- So cancer cells actually come from
just your normal, healthy cells that have mutated in some way.
- Every time your cells divide,
you have trillions of cells in your body,
they make mistakes every so often.
And most of the time, those mistakes are benign,
so they don't hurt you and they don't turn into cancer.
But probabilistically, every so often,
one of those mistakes is a malignant mistake,
and it turns into cancer.
