What are the causes of kidney cancer?

Renal

cell carcinoma is a malignant tumor that originates in the urotubular epithelial system of the renal parenchyma. It is also the most common renal parenchyma cancer. Like other malignant tumors, renal cell carcinoma can metastasize by direct invasion of the lymphatic system and the blood system. Lymph node metastasis occurs first to renal pedicle lymph nodes, and blood metastasis sites include lung bone, liver, adrenal gland, and brain. Advanced renal cell carcinoma mass can invade retroperitoneum and peripheral nerves, oppress surrounding tissues, cause pain, edema of lower limbs; cough, expectoration, hemoptysis, etc. can occur when lung metastasis occurs; pathological bone fracture can occur when bone metastasis occurs? Clinically, there is no saying that renal cell carcinoma is not easy to metastasize.

When entering advanced renal cell carcinoma stage, the main treatment goal is to prolong survival time and improve quality of life.
