True or False Multiple changes in DNA are required to change an abnormal cell into a cancer cell?

True.

Multiple changes in DNA are required to change an abnormal cell into a cancer cell. This is because cancer is a complex disease that involves many different genetic changes. These changes can affect genes that control cell growth, division, and death. In order for a cell to become cancerous, it must acquire a number of different mutations that allow it to escape from the normal controls that govern cell growth and division.
