Stage I kidney cancer generally belongs to early-stage kidney cancer, which usually presents no symptoms and is most often discovered during physical examinations. This is the case for more than 50%-60% of kidney cancers. The examination for kidney cancer also requires a CT scan of the kidney and an enhanced CT scan to confirm the diagnosis. If it is stage I, the cure rate through surgical removal is very high. Surgical operation is the first choice for treating kidney cancer and is recognized as a means to cure kidney cancer. Early-stage kidney cancer can be treated with laparoscopic or traditional open surgery, which involves a radical removal of the kidney. For patients with stage I kidney cancer, the five-year survival rate can reach about 92%. Post-surgery, regular follow-up visits are necessary to check for recurrence, metastasis, and new tumors. After surgery, stage I kidney cancer patients should have follow-up visits every three to six months for the first three years and annually thereafter. Stage I kidney cancer has a chance of being completely cured but also the possibility of recurrence, so regular follow-ups are essential.
