Re: Little lump on arm
It's likely just a tiny lump of nothingness. I've had this fear pop in my head occasionally, but the thing to remember is, the skin isn't porcelain; it isn't perfectly smooth and most lumps, bumps, moles, tags are perfectly harmless. The things you've mentioned to look out for, are what most people look out for. But my understanding from somebody I know that had SC was; they noticed a growth, it continued to change/grow pretty rapidly and it wasn't easy to ignore. It was removed and that was that, they are good and rocking out.
To quote Fishmanpa...
"Cancer is an uncontrolled growth of abnormal cells. It doesn't come and go nor does it stop once it starts"
