Human cells divide to create new cells. This process is called mitosis. Atypical mitosis is an abnormal dividing cell. As a result of this abnormal cell division, the newly created cells receive an unequal amount of genetic material (DNA) and are unable to function normally. Atypical mitoses are commonly seen in cancers; they are rarely seen in other conditions, such as tissue that has been exposed to radiation. Another name for atypical mitosis is atypical mitotic figure.
