No need for gene screens in breast cancer families

23.07.2008
Research reported today should provide relief to women who are worried after a relative’s breast cancer diagnosis.

The study in the open access journal BMC Cancer shows that a family history of breast cancer does not give a useful indication of the likelihood that a woman will develop it herself at an early age.

An increased risk of breast cancer for relatives of breast cancer patients has been demonstrated in many studies. As physicians and the general population have become more aware of this increased risk, the demand for referring healthy women with a family history of breast cancer for intensive screening or genetic testing has risen. Geertruida H. de Bock led a team from Leiden University Medical Centre in the Netherlands who investigated whether the increased risk was significant enough to accurately predict breast cancer.

According to de Bock, “Due to the low prevalence of early breast cancer in the population, the predictive value of a family history of breast cancer was 13% before the age of 70, 11% before the age of 50, and 1% before the age of 30.” These numbers are much lower than most women would probably expect. As the authors explain, “Applying family history related criteria results in the screening of many women who will not develop breast cancer at an early age.”

Given the psychological harm that screening visits can cause, more stringent criteria should be applied to early screening. The researchers recommend that these results be used to “reassure a large number of women regarding their personal breast cancer risk.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
