4 mm lump with circumscribed edges?

[deanna35]

Hello,

I'm extremely nervous about my mammogram and ultrasound I had yesterday. My screening mammogram came back with a request for me to come in for further views of my right breast. After I did that, they performed an ultrasound on that breast. The radiologist told me I have a solid, 4mm lump with circumscribed edges. He told me that it is most likely benign, but that he wants to do a needle biopsy on it sometime in the next 2 weeks. He said that most lumps with circumscribed edges are benign, but he wants to make sure. Is this a typical treatment for a lump this small? I had two fibroadenomas removed from the same breast 20 years ago, and when I lived in California, I was told I had a round lump in the left breast about the size of a small marble, but they just told me to get a mammogram every 6 months to watch for changes in that lump. (It hasn't changed in size.) I'm just anxious because the treatment for these two lumps (the old one from the other breast and the new one in my right breast) has been different.

Thanks for the advice! I just spoke to my doctor this afternoon and he said the same thing as you did, japdip. I'm grateful that my doctor and radiologist are being vigilant and proactive.

Anytime there is the least question as to the exact nature of the abnormality a biopsy is standard treatment. Nothing should ever be left to chance. Radiologists rely on their experience after viewing many thousands of films to determine whether a finding is definitely benign or probably benign. You obviously are having excellent care by a Dr. who is leaving nothing to chance. You are fortunate indeed.  Regards ....
