Hi.   Well, here I am back again.  I was diagnosed with Ductal Carcinoma in my right breast two years ago and I just had my second mammogram since then.  They found an asymmetrical density on my LEFT breast that wasn't there on my last mammo.  I don't know what this is, but I'm sure it's not good.  I have to go for an ultrasound next week.  Can anyone give me any info on this???  Feeling sick all over again.

First, a disclaimer, I'm no expert on this!  However, I did have that term noted on my diagnostic mammogram.  It ended up being the area in which my IDC was eventually found (by ultrasound), but please don't think it is necessarily a bad sign.  I think it just means your breast has a dense area, which the other breast doesn't show, or there are other areas of the same breast that are not similarly dense. If that makes sense.  Sometimes density can hide bad things - sometimes not - or if there is something there, it could be benign too. Try not to worry until you have more information.  Easier said than done, I know. :)

I'm  not an expert either, but here's one person's opinion.


Asymmetric breast tissue is one of the most difficult mammographic findings to evaluate. The breasts tend to be relatively symmetrical in their distribution of fibroglandular tissue. For this reason, mammograms should be viewed so that the right and left breasts can be compared back-to-back on the viewbox. Minor asymmetries in the distribution of fibroglandular tissue between the two breasts are a common normal variant, but moderate asymmetry may warrant further investigation. Further study of a suspicious asymmetric density should include a correlative clinical breast examination (with careful palpation of the area of concern). Depending on the degree of suspicion, follow-up steps might include additional mammographic views, an ultrasound scan, or 6-month follow-up mammography. When asymmetry is associated with architectural distortion, calcifications, or an underlying mass, the probability of malignancy is greater and a biopsy should be considered.top link"http://www.ncbi.nlm.nih.gov/books/bv.fcgi?rid=cmed.section.7013

Here's someone else's view:

"Asymmetric Breast Tissue:
Breast tissue is usually very similar from one side to the other. When a greater volume or density of tissue is present on one side, concern arises even if no mass is seen. Although asymmetry does occur as an occasional normal finding, it is important to obtain detailed views, usually with small "focal compression" devices to spread tissues out and exclude a mass. Even if no mass is identified, accelerated follow-up mammogram in 6 months time is usual. If the area can be palpated (felt), biopsy must be considered. Once asymmetry is identified, it tends to remain constant over years, so comparison with previous mammograms can be reassuring in such cases.

Focal Asymmetric Density:
This is an area of breast density (tissue) with similar shape on two views, but completely lacking borders and conspicuity of a true mass. It must be carefully evaluated with special views (usually "focal compression" once again) to exclude finds of a true mass or architectural distortion. If no specific findings are evident, it is managed as asymmetric tissue, comparison to old mammograms if availible, short interval follow-up if not. If special views show mass like character, or if the area can be palpated (felt), biopsy must be considered."http://radiology.creighton.edu/mammo.htm

You are such a fountain of knowledge, leaf. Love reading your posts! 

It's interesting to learn that my assymetrical breast density - which the most recent radiologist said had been present for "some time" - was never followed up with clinical exam or 6-mos appointment or ultrasound!  Not til I found the lump myself, that is.  Grrrrrrr....

You guys are great.  Thanks for the info.  I spoke with the nurse today and she said my report said 'Nodular Asymmetrical Density".  Does anyone know what this is all about????

Hello There,

Concerning my routine Mammogram- they also found a Asymmetrical Density- meaning an area where they could not tell what was going on. So on 07/29/14- went back for a Diagnostic Mammogram with Ultrasound. First they did the Diagnostic Mammogram- As the breast in question was being placed down on the machine- I felt a horrible pain below my nipple area- So I then had the Ultrasound- I had a bad feeling at this time it was not going to be good news for me.... As the Ultrasound Lady was guiding the instrument over my breast - I was in pain the whole time. She went to go get the doctor to interpret the reading- so as she was continuing - when she came  under my nipple- the doctor let out a gash!! I knew then I had Cancer- she  said it has to be biopsy, I have been my own research tool in terms of my health- and this site has been a wealth of information. I immediately started to ask questions- it measured 2.4cm- stage 2- in her professional opinion. The Biopsy has yet to be done- But the indentation gave it away- I kept thinking well- I have pain.... so it could be the cyst that I always have- but the doctor on yesterday said - that this area is different. I was not expecting any answers on yesterday- But this doctor was a wealth of information-went home and cried!  and trying to get prepared for the biopsy- that will come back with news that I already know. Not saying that every Asymmetrical Density is Cancer- just my experience.
