In cases when the tumor is very small, contains so-called “microcalcificates”, does not show on ultrasound but is detected on mammograms, a diagnostician performs stereotactic biopsy which means an X-ray-controlled biopsy. Special equipment is employed which includes a self-guidance system of the biopsy needle controlled by two X-ray devices.
These devices create a three-dimensional image of the breast with a suspicious neoplasm and ensure the needle accurately hits the suspected area. X-ray control of a piece of removed tissue is also performed to confirm the accuracy of the biopsy. This procedure can often prevent unnecessary surgical intervention and discard suspicion of oncological pathology.
