The enemy within

It struck me the other day that being told you have cancer is a bit like a woman being told she is pregnant. Suddenly, you are aware that something, unseen and unfelt (initially, at least), is growing inside your body – something that is not you. Beyond that, of course, the comparison fails. Pregnancy means the beginning of a life; cancer, all too often, means the end of one. Still, the initial sensations must be rather similar.
