In daily life, people may hear that the cure rate of early stage kidney cancer is almost 100%. Although the cure rate of early stage kidney cancer is really high, this statement is not accurate. Even if early stage kidney cancer patients actively undergo radical surgery, the cancer cells may still recur and metastasize in the body, so it is impossible to be 100% cured. Clinical data shows that the 5-year survival rate of early kidney cancer patients can be more than 90% after active treatment, especially for mild early kidney cancer less than 4cm, the 5-year survival rate can be more than 95% or even close to 100%. The reason why the 5-year survival rate of early stage kidney cancer is so high is generally believed to be due to the fact that kidney cancer is in the early stage, the cancer is small in size, the invasion of surrounding tissues is shallow, and it has not yet brought serious adverse effects to the body, and the chance of metastasis is also small, so the chance of recurrence after surgical resection is low and the 5-year survival rate is high. However, even if the prognosis of early kidney cancer is better after surgery, patients should not let down their vigilance and need to follow medical advice for regular review. 2 years after surgery is the peak of recurrence, and some patients are prone to recurrence 5-10 years after surgery, so patients should have regular review after surgery for early detection of recurrence and early treatment. The doctor will judge whether to administer radiotherapy according to the actual situation of the patient. Pay more attention to avoid factors that may induce or aggravate kidney cancer, such as smoking, drinking, obesity, etc.
