Core needle and stereotactic breast biopsies may leave a
small round scar. Open biopsies leave a small straight line scar. The scar
fades over time. A fine-needle biopsy usually does not leave a scar.

ductal hyperplasia, or ADH); or changes in the breast tissue cells called
columnar alteration with prominent snouts and secretions (CAPSS). If ADH is
present, an open biopsy is needed to make sure there is no cancer.

What Affects the Test
A needle biopsy takes tissue
from a small area, so there is a chance that a cancer may be missed.
What To Think About
Most breast lumps are not cancer. But the chance of having a
cancerous breast lump is higher after menopause than before menopause.
Some lumpiness of
breast tissue is normal. The fibrous tissue in the breast often feels lumpy or

change) is so common in women that doctors now think it is a normal change.
These changes usually go away after
menopause, but they also may be found in women who are
hormone replacement following menopause.
