Lung nodules are generally referred to as high density lesions detected by imaging, and the number of nodules is usually more than 3, and the size of the nodules is about 5-10mm. There are many reasons that lead to pulmonary nodules, such as tuberculosis, teratoma, lung cancer and so on.
1. Tuberculosis: due to tuberculosis foci caused by Mycobacterium tuberculosis infection, there are multiple diffuse small fibrotic and calcified tuberculosis foci, which will lead to the manifestation of many small nodules in lungs.
2. Teratoma: teratoma can be caused by abnormal differentiation of germ cells in embryonic stage, which leads to the phenomenon of many small lung nodules, which is relatively rare.
3. Lung cancer: due to the proliferation of cancer cells, which may lead to the manifestation of pulmonary nodules.
There are many other reasons that can lead to the phenomenon of many small lung nodules. It is recommended that patients go to regular hospitals, consult with professional doctors, cooperate with doctors to complete relevant examinations, clarify the causes, and deal with them positively.
