i'm a little worried too about a hard lump that is growing on my breast bone between my right breast and my left masectomy reconstruction site...i'm hoping like you that someone else has had this and can put my mind at rest. My doc said i should hear from the breast clinic yesterday or today...still waiting.
I have a lump in same area and am waiting for my appointment at the breast clinic on 28 December. When I went to see my own doctor after finding the lump quite by accident (it can only be felt when I lie down) he said he thought it "felt like a cyst" and not to worry - so I'm trying not to worry (I have had a cyst before in the other breast about 6 years ago which felt different). I found this one nearly a month ago and it doesn't seem to have grown in size since then which I'm hoping is a good sign. I hope everything goes well for you when you have your examination.
I'm 42. About a week ago i noticed a bean-sized hard immovable lump in the centre of the chest, between the breasts. It feels oval and smooth and is sore. I have a GP appt on friday, but just wondering if anyone had had anything right in the middle like that, and could shed any light on it.
