Needle aspiration A thin needle is inserted into the breast in the area of the lump, and some cells are drawn out. This may be done at the same time as the ultrasound, so that the doctor can be sure that the cells are from the affected area of the breast. The cells are examined in the laboratory to see if any are cancerous (malignant).

Needle biopsy A small sample of tissue is taken from the breast with a needle and examined under a microscope to check for cancer cells. An injection of local anaesthetic is given to numb the area before the biopsy is taken.

Blood tests These are done to check your general health before any operation.
