A mammography technologist uses specialized equipment to study abnormalities in breast tissue. Mammography technologists often complete training that is similar to radiologic technologists to increase their proficiency in operating X-ray imaging equipment. Mammography technologists assist with assessing breast tissue health, performing diagnostic exams, and producing the images that physicians need to update patient medical records. A mammography technologist is also responsible for answering patient questions, to include advising patients on how normal breast tissue looks and feels compared to abnormal breast tissue.
