Many online cancer tests inadequate

31.10.2006
Many self-tests for cancer available on the Internet do not fulfil the EU’s quality criteria, according to a new doctoral thesis from Karolinska Institutet.

“It is important to enlighten people searching for health information on the net that some sites don’t come up to scratch,” says MD Alexandra Ekman.

More and more people are starting to use the Internet to obtain health information. On certain websites, visitors can test themselves to find out what risk they run of developing a certain type of cancer. Alexandra Ekman examined a selection of such sites in 2001, 2002 and 2005, and her results show that none of them met all the quality criteria issued by the EU.

“Most sites are American, but all are available worldwide,” says Dr Ekman. “The information we found didn’t score particularly high on the quality scales we used. What’s more, there is no international consensus for quality criteria for the control and evaluation of information available online.”

However, Dr Ekman stresses that there are also sites that are fully adequate for assessing the risk of diseases. Her thesis started as an inventory in connection with a self-test for cancer that Karolinska Institutet launched a few years ago. The Swedish self-test was based on a site produced by the Harvard Centre for Cancer Prevention, which according to Dr Ekman maintains a high level of quality.

Her thesis also looks at the potential of the Internet in the new research field of

e-epidemiology. Information about diseases has traditionally been gathered through paper-based surveys, but there is much to suggest that web-based questionnaires give equally good results.

“Sweden is excellently suited for this kind of research because of our different population–based registries and our widespread use of internet, which reaches almost 100 per cent in some age-groups,” she says.

Epidemiology is the study of how diseases are spread throughout populations, and how risk and health factors interact with them. Researchers conducting such a study often monitor a large group of people over time to find out, for example, how their lifestyle affects their chances of developing a certain disease.

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...
