Less Radiation from Digital Mammography Than Conventional Mammography

Statistics taken from one of the largest mammography trials in history shows that overall the radiation dose connected with digital mammography is markedly lower than conventional mammography.

Statistics taken from one of the largest mammography trials in history shows that overall the radiation dose connected with digital mammography is markedly lower than conventional mammography(averaging 22 percent lower).

The reduction could be greater in women with larger and denser breasts, according to a study published in the February issue of the American Journal of Roentgenology.

Breast cancer is a cancer that affects the breasts or mammary glands. Early detection and lifestyle changes help in controlling breast cancer.

"The ability to reduce the radiation dose for many women is another step forward for breast cancer screening with mammography — which saves thousands of lives each year," said R. Edward Hendrick, PhD, lead author of the study.

The American College of Radiology Imaging Network (ACRIN) Digital Mammographic Imaging Screening Trial (DMIST) published in 2005, enrolled 49,528 women and found that digital mammography detected significantly (up to 28 percent) more cancers than film mammography in women younger than 50 years of age, premenopausal and preimenopausal women, and women with dense breasts.

In this latest DMIST study, published in AJR, technical data from 5,102 DMIST participants were evaluated, demonstrating that the dose received by women imaged with digital mammography was significantly lower than that received by the same women imaged with standard film mammography.

About Cancer in Women
Cancer is one of the frequently talked about and most feared disease that falls under the genre of lifestyle diseases that have evolved, rather rapidly, in the past two decades.

"The average breast radiation dose per view was 2.37 mGy for film mammography and 1.86 mGy for digital (22 percent lower for digital than film mammography)," said Hendrick.

Digital mammography is similar to conventional except with digital, X-ray images are collected on a digital detector and stored on a computer rather than being collected and stored on film. "While the radiation dose from both film and digital mammography are low, further dose reduction is an added benefit of digital mammography over and above its ability to better detect cancers in women with dense breasts," said Hendrick.

Breast Lumps
Most breast lumps are caused by hormonal changes in a woman and may not be cancerous. Common causes of breast lumps include fibroadenosis, breast cancer, breast cyst.

Access to digital mammography continues to increase. More than 60 percent of U.S. breast imaging facilities offer digital mammography and more are acquiring digital services each month. "As digital mammography has now been shown to significantly lower the radiation dose, it is likely that access to it will continue to grow," said Hendrick.
