Respuesta :
Yes we would want to know.....for example...if my family had cancer...then I am aware that I would get it and take medication before its too late!
This question is mostly opinion based, so it wants to know what you think. for example, the other answer would want to know because they find it helpful, but I wouldn't want to know because it's not guaranteed you will develop those conditions and I know myself well enough to know I would get paranoid. Hope this helps!
