Hi Iam a female in my fifties have seen a doctor today about a lump in my breast just below my nipple. She said to come back in 3 to 4 weeks if still there. I also have a bruise in the same area. There is no pain but my breast seems larger. I have no idea where the bruise came from. The lump seems to be attached to something at the back of my breast so when I lay down and the flesh moves  the lump and bruise are seperate. Does this make sense?. I once had a lump biopsy years ago which luckily was nothing but at that time my doctor said any lump should be investigated so I'm confused to why I have been sent away to worry.  Can anyone tell me if this is the procedure please.

Thank you
