Generally speaking, 2 to 3 years are the most dangerous period after kidney cancer surgery. After kidney cancer surgery, about 2 to 3 years is the recovery period, which is the most risky period for patients, if they don’t pay attention to care, their condition may recur at any time, and after recurrence, the cancer cells may be transferred to lymph nodes of the whole body or blood. Generally speaking, if the cancer has not recurred after 5 years after kidney cancer surgery, it means that the condition is basically stable and the cancer cells are not easy to spread or metastasize. For the majority of kidney cancer patients, the survival rate is relatively high within 5 years after surgery, and some patients may survive for about 10 years or even longer. If kidney cancer patients have already undergone surgery, they should have regular follow-up to know whether there is any tendency of recurrence or metastasis of the disease. Early diagnosis and early treatment can better prevent the metastasis of cancer cells.
