Hi I know it's a worrying time , I had my appointment one week after being referred by my GP I suppose it depends on where you live. You will sit with a consultant who will go over your symptoms and family history and then have an examination. Depending on how that goes you will most likely be offered a mammogram/ultrasound if necessary and there is still further information needed they will perform a biopsy there and then. The results of the biopsy takes a further 10 days. Hope this helps and best of luck.
