Prostate cancer. Freeze-fracture scanning electron micrograph (SEM) of prostate cancer. The spherical glandular acini (for example at lower right) are lined with carcinoma cancer cells. Prostate cancer is one of the most common male cancers, usually affecting the elderly. The uncontrolled growth of the cancer obstructs the neck of the bladder, impairing urination. Treatment involves surgery to remove the prostate gland or radiotherapy. Magnification: x800 when printed at 10 cm wide.
