What are the differences between renal pelvis cancer and kidney cancer?

The main differences between renal pelvic cancer and kidney cancer lie in their definitions, locations of onset, clinical manifestations, and treatment methods. 1. Different definitions: Renal pelvic cancer refers to a malignant tumor that occurs in the renal pelvis. Kidney cancer, on the other hand, refers to a malignant tumor originating from the epithelial cells of the urinary tubules in the renal parenchyma. 2. Different locations of onset: Renal pelvic cancer is a cancer that occurs on the mucosa of the renal pelvis, usually growing within the renal pelvis. Kidney cancer, on the other hand, is a primary renal cell carcinoma that usually appears inside the kidney. 3. Different clinical manifestations: Patients with renal pelvic cancer generally do not have obvious symptoms in the early stages. As the disease progresses, symptoms such as low back pain and hematuria may appear. The typical symptoms of kidney cancer patients are low back pain, abdominal masses, and unexplained hypertension. 4. Different treatment methods: For patients with renal pelvic cancer, if the disease is in its early stages, surgical treatment can be performed, such as partial nephrectomy or total nephrectomy. For kidney cancer patients, radical nephrectomy or other methods may be required. In addition, it is important to maintain good lifestyle habits in daily life, avoid smoking and excessive alcohol consumption to prevent aggravation of symptoms. At the same time, attention should be paid to a healthy diet, and foods rich in protein, such as eggs and milk, can be consumed appropriately to help enhance resistance. If significant discomfort occurs during this period, medical attention should be sought promptly to avoid delaying treatment.
