I hope someone might be able to help. For the last 4 months I have had developing bumps on my chest . The don't want to go away or even heal. They are all in a perfect triangle on my chest the biggest was the first and then a couple others appeared later. They are all raised and they don't hurt to touch and some of the skin is more shiny in that area. I wonder if they are some sort of melanoma any suggestions would be appreciated.
