Hallo. I am 45 with 2 teenage children. A few hours ago I discovered a strange large lump in outer side of my right breast. It's massive - the size of a walnut - and feels like it's just under the skin. Now I think about it, I've had a couple of times recently where this breast has felt hot and itchy - I think it could be related. I've been looking online at breast cancer sites and am now in full panic-mode. I'm obviously going to see the GP on Monday, but in the meantime have gone into a weird state of shivering and crying and imagining horrible scenarios. I can't sleep. Please could somebody reassure me that it is probably something harmless...
