What are the dangers of advanced kidney cancer

What are the hazards of advanced renal cancer: Renal cancer is a malignant tumor originating from the renal parenchyma urinary tubular epithelial system. The full academic name is renal cell carcinoma, also known as renal adenocarcinoma, or simply kidney cancer. It includes various subtypes of renal cell carcinoma originating from different parts of the urinary tubules, but does not include tumors originating from the renal interstitium and renal pelvic tumors.

1. Hematuria: Normal people will not have hematuria, but it is the main symptom of kidney cancer patients. About 40% of kidney cancer patients have hematuria, which can be macroscopic hematuria or microscopic hematuria. When there is a large amount of hematuria with blood clots, renal colic, urination pain, dysuria, and even urinary retention may occur.
2. Lump: Kidney cancer is a malignant tumor, and because it is close to the waist, the lump can be clearly felt. The kidney is located deep behind the peritoneum and cannot be felt during abdominal palpation. The lump can only be felt when the tumor is large or located at the lower pole of the kidney, and sometimes it can be the only symptom.
3. In addition to hematuria and lumps, kidney cancer also causes pain. Severe pain is the biggest hidden danger for kidney cancer patients. Low back pain is caused by the increase in the tension of the renal capsule or invasion of surrounding tissues after the tumor grows. It manifests as persistent dull pain. Tumor bleeding causing subcapsular hematoma can also cause dull pain or dull pain. Tumor invasion of adjacent tissues and organs such as the psoas major muscle or nerves can cause persistent and severe low back pain.
