(1) I will pray for you both (and anyone else awaiting scan results), that things turn out to be non cancer related.
(2) If the diagnosis is not good, try not to project forward, because you will just torture yourself, and block out the good stuff in you life. The fact is that once you have a cancer diagnosis (whether primary or secondary), there is no way of knowing what the future holds (and if everyone went through life worried about what could happen, it would spoil day to day existence). Neither should you attempt to sugar coat things for others, because that will only generate confusion/more questions. You will then find yourself constantly comforting others, when it should be the other way round - and worse re-living the diagnosis, when what you need most, is to come to terms with, and learn to live with it.
