A radiologist determines the density of a woman's breasts by examining a mammogram. If you still feel the need for a mammogram, request a copy of your mammography report from your referring doctor. Make sure it is the report that is generated from the radiologist and not a form letter. Read the report carefully. Look for descriptions of your breast tissue.The signed breast density bill requires radiologists to amend radiology reports after characterizing a woman’s breast tissue as dense. The final report, sent to patients, must include the following notice: Your mammogram shows that your breast tissue is dense. Dense breast tissue is common and is not abnormal. However, dense breast tissue can make it harder to evaluate the results of your mammogram and may also be associated with an increased risk of breast cancer. This information about the results of your mammogram is given to you to raise your awareness and to inform your conversations with your doctor. Together, you can decide which screening options are right for you. A report of your results was sent to your physician.
