Cancer may result if DNA damage is not repaired. The Greek physician Hippocrates used the term carcinoma (from the Greek karcinos, meaning “crab”) to describe tumors. Like crabs, some tumors have a shell-like surface and leg-like filaments. The image shows a colored scanning electron micrograph of a cervical cancer cell. This large rounded cell has an uneven surface with many cytoplasmic projections. Cervical cancer is one of the most common cancers affecting women.
