Understanding Breast Density - Professor Wendy Ingman

Mammograms are a fantastic tool for identifying many breast cancers - However, having Dense Breast Tissue can result in a later diagnosis as tumours don't always 'show' on 2D mammograms for women with more dense breast tissue, until they are larger & more dangerous.  Sometimes dense breasts are also called 'lumpy breasts'.    Mine were - but I was never told of the increased risk of delayed diagnosis of Breast Cancer.  My own tumours were found 4 months after a 'clear' mammogram - when my GP suggested she check my breasts.

Breast Density 'masks' Breast Cancer.  A delayed diagnosis can lead to larger, more dangerous tumours and may even be Stage 4 at diagnosis due to not being picked up on previous mammograms (and I'd had about 10 - as I'd been 'called back' a few times, but never really told why.) 

Dense tissue shows as 'white' (or occult) on the mammogram, and tumours show as 'white' as well.  

White on White = unable to detect the tumour with a 2D mammogram.  (3D Tomosynthesis machines are better at picking up dense breast tissue - but are not commonly available at Breast Screen clinics.)

There is a need for Breast Screen clinics to advise women of their breast density - but currently only Western Australia Breast Screen actively advises their clients of their breast density.   

An Ultrasound is recommended for anyone with dense breast tissue - and biopsy on any suspect areas.  Tell your daughters, sisters & any other woman who SHOULD KNOW THIS as a 'right'!!

  • I have always had dense breasts, but have noticed a change in them since being on chemo.
    It seems like my remaining boob is softer and floppier than it used to be.
  • I'm getting older & mine are still dense. 

    I didn't have kids either - apparently having kids makes them less dense as well

    I don't think they really 'know', to be honest
  • My surgeon says all breasts get less dense as we age - mine is apparently transparent! 
  • Wendy mentions the change in breast density thru the years - also relative to having children and aging.

    It can be hormonal as well as genetic, I think - hence women on HRT have a higher chance of BC as their hormones have been manipulated.   

    I was on hormone cream for some months in my 50s & had a mammogram at that time - and received a callback to the local bus, then to the closest town ..... then to John Hunter Hospital in Newcastle!  It was believed to relate to the testosterone component of the cream!  I stopped the cream as soon as I got the callback to John Hunter & by the time I was checked again there - it had gone back to relatively normal again!  (No mention of dense breast tissue there, either, even tho a specialist had told me in my 20s that my breasts were 'lumpy'!)


  • So true Arpie, I found this out about 14 years ago from my Sister when she was diagnosed with BC.  She has dense breasts, her mammogram was clear and it was only detected by ultrasound.
    I had to have my mammogram around the same time and asked if I have dense breasts, yes. So I had an ultrasound also- recommended by my GP.
    Funny thing is, this time around my Surgeon said my breasts are no longer dense, I did not know that was even possible?
