It is possible to cure a kidney tumor in its early stage, and if it is cured, it can survive for a long time. Most of the early stages of kidney tumors can be cured by complete removal of the tumor through surgery. However, even in the early stage of kidney tumor, there may be tiny metastases to other parts of the body through blood or lymphatic transfer, and recurrence and metastasis may occur after surgery, so regular review is needed after surgery to detect recurrence and metastases in time and to deal with them in time. Even if metastasis is found, especially isolated metastasis, it may be cured again through active surgical resection, and it is possible to achieve long-term survival.
