Definitions related to carcinoma of bladder:
-
(bladder cancer) Cancer that forms in tissues of the bladder (the organ that stores urine). Most bladder cancers are transitional cell carcinomas (cancer that begins in cells that normally make up the inner lining of the bladder). Other types include squamous cell carcinoma (cancer that begins in thin, flat cells) and adenocarcinoma (cancer that begins in cells that make and release mucus and other fluids). The cells that form squamous cell carcinoma and adenocarcinoma develop in the inner lining of the bladder as a result of chronic irritation and inflammation.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
(bladder carcinoma) A carcinoma arising from the bladder epithelium. Approximately 90% of the bladder carcinomas are transitional cell carcinomas. The remainder are squamous cell carcinomas, adenocarcinomas and small cell neuroendocrine carcinomas.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(bladder carcinoma) The presence of a carcinoma of the urinary bladder.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021

Bladder cancer is a disease in which certain cells in the bladder become abnormal and multiply uncontrollably to form a tumor. The bladder is a muscular organ in the lower abdomen that stores urine until it can be removed (excreted) from the body. Bladder cancer may cause blood in the urine, pain during urination, frequent urination, the feeling of needing to urinate without being able to, or lower back pain. Many of these signs and symptoms are nonspecific, which means they may occur in multiple disorders. People who have one or more of these nonspecific health problems often do not have bladder cancer, but have another condition such as an infection. Bladder cancer develops when tumors form in the tissue that lines the bladder. There are several types of bladder cancer, categorized by the type of cell in the tissue that becomes cancerous. The most common type is transitional cell carcinoma (also known as urothelial carcinoma); others include squamous cell carcinoma and adenocarcinoma. If the tumor spreads (metastasizes) beyond the lining of the bladder into nearby tissues or organs, it is known as invasive bladder cancer.MedlinePlus GeneticsU.S. National Library of Medicine, 2021

Bladder cancer most often causes blood in the urine. To make the diagnosis, a thin, flexible viewing tube (cystoscope) is inserted through the urethra into the bladder.Merck & Co., Inc., 2020
