Hi from few days I find some changes near my breast don't know if those are due to bra fitting or something else. I donot know how to describe but they look like stretch marks. I don't know if those are serious I am very much worried I have left hand pain from few days. Found these stretch marks which are not clearly visible but I can feel them. Is it breast cancer symptom. In net it shows dimpling how dimpling looks is this dimpling. I am 30f plz help me i am very much scared. No lump or any other changes yet.
