How long a 70-year-old man can live with lung nodules cannot be generalized, and it is related to the nature of nodules, staging and physical condition. 1. Benign nodules: if the patient is benign nodules, such as: fibroma, misshapen tumor, inflammatory pseudotumor, etc., its nodules are small, does not affect the patient’s respiratory function, generally do not need to be dealt with, and does not affect the patient’s life expectancy. If the nodules are large, surgical resection can be considered, and the general resection will not affect the patient’s life expectancy. 2. Malignant nodules: if the nodules are malignant, such as lung cancer, other malignant tumors metastasis, etc., the survival time of patients is often shorter, in addition, the survival time also needs to be combined with the pathological type of the tumor, staging, as well as whether the patients undergo surgical treatment or not, and whether the patients undergo radiotherapy after the surgery, and so on. 3. Physical condition, if the patient has more serious underlying diseases, the survival time may also be affected. Enhanced nutrition and appropriate activities are needed to increase resistance. It is important to note that when the elderly are found to have lung nodules, they should actively consult the doctor and choose the treatment according to the examination results, which will help to relieve the cause of the disease and prolong their lives.
