Dilated Milk Duct?

[Julie B]

Five years ago, I wrote into this forum after finding a hard palpable lump.  At thatime, I had had a mammogram with spot compression, and an ultrasound of the breast.  The lump I can feel did not "image" on either test.  I came to the Breast Clinic at Cleveland Clinic for a 2nd opinion, and both tests were repeated with the same result.  The doctor felt that I possibly had a dilated milk duct.  I left a bit confused as to what that meant, but basically satisfied that the lump was nothing to be concerned about.  I've continued my yearly mammograms, and every one has come back normal.  Last month, when performing my self exam, I noticed that the lump felt bigger - it never went away in all of these years.  I went to my OB GYN, who referred me to a surgeon, because he felt that it needed to come out.  Upon scheduling my referral, the scheduling nurse decided that I should have another ultrasound, being that my last one was in 2003.  She also suggested that I get a breast MRI, prior to going to the surgeon.  My question is this:  If in fact this is a dilated milk duct, would it get bigger?  I am a 45 year old, and I have been on the Pill for the past 3 1/2 years to control ovarian cysts.   I would definitively like to know whether this lump is a reason for concern or not.  Everyone who has examined me can feel the lump, so I know I'm not crazy.  Thanks for any info you can provide on the subject.

Can anyone tell  me what a single focally dilated duct to the inferolateral aspect of the nipple means this was the ultra sound and mammogram findings for me. Went back to the GP to be told not to worry but not given a reason why this duct would be dilated

Hi there.

I understand your concern.  Breast ducts can have the capacity to enlarge and dilate but what is important is to determine the reason or mechanism for such.  Some causes of enlargement of these ducts would include accumulation of the natural breast fluids or secretions, or more importantly the presence of hyperplasia (increased number of cells comprising the ducts).  I agree with the surgeon consult, the repeat ultrasound and possibly the MRI.  A fine needle biopsy may also be warranted to determine the exact nature of the lump.  Regards and God bless.
