Mammography and breast ultrasound may not result in a clear diagnosis. Given unclear changes of the breast, a biopsy, a sampling of tissue of the affected area, is then necessary to clarify a diagnosis.
Afterwards, the tissue sample is examined by a pathologist who makes a diagnosis. The results are often available one or two days after the biopsy.
Although changes of the breast have been diagnosed malignant as a result of radiological examinations, it still makes sense to ensure the correct diagnosis by a biopsy. It determines the kind of treatment that cures the breast disease the best.
During biopsy, the correct position of surgical instruments is always controlled by a radiological examination device. If the change of the breast is visible during an ultrasound examination, the tissue will be sampled while performing an ultrasound examination. If it is visible only during mammography or MR mammography, the tissue will be sampled while performing the respective radiological examination.
