Cell Cycle Checkpoints and Cancer

Diagram comparing normal cell cycle with functional checkpoints (G1/S checkpoint checks DNA damage, spindle checkpoint ensures proper chromosome attachment) versus cancer cell cycle with failed checkpoints allowing damaged cells to proceed through division

Figure: Normal cell cycle checkpoints prevent damaged cells from dividing, while cancer cells have dysfunctional checkpoints.

What is cancer?

Cancer is a group of diseases involving uncontrolled cell division, where cells divide continuously without normal restrictions.
