20 NCCN Guidelines for Patients ® : Lung Cancer – Non-Small Cell, 2018 2 Assessing lung nodules Review Review It takes a team of experts to assess lung nodules for cancer. Tobacco smoking is the biggest risk factor for lung cancer. Signs of cancer can be found with imaging tests. For lung cancer, doctors assess a nodule’s features, the condition of the lung tissue, and for PET hot spots. Doctors assess changes in a nodule’s size and density with repeat testing. Nodules that increase fast in size or density are more likely to be cancer. Testing of tissue that is removed by biopsy or surgery is needed for diagnosis.
