What are the symptoms of advanced kidney cancer?

The symptoms of advanced renal cancer are diverse and severe, mainly including: 1. **Urinary system symptoms**: The classic triad includes hematuria, flank pain, and an abdominal mass. Hematuria is often painless and intermittent; flank pain results from tumor compression of surrounding tissues; and the abdominal mass becomes apparent as the tumor grows larger. 2. **Metastatic symptoms**: Advanced kidney cancer may metastasize to the lungs, bones, liver, and other areas, causing symptoms such as cough, sputum production, chest pain, bone pain, pathological fractures, and jaundice. 3. **Associated symptoms**: These include hypertension, anemia, hyperglycemia, and abnormal liver function, which can significantly impair the patient's quality of life. The presence and severity of these symptoms are closely related to the tumor's location, size, and extent of metastasis. If the above symptoms occur, prompt medical consultation and professional treatment are recommended.
