Rash Near Breast

I'm 18 and I have had this tiny lump, which is almost gone now inbetween my two breasts.  I aslo have this rash inbetween my breasts.  I wanted to know if this is a sign of cancer.

Thank you.

Dear Sarah, This rash sounds more like some type of skin irritation, and not a sign of cancer.

I have a rash on the side of my breast that is in the shape of Parentheses. Do you know what this might be?

I have a rash on the outside of my areola. My doctor said it was ok, but it has gotten bigger. When I checked it out, ther is still no mass or lump, but I am worried.
