I have had a lump in my right breast since I was 21 (I am now 35 years old) was told a 'breast mouse' because it was moveable apparently and nothing to worry about. However, when I had my daughter 2 years ago I noticed it had enlarged again. Went back doc, sent to hosp and told me I was misdiagnosed 12 years earlier and it was actually an enlarged lymph node, had to have a needle aspiration taken from it (would have preferred biopsy) given all clear 2 years ago. Just found another lunp underneath original lump and some thickening to breast tonight. I am most concerned that because they did not biopsy it something is seriously wrong. I have been through this worry 3 times already and it certainly doesn't get any easier, think I am going to push for a biopsy this time as can't take the worry anymore.
