Use of tamoxifen by high risk women is low due to both failure of doctors to offer it and patients refusal to accept it, according to the results of a new study led by researchers at Northwestern Memorial Hospital. While tamoxifen chemoprevention has been shown to reduce the occurrence of breast cancer by nearly 50 percent in women with elevated risk, this study shows that the drugs risks and benefits arent always appropriately evaluated when determining who should take it.
The study, which will be published March 22, 2004 in the online edition of CANCER, is the largest to date to review use of the drug in risk-eligible women.
"The study shows that doctors tend to offer tamoxifen to women who will reap the greatest benefit from the drug due to risk caused by certain types of benign breast disease and to those at lower risk of severe side effects. That makes sense," explains Monica Morrow, M.D., the studys lead author and director of breast surgery at Northwestern Memorial Hospital. "What doesnt make sense is that women significantly less likely to have side effects, such as premenopausal women and those without a uterus, did not accept tamoxifen more frequently than other groups." Dr. Morrow is also a professor of surgery at Northwestern Universitys Feinberg School of Medicine.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
