Lung nodules growing fast may be inflammatory nodules or malignant nodules.
1. Inflammatory nodule: if the lung nodule grows fast within one month, the doubling time is less than 15 days, it is more likely to be inflammatory nodule, which can be caused by Candida, Aspergillus and other infections, and it is a benign nodule, and it can be treated with fluconazole and other medicines under the guidance of the doctor, and the prognosis is generally good.
2. Malignant nodule: if the lung nodule grows faster in half a year or one year, which is in line with the growth pattern of the tumor, then it is more likely to be malignant nodule, which can be lung cancer, metastatic tumor, etc. It should be treated with chemotherapy drugs such as erlotinib under the guidance of doctor or surgical resection, etc. to improve the prognosis.
