But cancer isn't primarily a genetic problem; it's a consequence of the way our bodies work at the cellular level.
We all accumulate genetic damage over time from a variety of sources, and we'll all get cancer eventually if something else doesn't kill us first.
That is the story for most people today but is not the entire story. If your mother had breast cancer then you are at a higher risk - if not for genetics that would be magic. That is why I specifically said "hereditary cancer."
