Stage III renal cancer mainly refers to the primary lesion invading the perirenal tissues, not passing through the perirenal fascia, or or the tumor forming cancer embolus in renal vein and inferior vena cava, or regional lymph node metastasis, and the typical clinical symptoms include hematuria, pain, and masses. 1. Hematuria: the tumor invades the ureter and causes local mucous membrane ulceration and capillary rupture, resulting in bleeding. 2. Pain: the tumor damages the surrounding tissues and involves the nerves, which will cause pain and discomfort in the corresponding area. 3. Mass: with the gradual increase of the tumor, local mass can be felt by palpation in vitro. Some patients may also suffer from fever and abnormal digestive system due to infection. After the clinical discovery of kidney cancer, it is necessary to consult doctor for observation, improve imaging examination and carry out standardized treatment under the guidance of clinicians.
