Hi I just discovered these four flat bruises on my breast they don't hurt and are flat. One is a dark purple and the rest blue ish. I don't recall bashing myself or hurting/straining. My husband thinks they could be burst blood vessels/small bleeds under skin . I'm going to try and book an app But wondered if I should be worried? 
I'm only 22 and have no history of breast cancer in family. Help :( xxxx I've had to post the image as my profile picture as I couldn't upload it through here
