Lung cancer with multiple nodules in both lungs may be intrapulmonary metastasis, primary lung cancer, or non-malignant tumor nodules caused by infection and other factors.
Lung cancer is prone to intrapulmonary metastasis, and the metastatic tumors may be nodular, usually occurring at the outer edge of both lungs first, usually evenly distributed, which mostly indicates that the disease has reached the middle or advanced stage; meanwhile, many primary lung cancers also show multiple nodules from the very beginning.
Many benign lesions of lungs are also manifested as lung nodules, such as bacterial, viral, mycoplasma and other infections in the lungs can form the manifestation of multiple tiny nodules in the lungs; the most typical one is tuberculosis, especially after chemotherapy, the immunity is reduced, and the latent bacteria in the body are prone to recurrence.
CT imaging performance: lung cancer nodules are generally irregular in shape, with unclear boundary and burrs at the edge, uneven enhancement and fast growing foci on enhanced scan; non-malignant tumor nodules are usually regular in shape, with clear edge and slow growing foci.
Lung cancer or multiple nodules in both lungs should be examined in time, and the physician should make clinical judgment and adopt appropriate treatment plan.
