Tamoxifen appears to reduce the risk of benign breast disease and may result in fewer biopsies, according to an analysis of data from a major randomized clinical trial of tamoxifen. The findings appear in the February 19 issue of the Journal of the National Cancer Institute.
Tamoxifen was shown in the Breast Cancer Prevention Trial to reduce the incidence of invasive and noninvasive breast cancer by as much as 50% compared to placebo. Other studies have suggested that tamoxifen can also decrease the size of benign breast lesions, which have been associated with a modest increase in the risk for developing invasive breast cancer.
To examine the effect of tamoxifen on the risk of developing benign breast lesions, Elizabeth Tan-Chiu, M.D., of the Cancer Research Network in Plantation, Fla., and her coworkers from the National Surgical Adjuvant Breast and Bowel Project examined the incidence of benign breast disease among 13,203 women treated with either tamoxifen or a placebo as part of the Breast Cancer Prevention Trial. The authors also noted how many biopsies each group of women underwent.

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
