Many medical conditions can cause spots to form on lungs.
The most common in the US include prior tuberculosis infection and/or prior histoplasmosis infection (a fungal infection). These spots may be called "nodules" by your doctor. If they are small (less than 8 mm) they may be followed over time with repeat/serial scans of the chest. If in 2 years they do not change they are benign.

In brief: Infection
Most common finding on chest radiograph is from infection.
Nodules related to granulomas from infections like TB or in southwest coccidiodomycosis (valley fever). Scars relatrd to previous infections not uncommon.

In brief: "Spots?"
For a non calcified lung nodule, 50% risk of malignancy.
Non neoplastic lesions are the pneumoconioses and grannulomatous lung disease, tuberculosis.
