Skin lightening for uneven skin tone

I have 3 spots on my forearm; I've had them over 5 years. In the interim,I had two blood tests for cancer, which have been negative. Two spots are light brown and the size of a pencil eraser. The one in the middle is not quite dime-sized, but it is brown to reddish brown on the outside. They are all flat. The larger one has bled before. Is this normal? Do liver spots ever bleed? Should I be concerned?
