Pimple..? Under breast?

The flash makes it look extra shiny.

The second picture is without flash.

This has been under my breast for about 2 weeks, I just noticed it aproximately 2 weeks ago. I'm not really sure what it is, had has anyone had this before?

Kind of scared it could be a sign of breast cancer. It probably isnt but i dont know..
