Cancer cells are characterized by uncontrolled cell division, often due to mutations in genes that regulate the cell cycle. Unlike normal cells, cancer cells can bypass the usual checkpoints that control cell growth and division. They may also avoid apoptosis, the process of programmed cell death, which allows them to survive longer than normal cells. Additionally, cancer cells can stimulate angiogenesis, forming new blood vessels to supply themselves with nutrients, and they can become metastatic, spreading to other parts of the body.
