There is nothing qualitatively different about your cancer cells and your regular cells. That's why it's so hard to treat cancer. Yes I am concerned the genes that modulate cell division are not working as well as previously and I agree this is a concern. I would not be shocked to discover that it's true. But this is not a new thing. Cells that divide have been able to divide since the dawn of time. If your concern is that a cell will excessively divide, then say that, instead of a buzz word like "cancer"

I have no idea where you came across that word, but when I see it used, there's generally a lot of handwaving and some vague implication that it's bad. The only consistencies I've observed in attempts to define it is that cell division = cancer or "uncontrollable replication" = cancer, and the speaker is generally uncomfortable with cellular natural selection as a driving force behind evolution.
