Does it happen often that a core needle breast biopsy will get nothing or just blood when they go in to get a sample, instead of tissue?

Does it happen often that a core needle breast biopsy will get nothing or just blood when they go in to get a sample, instead of tissue?

It has to get some: tissue. If the doctor happened to get an insufficient sample, he/she would simply take more samples. Sometimes if there is excessive bleeding, the biopsy needs to be stopped, but this would only occur after at least one sample was taken, and it is not a common occurrence. If the lesion is "missed" for some reason, also not very common, the pathology will at least show normal breast tissue. ...Read more

Does a core needle breast biopsy make a tumor smaller or would it stay pretty much the same size but have holes in it from where they took tissue out?

Does a core needle breast biopsy make a tumor smaller or would it stay pretty much the same size but have holes in it from where they took tissue out?

It depends on the : size of the tumor. If it is only 5mm or less, it may be completely removed. If it is slightly larger than that, it may be smaller afterwards. If it is large, the core biopsy will have no perceptible impact on the size. The core bx only removes a very thin cylinder of tissue. ...Read more

Is it normal to have a lump and hardness a week after a needle breast biopsy?

Usually yes: A needle biopsy may result in localized inflammation or a hematome (contained blood) in the area of the biopsy which may feel like a hard lump. If it becomes progressively worse or if you suspect an infection, you need to see your provider. Otherwise it should gradually subside over a course of 2-4 weeks. If it did not go away, you need to check back with your breast care provider to be checked. In addition make sure you get the report of the biopsy to see if there is any concerns abut the result. ...Read more

How can you tell if you had a vacuum assisted breast biopsy or just an automatic gun? They went in, there was a loud sound twice, removed needle,dumped sample out and repeated this a few times.

Whirring sound for several seconds during biopsy. Sample sucked through hose, needle does not need to be removed between biopsies. One exception: Celero vacuum system does not have hose and operates like automated ...Read more
