Ok so I check my breasts once a week or so because I get afraid because my grandma and a few other woman in my family got breast cancer so I went to do that tonight and this is the rash type thing I discovered under my left breast and very partially under my right. There is a little red bump that feels soft and is kinda inverted, and a bunch of redness, also a white mark that kinda looks like a scar that was not there before either, and two equal tan marks not bumps or anything that are tan and not red or skin toned. Any ideas on what it is and if I should be concerned? Also I am having breast pain but I'm pretty sure the pain is because flo is due in a week and it's my normal pain.
