Lung masses over 3cm are considered malignant until proven otherwise. Your subsolid nodule may or may not be malignant. I would ask the radiologist& a pulmonologist if a Pet Scan or a lung needle biopsy would be the next advisable test.

There are many factors to consider. The scans may be reviewed during a virtual consult with Healthtap. The size, growth, location, calcification are among these factors. In addition, your risk factors include smoking, family history of lung cancer. Biomarkers may support the diagnosis but most often biopsy is indicated for higher risk lesions.
