This leaflet provides information on the tests that can take place at the hospital to establish the nature of the abnormality. You will have received your results letter from the breast cancer screening programme. The radiologists have found an abnormality on your X-rays but they do not yet know precisely what it is. Whether it is a benign or a malignant condition can only be determined after further tests at the hospital. About two out of three women referred for further investigation are found to have a benign abnormality. We have already informed your GP of the results. If you have not been in touch with him or her yet, we would advise you to make an appointment.
