Cancer cells in urine. Light micrograph of squamous cancer cells in human urine. Malignant cells are large with a pale blue cytoplasm and dark nucleus (hyperchromatic, purple). These cells can divide and grow rapidly. Found in the urine, the cells may have originated from the bladder or the prostate gland. Bladder cancer occurs in 5% of the UK population, affecting three times as many males than females of an average age of 65. Prostate cancer is the most common cancer in men, also occurring in the elderly. Other diagnostic procedures would locate the precise site of the cancer. Stained with MGG. Magnification: x40 at 35mm size.
