The tests may find that there is no problem with the breast tissue. This means that the first mammogram showed an abnormal area in the breast, but further tests didn’t find a problem. The first mammogram is called a false-positive result. You won’t need to have any further tests or treatment and can go back to the screening unit for a routine mammogram in three years’ time.
Many false-positive results are due to tiny deposits of calcium in the milk ducts, known as microcalcification. Microcalcification occurs in many women over the age of 50 and is usually harmless.
