I have within the past 2-3 months had a spot in the center of my chest that itches horribly every so often. At other times its fine. its kind of a light red color and there are spots scattered around it. It's Darker than my light tan colored skin though. I am 23, male, 5' 7". My mom has breast cancer and my uncle MAY have had cancer we don't quite know because he's secretive. I scratched it a bunch and it started to bleed at one point. After it scabbed up and went away it got lighter and now its darker again. It also has a clear colored liquid that could just be plasma because of the scratching, coming from the pores.
I pored hydrogen peroxide on it and it burned alot and turned yellow for about 5 minutes. May or may not have had parts turn white. It was hard to tell after I flushed it with water, may have just been remnants of the peroxide.
Anyway, it is concerning me because my mom just got diagnosed, but I don't want to jump to conclusions, or pay money that I don't even have to see a doctor and have him say it will go away...
