What are the dangers of having kidney cancer?

Kidney cancer is one of the tumor diseases that seriously endangers people's lives and health. Its clinical symptoms are varied and difficult to diagnose and treat in the early stage. Therefore, we need to fully understand the symptoms of kidney cancer, pay attention to it, and do regular physical examinations to avoid the occurrence of kidney cancer to the greatest extent. So what are the dangers of kidney cancer?

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. About 10% to 40% of patients can feel an abdominal lump, which can sometimes 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 occurs when the tension of the renal capsule increases or invades surrounding tissues after the tumor grows. It manifests as persistent dull pain. Tumor bleeding causes subcapsular hematoma and 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. The incidence of pain is 20% to 40%. If you have related symptoms, you should seek medical attention in time to avoid delaying the disease.
