Navigating the guides

The following set of guides (5–6) will list

your next screening test based on the type

of lung nodule found on the first (baseline)

LDCT test.

Next steps if solid or part-solid lung nodule

Guide 5

lists when you should get your next

screening test based on the results of the first LDCT

test for a solid or part-solid lung nodule. The time of

the next test depends on the size and density of any

lung nodules found. If you have smaller nodules, no

additional testing is needed before your next LDCT

test 1 year from now. Slightly larger nodules should

have a follow-up LDCT in 3 or 6 months. For the

largest nodules, with the highest risk of cancer, you

may have an additional test such as a PET/CT scan.
