Early Detection of Breast Cancer Backed by U.K. Study

Monday, December 7, 2015

According to a study of 5.2 million U.K. women published in the journal Lancet Oncology, detecting and treating ductal carcinoma in situ (DCIS) lowers the number of invasive breast cancers found over the next three years. For every three cases of DCIS detected and treated, one fewer case of invasive cancer was diagnosed in the following three years than would have been without early intervention, the study found. The study was led by SBI member and Honorary Fellow, Stephen Duffy, MD. 

SBI response to U.K. study that found DCIS detected by screening suggests that detection and treatment of DCIS is worthwhile in prevention of future invasive disease

"Mammography screening began in the mid 1980's and soon after, for the first time in 50 years, the death rate from breast cancer began to fall.  As more and more women have participated in screening the death rate has now declined so that there are 36% fewer women dying each year than would have died had screening and improvements in therapy not been available.  The importance of early detection is seen in a study at two of the major Harvard Teaching hospitals where more than 70% of women who died from breast cancer, despite access to the latest therapies, were among the 20% of women who are not participating in screening.  There are no good national statistics on mammography and breast cancer deaths, but the Harvard study suggests that many of the 40,000 deaths from breast cancer that still occur each year are due to women not participating in screening.

False Positive Mammograms May Be A Risk Factor For Breast Cancer

Saturday, December 5, 2015

NBC Nightly News (12/5, story 8, 2:10, Welker) reported, in continuing coverage, that a new study found that false positive mammograms may be a new warning sign for breast cancer that some doctors now “say should...be added to the list of risk factors for the disease.” 

Physicians Look To Ease Anxiety When Giving Mammogram Results

Friday, October 16, 2015
The NPR (10/16, Hobson) “Shots” blog reports that studies have found “about 61 percent of women will have at least one false positive result,” on their mammograms and these “false positives are associated with anxiety.” A study published in the Journal of the National Cancer Institute looked into interventions to attempt to reduce the worry and stress caused by false positive mammograms, such as immediately reading the results and providing educational materials. Debra Monticciolo, chairwoman of the American College of Radiology’s Commission on Breast Imaging says that assessing a mammogram is different then other types of X-rays because “every breast looks different. It’s like reading fingerprints. There isn’t just one normal.”

Treatment Changes For DCIS Have Not Had An Impact On Breast Cancer Survival Rates, Study Indicates

Wednesday, October 14, 2015
The NPR (10/14, Shute) “Shots” blog reports that research suggests that “shifts in treatment since 1999 away from single mastectomy and toward lumpectomy with radiation for DCIS haven’t changed breast cancer survival rates, according to a study that looked at data on over 120,000 women.” The research was published online in the Journal of the National Cancer Institute.
