nodule grows, further testing may be needed to determine if it's cancerous.
