Whether a lung nodule can grow to 2cm in a year is related to the nature of the nodule. Some malignant lung nodules can grow to 2cm in a year.
Most of the nodules that can grow to 2cm in a year are malignant, and benign lesions do not grow as fast.
Benign nodules usually grow slowly, and benign nodules in the lungs are rarely tumors, and even benign tumors don’t grow very fast, usually by a few millimeters, and basically don’t grow to 2 cm in a year. Inflammatory lung nodules may gradually shrink or even disappear.
If the lung nodule is malignant, the growth rate will be faster, it is possible to grow to 2cm in a year, because malignant tumors belong to abnormal proliferation, the tumor cells divide infinitely, which leads to the nodule grows very fast, and metastasis may occur at the same time of rapid growth.
Therefore, if the lung nodule grows to 2cm within one year, it should be highly considered as a malignant tumor, and should be subjected to bronchoscopy or lung puncture biopsy as early as possible to determine the nature of the nodule through examination, and choose the appropriate treatment without delay.
