Screening among women between 40 and 50 tied to lower mastectomy risk after breast cancer

Wednesday, December 1, 2010 (Last Updated: 12/02/2010)

WEDNESDAY, Dec. 1 (HealthDay News) -- Women between the ages of 40 and 50 who undergo a yearly mammogram appear to have a lower risk of mastectomy following breast cancer, according to a study presented at the annual meeting of the Radiological Society of North America, held from Nov. 28 to Dec. 3 in Chicago.

Nicholas M. Perry, M.D., of The Princess Grace Hospital in London, and colleagues identified 971 women who had been diagnosed with breast cancer between 2003 and 2009. At diagnosis, 393 (40 percent) were under the age of 50, including 156 women between the ages of 40 and 50 who had full clinical data available. The investigators compared the number of women receiving mastectomy versus breast-conserving surgery by history of prior mammography and age.

Of the 156 treated women, the investigators found that 114 (73 percent) had no prior mammograms. Forty-two women (27 percent) had undergone mammography, including 29 women (19 percent) who had been screened with at least one mammography within the previous two years. Sixteen women (10 percent) underwent a mammogram one year previously. The investigators also found that mastectomy was the required treatment for three of 16 women (19 percent) with a prior mammogram at one year, compared to 64 of 140 women (46 percent) who had not had a mammogram in the previous year.

"The results of this study support the importance of regular screening in the 40 to 50 age group," Perry said in a statement. "Women in this age group who had undergone mammography the previous year had a mastectomy rate of less than half that of the others."
