Mammogram FAQs: Part 3, Patient Safety

Should women be concerned about radiation dose during mammography?
No. The risk of harm from radiation is very small when compared to the benefits of early breast cancer detection. Mammography Quality Standards Act (MQSA) has established a maximum radiation dose limit that is considered to be safe. There have been improvements in mammography that deliver 50 times less radiation than they received 20 years ago, with the risk of long-term effects being almost zero.

What should women with breast implants do about screening mammograms?
Women with breast implants should continue to have mammograms. (A woman who had an implant following breast cancer surgery should ask her doctor whether a mammogram of the reconstructed breast is necessary). It is important to inform the facility about breast implants when scheduling a mammogram. The technician and radiologist must be experienced in x-raying patients with breast implants. Implants can hide some breast tissue, making it more difficult for the radiologist to detect an abnormality on the mammogram. If the technologist performing the procedure is aware a woman has breast implants, steps can be taken to make sure that as much breast tissue as possible can be seen on the mammogram.

If I change facilities or need a second opinion, do I need my mammograms?
Good question! The answer is yes, but be sure they are originals–not copies. By law, you are entitled to your original mammograms. A doctor needs to compare past mammograms with current ones to see if there have been any changes, and original mammograms are needed for this comparison. Ask your facility for your original mammograms and for a copy of the medical version of your report. You will probably be asked to fill out a form to release your medical records. You can ask the facility to send your records to another medical facility, to your doctor, or to you. Your facility may charge a fee for this service. If they do, the fee must not be more than the cost of providing this service to you.
