The specific survival time of 1cm lung nodule needs to be judged by a professional doctor in combination with the condition of the lesion. Benign foci can always survive and do not affect life expectancy; malignant foci, through surgical removal, the specific survival time can not be fully determined. 1. Benign nodules, such as fibrous foci or cysts, will not have any effect on life expectancy, and only require regular review without symptoms. Even if they cause clinical symptoms, they can be clinically cured after radical resection. 2. When malignant foci are found in the examination, the survival time is mainly judged by the 5-year survival rate, and the 5-year survival rate of early lung cancer can reach more than 90%, and part of the population can also survive all the time. If you find a 1cm nodule in the lung, you need to consult a doctor in time, and the professional doctor will decide whether to treat it with surgery immediately or continue to observe.
