First, and foremost, most diagnoses can and should be made via a needle/core biopsy. With rare exception, one should only go to the operating room AFTER a diagnosis is made and with a plan of what needs and will be done.
In a core biopsy, the needle has a sampling tray and a there is a cutting blade or cannula that passes over this to take the sample. In a vaccum assisted core biopsy, the vacuum pulls tissue down into the sampling tray improving the quality and size of the specimen retrieved. The vacuum may also be used to pull the tissue out of the needle readying the sample tray for the next tissue acquisition (rather than removing and re-inserting the entire needle/device). In the case of a benign but palpable lesion (i.e. fibroadenoma), with enought samples, most or all of the lesion can be removed with a vacuum assisted device rendering it no longer palpable.
