The findings suggest that aspirin's anti-inflammatory effects may help protect against this type of skin cancer. The study is published early online in CANCER, a peer-reviewed journal of the American Cancer Society.
In the Women's Health Initiative, researchers observed US women aged 50 to 79 years for an average of 12 years and noted which individuals developed cancer. At the beginning of the study, the women were asked which medications they took, what they ate, and what activities they performed.
When Jean Tang MD, PhD, of Stanford University School of Medicine in Palo Alto, and her colleagues analyzed available data from 59,806 Caucasian women in the study, they found that women who took more aspirin were less likely to develop melanoma skin cancer during the 12 years of follow up. Overall, women who used aspirin had a 21 percent lower risk of melanoma relative to non-users. Each incremental increase in duration of aspirin use (less than one year of use, one to four years of use, and five or more years of use) was associated with an 11 percent lower risk of melanoma. Thus, women who used aspirin for five or more years had a 30 percent lower melanoma risk than women who did not use aspirin. The researchers controlled for differences in pigmentation, tanning practices, sunscreen use, and other factors that may affect skin cancer risk.
"Aspirin works by reducing inflammation and this may be why using aspirin may lower your risk of developing melanoma," said Dr. Tang. Other pain medications, such as acetaminophen, did not lower women's melanoma risk. Dr. Tang noted that the findings support the design of a clinical trial to directly test whether aspirin can be taken to prevent melanoma.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
