I have this mark on my breast for about 3 years now. I've always been too awkward to ask my doctor about it (stupid, I know). It was caused by a pimple I had there and I impulsively pick at spots. It's about 3cm big and not sore to touch. Does anyone know what it is and could it be removed as I'm going on a beach holiday for the first time in about 10 years and I'm self conscious about it now. Any help would be appreciated!
