Lung nodules that grow 5 millimeters in a year are fast-growing and need to be seen by a doctor in a timely manner to determine the cause of the nodule’s growth and then treat it in a timely manner.
Lung nodules are categorized into benign nodules and malignant nodules. Benign nodules, especially smaller solid nodules, have less impact on the human body, and regular checkups to observe the changes of the nodules are sufficient. However, malignant nodules need to be treated in time, including precancerous lesions, lung carcinoma in situ, early lung cancer, etc. Timely detection and early treatment can significantly improve the survival period and improve the prognosis.
Generally, the size of benign nodules basically does not change. On the other hand, malignant nodules tend to grow gradually, with changes in size, density and morphology, etc. Therefore, when a lung nodule is found to grow 5 millimeters in a year, it needs to cause importance and seek timely medical treatment.
