I have a light brown mole that's on the lower, inner thigh of my right leg and I've had it since I was a child with no changes. It is 3/8 th of an inch by 1/4th of an inch and while I was pregnant, it split in the middle and got some white, raised areas. they feel like medium sized pimples that will not go away, and that was 3 years ago. Tonight, I noticed that I got a few more there. I din't know when, but it was within the last week or two. I also have a very dark mole on my bottom that was a scab like blod blister that appeared during my first pregnancy, that I thought must have happened from pushing in the delivery room and didn't notice it till two or three days after the birth. It looked like a bubble of purle, thick blood, and was just like a blood blister. I gave it some time to heal and then it dried up enough to peal it off and I did, and there saw dark pink skin under it, then a few weeks later, I noticed an almost black, mole there about 2/3 the size of a pencil eraser. It hasn't changed at all since it appeared 3 years ago. Do you think these are cancer ? If so, what kind and how much is the treatment? Thanks for your help.
