Type:
Normal cells grow and divide in a regulated manner through the cell cycle, which consists of phases (G1, S, G2, and M).
Cancer cells often bypass these regulatory mechanisms, leading to uncontrolled proliferation. This can result from mutations in genes that control the cell cycle, such as oncogenes (which promote cell division) and tumor suppressor genes (which inhibit cell division).
