1. Why we don’t hear much about heart cancer? Is it possible for hearts to get cancer?
It turns out that heart cells rarely need replacement at all. The fewer times the cells need to be replicated, the lesser chance there is for cancer cell mutations! Unlike heart cells, however, cells in the colon and lungs often need replacement due to the constant external stimuli. The likelihood of mutation, therefore, becomes higher, so there is a greater chance that the cells could develop into carcinoma in situ and malignant tumours.
