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

Guide 10

lists when you should get your follow-up

test for a part-solid lung nodule seen on chest CT or

PET/CT. You will have further testing based on the

nodule size and concern for cancer. If there is a low

concern for cancer, you should get an LDCT in 3 or

6 months. If there is a high concern for cancer, you

should have a biopsy or surgery. This is done instead

of waiting to see if anything changes over time. A

biopsy or surgery of the nodule can confirm if cancer

is present.
