Cancer as Uncontrolled Cell Division
Captions available
The idea
Cancer is a family of diseases sharing one mechanism: uncontrolled cell division caused by a breakdown in the cell cycle's regulatory checkpoints.
In practice
A single small replication error, uncorrected and passed to daughter cells, can compound across many divisions until checkpoint control fails.
Where people slip
A single mutation rarely causes cancer outright — the disease typically results from accumulated errors across many cell generations.
