A finding about one or more characteristics of bladder cancer, following the rules of the TNM AJCC v8 classification system. This classification system applies to carcinomas arising in the bladder. The typical carcinoma of the bladder is urothelial carcinoma. These carcinomas may include other histologic elements, including adenocarcinoma, squamous cell carcinoma, and small cell neuroendocrine carcinoma, but should be classified as urothelial unless the cancer is composed entirely of the alternative histology. All histologic cell types that are derived primarily from the urinary bladder epithelium should follow this classification system. It does not apply to prostatic urothelial carcinomas (are staged according to the classification for urethra), lymphomas (are staged according to the classification for Hodgkin and non-Hodgkin lymphoma), and sarcomas (are staged according to the classification for soft tissue sarcoma of the abdomen and thoracic visceral organs).
