Doesn’t the heart have enough problems

?!?!
Cancer occurs when cells grow out of control. Probably, cells in the heart and the vessels, are not reproducing and growing very much (in contrast to the rapid turnover of epithelial tissues in the skin, gastrointestinal tract, and other organs). There is a science fact that heart cells divide only maybe once a year.
So, no division, no cancer.
Do you have personal experience with heart cancer?
