Today I had a core needle biopsy done and the doctor was having trouble extracting a sample. She tried four times with the needle and it wouldn't go in. She put on a different needle and was still having difficulty because the lump was too hard. She said that for this to happen it was rare. She was trying to get samples from the center of the lump but the needle kept on bouncing off the center. She ended up getting 3 samples but they were from the outer edges when the needle would slip off the center area. She originally figured the lump was just breast tissue or fat necrosis prior to the biopsy because I had breast reduction surgery in that area one and a half years ago. I am just wondering if anyone else has had a core needle biopsy where they had problems getting a sample because the lump was so hard? Thanks in advance :-)

When I had my core biopsy done it sounded like a drill. Kind of like a roto rooter to get the sample. Was she trying to aspirate the lump?

She inserted the needle and it was like a staple gun, lol! She was just trying to get samples from the lump using ultrasound guided and the needle wouldn't go into the lump and kept slipping off. She was able to get 3 samples and put them on slides but it was from the outer edges after the needle slipped off the center.

Greenshamrock - Yes.

Can't remember if it was my first US-guided core needle biopsy or my second one, that I heard the Radiologist (AWESOME woman) say "Darn it!"

She said she was having trouble getting the needle to go into the mass....that it was acting just like a fibroadenoma, and was bouncing off the needle like a rubber ball.

She finally did get enough samples (4 or 5) to make a positive dx.

Turns out I had DCIS, with a microinvasion of IDC. When I got my final path report, there was NO EVIDENCE of the IDC...they said it was so small, the core-needle had gotten it all.

sewingnut - All I heard with my CNB was loud snapping sounds as the little tool kept taking "bites" of tissue out of the mass. Fortunately, the lidocaine had worked really well!

Yes, I had the same problem. My Dr is a female and she actually had to put her knee on the bed so she could push down to get inside. I was sooooo bruised after. She thought it was a fibroadenoma but unfortunately it was not. Im hoping you have b9 results.
