Bladder cancer cell. Coloured transmission electron micrograph (TEM) of a section through a bladder cancer cell. The cell is large and has many nuclei (purple). This is typical of the chaotic and disorganised growth of cancers. Bladder cancers usually arise in the internal lining of the bladder. Symptoms include blood in the urine. Treatment involves excision of affected tissues, and then chemotherapy and radiotherapy.
