Why do cells mutate and multiply uncontrollably?

Cells can mutate and multiply uncontrollably due to various factors, including genetic mutations, exposure to carcinogens, and viral infections. These mutations can disrupt normal regulatory mechanisms that control cell growth and division, leading to unregulated proliferation. Additionally, inherited genetic predispositions can increase the likelihood of such mutations, contributing to the development of cancers and other diseases. The accumulation of these mutations over time can result in the formation of tumors and other pathological conditions.
