If kidney cancer is detected early, it can be cured through surgery. Unlike some malignant tumors, kidney cancer has good treatment outcomes. If the cancer is less than four centimeters in diameter, the five-year survival rate after surgery can exceed 90%. If it is less than seven centimeters, the five-year survival rate after surgery can also reach 80%. Even if the cancer has metastasized to distant sites, removing the kidney can still help the patient's survival. Therefore, the earlier the tumor is detected, the better the treatment outcomes. Kidney cancer surgery is generally done through laparoscopy or open surgery. Postoperative diet should be high in protein, fiber, and nutrients, as the healing of the kidney cancer incision also requires a solid nutritional foundation. It is necessary to eat less spicy and stimulating food, and to maintain a low-salt, low-fat diet. The most important thing for kidney cancer is to have regular follow-ups to understand the recovery situation and check for any recurrence or metastasis of the tumor.
