Kidney cancer is the abbreviation of renal cell carcinoma. Clinically, part of renal pelvic cancer is also called renal cancer, but the treatment of renal pelvic cancer and renal cell carcinoma is completely different. 1.Kidney cancer is a common malignant tumor of the urinary system, accounting for about 2%-3% of adult malignant tumors and 85% of primary kidney malignant tumors. The high incidence age of kidney cancer is 50-70 years old, and the incidence rate of men and women is about 2:1. The incidence of kidney cancer in big cities is on the rise, and patients under 50 years old are not uncommon. 3.The early symptoms of kidney cancer are not obvious, and patients often find it during physical examination or examination of other diseases. 4.Kidney cancer originates from renal tubular epithelial cells, and the pathological types can be divided into clear cell carcinoma (80%-90%), papillary renal cell carcinoma or called chromophobe carcinoma (10%-15%), suspicious cell carcinoma (4%-5%), collecting duct carcinoma and unclassified renal cell carcinoma. 5.Diagnosis relies on auxiliary examinations such as ultrasound, X-ray, CT, MRI, angiography, but the final diagnosis still needs pathological confirmation. 6.The effective treatment methods of kidney cancer include: surgical resection, immunotherapy, targeted therapy, minimally invasive interventional therapy, Chinese medicine treatment, etc. Most of kidney cancers develop slowly and can have a long survival period with active Chinese and Western medicine treatment. Its prognosis is related to tumor size, number of months, pathological level and especially infiltration range. The inherent host immune function of human body plays an important role in the development and regression of kidney cancer, therefore, kidney cancer is one of the diseases that are more sensitive to immunotherapy and better for the first time. The application of TCM kidney tonic treatment after radical surgery can improve the host’s ability to monitor tumor and reduce recurrence and metastasis; for advanced stage patients, TCM kidney tonic treatment can prolong survival, relieve symptoms and stabilize the disease.
