Q. What is the uncontrolled mitotic procedure that occurs as disease in pluricellular beings called?

Uncontrolled mitotic cell division is known as neoplasia. Neoplasia the formation of new strange tissues occurs when a cell suffers mutation in its genetic material, loses the ability to control its own division and the failure is transmitted to its descendants.

Cancers are malignant neoplasias. The term malignant means that neoplastic cells can disseminate to distant sites invading other tissues and organs. Neoplasias whose cells cannot disseminate to distant sites are known as benign neoplasias.
