Yesterday, (while scratching), I found a little pointy-feeling lump in the lower half of my left breast. I have lumpy breasts in general and have had several ultrasounds/mammograms in the past to rule out any problems. But my normal lumps are deep-down and smooth.
This one feels different to that, it feels kind of grainy, and is much closer to the surface, more under my skin. With the others I have to press quite hard to feel them, but this one is just there, and I can feel it with almost no pressure at all. What's of real concern is that it feels hard, like a stone, I know that soft, movable lumps are less likely to be cancer.
I've managed to get a doctor's appointment for tomorrow, and I'm sure they'll refer me to get it checked, but I'm obviously worried and want to try not to spend the whole day panicking.. Arghhhh!!! Might bake a cake to take my mind off of it. 
I know that nobody can diagnose me on the internet, but I wanted to tell someone about it as I haven't told anyone yet.
