Essential Question What is uncontrollable cell division? Standard B.5D – Recognize that disruptions of the cell cycle lead to diseases such as cancer Pg 55

Cancer is a disorder in which some of the body’s own cells lose the ability to control growth.

Cancer cells do not respond to the signals that regulate the growth of most cells. Cancer cells divide uncontrollably and form masses of cells called tumors. Tumors are harmful because they damage surrounding tissues.

Cancer cells may break loose from tumors and spread (metastasis) throughout the body.

Cancer may be caused by tobacco, radiation, or viral infection. All cancers have one thing in common: The control over the cell cycle has broken down.

A large number of cancer cells have a defect in the p53 gene. The p53 gene normally halts the cell cycle until all chromosomes have been replicated.
