Since these risk factors are numerous and have different effects on the malignancy risk, it is proposed to assess final risk categories concerning the probability of malignancy  Table. Now, it is aimed for to separate high-risk lesions from low-risk ones by considering more parameters than subject characteristics alone See Table. In another article we presented some features that can help to differentiate between benign and malignant lesions click here Unfortunately, there is considerable overlap and often no definitive answer can be given based on imaging morphology.

If unchanged and solid component below 6mm, CT annualy for 5 years. CT in 6 to 12 months to confirm persitance, then CT every 2 years until 5 years.
Heber MacMahon’s publications, visit PubMed. Spleen Size – Peds. Subsolid nodules in the adenocarcinomatous spectrum were formerly known as bronchoalveolar carcinoma or BAC. Defining flleischner or low-risk is currently more difficult than it was in the old guideline. If unchanged, consider CT in 2 and 4 years. A new pathology-based classification for adenocarcinoma was introduced in and this current classification makes distinction fleishner CT in 3 to 6 months, then consider CT in 18 to 24 months.

Do not use for lung cancer screening or in patients with known primary cancer or immunosuppression.
