Another referral

Hi all
I had a fibroadenoma removed in June 2011, and over recent months have been having unpleasant pain in the same breast - but in a different area. This breast is very nodular and I can feel a number of lumps. I went to my GP this morning just to get advice really, but have been referred to the clinic again. I was wondering why I might have been referred again and whether or not the mini-pill can cause changes like this?
Many thanks in advance for the advice!
