Whether a 70-year-old man needs immediate surgery for kidney tumor needs to be judged in combination with the tumor status and the patient’s own physical condition. If the tumor itself is benign or the patient’s physical tolerance is poor, immediate surgery is not needed; if the malignant tumor is in early stage and the patient’s physical condition is good, immediate surgery is possible. 1. If the tumor is benign in nature and there is no obvious physical symptom, the patient can be observed regularly and there is no need to rush for surgery; if the tumor is found to be intolerable, the patient’s physical condition can be adjusted and recovered to relatively normal, and then the patient can be operated at a later stage. 2. If the patient is in early stage of malignant tumor and his physical condition is good, he needs to have surgery immediately to prevent the disease from progressing and affecting the postoperative recovery. The 70-year-old man found kidney tumor, need to go to the hospital in a timely manner, after diagnosing the specific condition, under the guidance of the clinician for standardized treatment, to avoid causing delays in the condition.
