Answer:
The correct answer is - Uncontrolled mitosis of cells.
Step-by-step explanation:
Cancer is nothing but a failure of a mechanism that controls the mitotic cell division and leads to uncontrolled cell division. Cancer is developing abnormal cells that divide uncontrollably and can be spread into neighboring tissues, or organs.
It is occurred in mitotic or somatic cells by the mutation or changes in the DNA present in the cell. These section of DNA termed as gene and these genetic change in the gene leads to failure of a gene or the mechanism that control or kill the abnormal cells.
