Inflammation is likely to cause nodules to occur. Nodules caused by inflammation are mainly due to long-term stimulation by pathogenic bacteria, causing tissue proliferation to form nodules, or tissue fibrosis and calcification to form nodules. For example, tuberculosis caused by Mycobacterium tuberculosis attacking the lungs, some patients show nodular lesions in the lungs. Nodules caused by inflammation can be controlled with antibiotics, which will help the nodules to subside. For example: tuberculosis nodular lesions in the lungs, you can follow the doctor’s instructions through the anti-tuberculosis treatment drugs to make the lesions disappear, such as isoniazid, rifampicin, levofloxacin and so on. For patients who have no clinical symptoms after the basic control of inflammation after treatment, but the inflammatory nodules have not completely subsided, we should consider that the nodules are due to malignant tumors, it is recommended to consult the hospital in a timely manner, and if necessary, need to do a puncture pathology examination of the nodules to clarify the cause of the disease.
