Re: False negative ultrasound?

Hi Noobster17


Thanks for posting here in the Ask our Nurses area of the forum. 


Thoroughly assessing a breast change is really important to make sure you get an accurate diagnosis of what is causing the lump in case any treatment is required.


Some women do find that the imaging tests they have (mammogram or ultrasound) don’t always pick up or give adequate information on an area of change which can be felt. Doctors would then usually choose to do a biopsy to get a definite diagnosis.


It’s understandable that you are worried about the result, but it’s not possible for us to say what the biopsy will show. However the majority of breast changes in women your age will not turn out to be breast cancer.


Waiting for results can be a really difficult time. You might find it helpful to post in one of the other areas of the forum so other users can share their experience and offer support.

Our free, confidential Helpline is also here if you would like to talk this through or have any further questions. The number is 0808 800 6000. We’re here Monday to Saturday from 9am. On Wednesdays we’re open until 7pm, other weekdays it’s 5pm and on Saturdays it’s 1pm.

False negative ultrasound?

I’m a healthy 33 year old woman and 5 weeks ago, I felt an irregular, rough lump just above my left nipple. My GP was great and referred me straight away to my local breast clinic. I was saw there just over two weeks ago and the nurse specialist thought the lump felt like a cyst (great news!). However, an ultrasound couldn’t detect a cyst or in fact, nothing abnormal within the breast (even better news!). However, the nurse felt a second look by a consultant was needed and saw an amazing doctor yesterday who was concerned enough to do a biopsy. I’m now back on the emotional roller coaster of waiting (and worrying!). I honestly thought the doctor would simply say it was harmless breast thickening etc. I’ve since read that in younger women, false negatives from an ultrasound are not unheard of so now I’m getting worried there is something sinister lurking. Has anyone experienced anything similar? Or could just offer a bit of moral support? Feeling a little lost. Thanks ladies.
