Cancerous nodules, on the other hand, can double in size on average every four months (some as quickly as 25 days, some as slowly as 15 months).

Growth can be evaluated through a series of x-rays or CT (computed tomography) scans over a period of time..

Can a CT scan tell if a lung nodule is cancerous?

What causes multiple nodules in the lungs?

The aetiology of multiple pulmonary nodules is quite complex, with metastatic disease being the most common cause. Other possibilities include sarcoidosis or an inflammatory process, such as fungus, tuberculosis, nocardiosis or septic emboli.

What kind of infections cause lung nodules?

Infections: Infectious causes of nodules may include bacterial infections such as tuberculosis and other mycobacterial infections, fungal infections such as histoplasmosis, blastomycosis, aspergillosis, and coccidiomycosis, and parasitic infections such as ascariasis (roundworms), echinococcus (hydatid cysts), and …
