Probably not much good could come of that. So the cell cycle needs to be highly regulated and tightly controlled. And it is.

The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should. Any disruption of the monitoring system can allow other mistakes to be passed on to the daughter cells. Each successive cell division will give rise to daughter cells with even more damage.

Once a proto-oncogene has been abnormally activated by mutation, it is called an oncogene. More than 100 genes have been defined as proto-oncogenes. These include genes at almost every step of the signaling pathways that normally induce cell to divide, including growth factors, receptors, signal transducers, and transcription factors.

It highlights HPV as a biological carcinogen linked to cervical cancer via oncogenes (E6, E7), and details ionizing radiation as a physical carcinogen damaging DNA. Additionally, it covers chemical carcinogens that require metabolism for effectiveness. Overall, reducing exposure to known carcinogens is emphasized as a method to lower cancer risk.

This result is detrimental to the cell and will likely prevent the cell from completing the cell cycle, which means that this cell cannot create daughter cells.
