Kidney tumor
About 95% of kidney tumors are malignant and benign are rare. Malignant kidney tumors can be divided into two types based on the age of onset and the characteristics of pathological anatomy: ① Kidney tumors of young children: mostly called renal embryo tumors, most of which occur before the age of 3 years. According to statistics, this kidney tumor accounts for 20% of malignant tumors in young children. ② Renal tumors in adults: They are more common in women over 40 years of age and more men than women. Cancers that occur in the renal parenchyma are called renal parenchymal carcinomas, and those that occur in the renal pelvis are called renal pelvic carcinomas.
