What are the key differences between normal cell division and cancer cell division?

Normal cell division is tightly regulated and controlled by the body to ensure that cells divide at the right time and in the right amount. In contrast, cancer cell division is uncontrolled and can happen rapidly and uncontrollably, leading to the formation of tumors. Additionally, cancer cells can invade nearby tissues and spread to other parts of the body, a process known as metastasis, which normal cells do not do.
