Learning Objective
I can describe how uncontrolled cell growth leads to cancer.
- 1
A multicellular organism grows by cells making more cells through cell reproduction, such as mitosis and cytokinesis.
- 2
Cancer can occur when cells divide too frequently and are uncontrolled, possibly due to genetics, toxins, radiation, or UV light exposure.
- 3
The cell cycle includes interphase, where cells grow and replicate DNA, and M phase, where cells divide through mitosis and cytokinesis; checkpoints ensure the cell is ready to divide, and if not, apoptosis may occur.
