Breast Cancer: Advances in Detection and Treatment
By Joshua Stuhlfaut, MD
Q. What is the difference between digital mammography and film mammography?
Digital mammography uses special detectors to convert low-dose x-rays into electrical signals. The signals produce computer images similar to conventional mammograms. From the patient's point of view, a digital mammogram is essentially the same as a conventional mammogram. However, the images produced can be adjusted and magnified on the computer screen to highlight potential cancers. Digital mammography may detect cancers in younger women and women with dense breasts better than conventional mammography.
Q: When should you have a breast MRI?
Breast MRI is increasingly used in the evaluation of suspicious masses and abnormal mammograms. For most women, breast MRI is used when mammogram and ultrasound exams are inconclusive. Women with breast cancer may undergo breast MRI as part of treatment planning. Breast MRI also is useful for assessing the integrity of breast implants.
The American Cancer Society now recommends screening with Breast MRI in addition to mammography for women who are at an extraordinarily high risk of developing breast cancer. Your physician can help you determine your overall risk and whether Breast MRI is an appropriate option for your breast screening.
Q: What is Breast MRI?
Breast MRI is a valuable tool for identifying breast cancer when other techniques do not provide enough detail. MRI scanners use a powerful but harmless magnetic field with special computer software to generate images of the body. This involves no x-rays or radiation. It is important to remember that breast MRI is not a substitute for screening mammography or breast ultrasound. Mammography may detect some cancers that are not evident on MRI.
Q: What is it like to have a Breast MRI?
MRI is painless. The average scan time is 30-45 minutes. Routine breast MRI exams require an injection of a contrast agent (via an IV). The contrast aids in detection of even the smallest cancers. You will be asked to lie down on your stomach on a cushioned bed. Your breasts will be positioned within a padded cutout on the bed. The bed will be moved into the MRI machine feet first. You will need to lie still the entire time. You will not feel anything, but you will most likely hear tapping or thumping as the machine works. After the exam, your radiologist will interpret the images and send the results directly to your physician.
