Lung Cancer Screening, Version 1.2017

What happens after the first test? Follow-up or yearly screening LDCT

Next steps if non-solid lung nodule on

follow-up

Guide 11

lists the recommended care based on

the results of the follow-up or yearly LDCT test for

a non-solid lung nodule. If the non-solid nodule

has disappeared or gotten smaller, there is a good

chance that it was a small infection that resolved and

was not cancer. For a new or stable but small non-

solid nodule, your next LDCT should be in 1 year.

If stable and 20 mm or larger or growing, your next

LDCT should be in 6 months.

If a nodule has grown or become more solid, it may

be cancer. Because of this concern, a biopsy or

surgery is recommended.

For multiple non-solid nodules, doctors will measure

the largest nodule. They can use the guides (like

those in this chapter) to manage the nodules. If

the doctor thinks the nodules are an infection or

inflammation, your next LDCT will be in 1 to 3

months. If the nodules grow quickly, the doctor

should check for inflammation or another cancer.
