First of all, bladder tumors are benign. In terms of histogenesis, bladder tumors can be divided into two categories: tumors from epithelial tissue and tumors from non epithelial tissue, namely mesenchymal tissue. According to statistics, 97% of bladder tumors come from epithelial tissue. Bladder tumors from epithelial tissue can be divided into benign and malignant. Benign tumors include urothelial hyperplasia and atypical hyperplasia, papilloma, polyp and adenoma. Malignant tumors include urothelial carcinoma, squamous cell carcinoma, adenocarcinoma, small cell carcinoma and metastatic carcinoma.

Secondly, bladder urothelial carcinoma is the most common, accounting for more than 90% of bladder tumors. Squamous cell carcinoma of the bladder is rare, accounting for 3% - 7% of bladder tumors. Bladder adenocarcinoma is more rare, accounting for less than 2% of bladder tumors. Bladder adenocarcinoma is the most common cancer in patients with bladder valgus. Non epithelial bladder tumors mainly come from muscle, blood vessel, lymph, nerve and other tissues, accounting for only about 4% of bladder tumors. It is also divided into benign and malignant. Benign tumors include leiomyoma, rhabdomyoma, hemangioma, fibroma, pheochromocytoma, lipoma, myxoma and osteoma. Malignant tumors include leiomyosarcoma, rhabdomyosarcoma, carcinosarcoma, malignant lymphoma, malignant melanoma, fibrosarcoma, bone and chondrosarcoma, etc.
