How many years can you live after resection of renal malignant tumor depends on the course of the tumor, the degree of malignancy and the effect of treatment, if the course of the disease belongs to the early-middle stage, the degree of malignancy is low and the effect of the treatment is good, you can generally survive for more than 5 years, if it belongs to the advanced stage of the disease and the degree of malignancy is high, you can generally only live for less than 5 years, which is explained as follows. For early stage renal malignant tumor patients, most of them can survive for a long time through radical surgical resection. If belongs to middle stage renal malignant tumor patients, after radical surgery, actively cooperate with other treatments, regular review, control the condition and prevent recurrence, the 5-year survival rate is also high. If patients with advanced renal malignant tumors have high degree of malignancy, poor pathological typing, and high chance of recurrence after surgery, the treatment effect is relatively poor at this time, and they may only live for 1-2 years. Therefore, after renal malignant tumor resection, patients should actively cooperate with doctor’s treatment, regular life, light diet, improve body immunity, regular review, to prolong the survival period.
