A gene that has mutated and starts contributing to the development of cancer is known as an oncogene. When these oncogenes are in their normal state, they are termed as proto-oncogenes and they are responsible for controlling and regulating the process of cell division. They also play a significant role in cell death during the growth and development of cells.
But when it attains a mutation or the cell has started making extra copies of these proto-oncogenes, then they become hyperactive and resultantly cause uncontrolled division of cells. Hence, they contribute to the formation of cancerous cells.
