Doctor: I don’t know what the size of the tumor was at that time. At present, you should check the liver function, kidney function, blood and urine routine to see the general condition first. After surgery, there is only one kidney left, so the medication and diet must pay attention to protect the kidney function. Chest X-ray, abdominal ultrasound and CT examination should be conducted regularly so that metastasis can be detected and treated as early as possible. Kidney cancer is not sensitive to radiotherapy and chemotherapy, so no matter it is in early or advanced stage, radiotherapy and chemotherapy are not needed. Instead, interferon is used as postoperative adjuvant therapy, so it is recommended to use interferon for at least 3 months after checking, but interferon has certain side effects, so during the period of using interferon, it is recommended to check liver and kidney function and blood routine at least every week. Ganoderma lucidum powder has no national drug approval number, its mechanism of action and effect is not clear.
