How long does it take for renal pelvis cancer to go from early to advanced stage cannot be determined clearly, there is no relevant research stating the time, and it needs to be judged according to various reasons such as patient’s individual physique, treatment measures, and severity of the disease. Renal pelvis cancer is a kind of tumor that occurs in the epithelium of renal pelvis or renal calyx. In the early stage, painless hematuria may occur, and as the tumor increases in size, hydronephrosis, abdominal distension, renal colic and other symptoms may occur. In early stage, renal pelvis cancer can be treated by surgical resection and prevented from recurrence with chemotherapy after surgery, while in late stage, only chemotherapy can be used to control the continuous spread of cancer cells, relieve symptoms and prolong survival. It is recommended to go to regular hospitals for comprehensive assessment, and follow the doctor’s instructions to cooperate with the treatment and actively standardize the treatment, which can help to improve the quality of life of patients and prolong their survival period.
