Breast Cancer Detection Rates May Vary

(Ivanhoe Newswire)  – The Prevention and Cancer Control at Cancer Care Ontario in Toronto, Canada has found that digital direct radiography (DR) is significantly more effective than computed radiography (CR) at detecting breast cancer.

The findings are the first to show a difference between the two types of digital imaging when compared with screen film mammography. For the study, a total of 403,688 women were screened by screen film mammography, while 220,520 had DR and 64,210 underwent CR. The women were followed for 12 months after screening.

DR detected 4.9 cancers per 1,000 mammograms, a figure almost identical to screen film mammography's rate of 4.8 cancers per 1,000 mammograms. However, CR's detection rate of 3.4 cancers per 1,000 mammograms was significantly lower. "CR was 21 percent less effective than DR," Anna M. Chiarelli, Ph.D., senior scientist in Prevention and Cancer Control at Cancer Care, was quoted as saying.  "This could result in about 10 fewer cancers detected per 10,000 women screened."
