NCCN Guidelines for Patients
Lung Cancer Screening, Version 1.2017
Next steps if new lung nodule on follow-up
describes the suggested course of
care if your doctors think there’s an infection or
inflammation. During the screening process, a new
nodule or more than one new nodule may appear.
The nodule should be re-checked with LDCT in 1 to 3
months. During this time, your doctors may treat the
infection or inflammation.
If the nodule is smaller or gone, it is not likely to
be cancer. Screening with LDCT will be in 3 to 6
months for a nodule (or more than one nodule)
that is getting better. You should get an LDCT in a
year if the nodules are gone and they improved on
this LDCT. If the new nodule is not an infection or
inflammation, the doctor will follow the other guides
when scheduling the next screening test.
Many people have nodules in their lung.
Nodules can be caused by cancer, infections,
scar tissue, or other conditions.
Often, screening tests are repeated over time to
assess if a nodule may be cancer.
The schedule and type of screening test
depend on whether there are changes in a
nodule’s size, density, or both.
What happens after the first test? Follow-up or yearly screening LDCT
