New breast cancer screening poses radiation risks

More reports will be published in the National Breast Cancer Awareness to help men and women better understand the risk of breast cancer and how to prevent the disease, which is diagnosed in more than 175,000 women and kills about 50,000 each year in the United States.

Be aware of radiation-induced breast cancer risk, foodconsumer.org – Pink News, 12 Oct 10, In October – the National Breast Cancer Awareness Month, women are encouraged to receive annual breast cancer screening. Many women may not be aware though that mammography screening by itself can cause breast cancer. The radiation induced breast cancer risk is particularly higher from the newly approved screening instruments.
The U.S. Food and Drug Administration has reportedly approved two new screening methods – breast-specific gamma imaging (BSGI) and positron emission mammography (PEM), which University of Colorado-Denver professor Dr. Edward Hendrick said need more research to ascertain its efficacy and safety.

Dr. Hendrick reported online Aug 24, 2010 in Radiology that both BSGI and PEM are linked with much higher breast cancer risk per screening than the risks associated with the mammography currently used and the cancer risk from the new methods is also found in other radiosensitive organs.

The breast cancer screening used today has already been known to boost breast cancer risk.

Dr. Samuel S. Epstein, professor emeritus of Environmental and Occupational Medicine at the University of Illinois  School of Public Health says on his website preventcancer.com postmenopausal women who undergo annual screening for a ten-year period would receive exposure to about 10 rads of radiation for each breast.

According to Dr. Epstein, each rad results in one cancer case in every 100 premenstrual women. A woman with exposure to 10 rads or receiving 10 screenings in 10 years would have a 10 percent risk of developing breast cancer, or 10 percent of women would develop the disease…….

Unlike mammography currently used, which mostly only affects breasts, BSGI and PEM irradiate all body organs, which means that the radiation employed in the new screening instruments will raise cancer risk in other organs.

Dr. Hendrick concluded “The results indicate that BSGI and PEM are not good candidate procedures for breast cancer screening because of the associated higher risks for cancer induction per study compared with the risks associated with existing modalities such as mammography, breast ultrasound and breast MRI.”

More reports will be published in the National Breast Cancer Awareness to help men and women better understand the risk of breast cancer and how to prevent the disease, which is diagnosed in more than 175,000 women and kills about 50,000 each year in the United States.

Stay tuned.
