A new study from American Cancer Society researchers finds use of 30 tablets a month or more of acetaminophen for five or more years was associated with an estimated 38% lower risk of prostate cancer.
The study appears in Cancer Epidemiology, Biomarkers and Prevention and is one of only two studies of prostate cancer to date that have examined the association with acetaminophen use that was both long-term and regular.
Use of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), particularly long-term use, has been associated with modestly reduced risk of prostate cancer in some previous epidemiologic studies. Acetaminophen, a commonly used pain-reliever, is not traditionally considered an NSAID but can have anti-inflammatory effects.
For the current study, researchers led by Eric Jacobs, Ph.D., American Cancer Society epidemiologist, examined the association between acetaminophen use and prostate cancer incidence among 78,485 men in the Cancer Prevention Study II Nutrition Cohort. Information on acetaminophen use was obtained from a questionnaire completed at study enrollment in 1992 and updated using follow-up questionnaires in 1997 and every two years thereafter.During follow-up from 1992 through 2007, there were 8,092 incident prostate cancer cases identified. Current regular use of acetaminophen (> 30 pills per month) for 5 years or more was associated with lower risk of overall prostate cancer (RR = 0.62, 95% CI 0.44-0.87) as well as lower risk of aggressive prostate cancer (RR = 0.49, 95% CI 0.27-0.88). Current regular use of
"While the results of this observational study suggest that long-term regular acetaminophen use may be associated with lower prostate cancer risk, our findings require replication by other studies, and do not justify use of acetaminophen to prevent prostate cancer. Acetaminophen is considered relatively safe when used at recommended doses but unintentional acetaminophen overdose is an important cause of acute liver failure." said Dr. Jacobs. "Still, results of this study could lead to further research on acetaminophen that might provide biological insights about the process of prostate cancer development and how this process could be slowed."

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
