Study shows long-term benefits of breast screening

28.06.2011
Results from the longest running breast screening trial show that screening with mammography reduces the number of deaths from breast cancer.

The study*, by researchers at Queen Mary, University of London, shows that the number of deaths that are prevented goes up year after year.

The results are new evidence of the long-term benefits of regular breast screening.

Senior author, Professor Stephen Duffy explained: "Breast cancer can take many years to develop so to tell if screening is effective, we need to see how women fair in the long-term.

"In this study, we've continued to monitor women for nearly three decades and we've found that the longer we look, the more lives are saved."

The study included over 130,000 women and was the first to show that screening, with mammography only, led to fewer deaths from breast cancer. It compared a group of women who were invited for regular mammograms with a group who were not. The women have now been followed up for 29 years to see how many died of the disease.

The results showed that 30 per cent fewer women in the screening group died of breast cancer and that this effect persisted year after year.

The study also showed that one cancer death is prevented for approximately every 400 to 500 women in the screening group.

Professor Duffy added: "This suggests that the long-term benefits of screening, in terms of deaths prevented, are more than double those often quoted for short-term follow-up.

"Unfortunately, we cannot know for certain who will and who won't develop breast cancer. But if you take part in screening and you are diagnosed with breast cancer at an early stage, the chances that it will be successfully treated are very good."

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
