Cervical cancer. Coloured scanning electron micrograph (SEM) of a cervical cancer cell in the final stage of cell division. The cell has divided to form two daughter cells, which are linked by a cytoplasmic bridge (centre). The cervix is the neck of the uterus. Most cervical cancer arises from the flattened cells that cover the cervix. It may take years to develop but will then spread rapidly to nearby tissues and other organs. In the later stages, symptoms include vaginal discharge, bleeding and pelvic pain. Advanced forms of cervical cancer may be treated by surgical removal of the uterus and the ovaries.
