Coffee consumption inversely associated with risk of most common form of skin cancer

02.07.2012
Increasing the number of cups of caffeinated coffee you drink could lower your risk of developing the most common form of skin cancer, basal cell carcinoma, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.

"Our data indicate that the more caffeinated coffee you consume, the lower your risk of developing basal cell carcinoma," said Jiali Han, Ph.D., associate professor at Brigham and Women's Hospital, Harvard Medical School in Boston and Harvard School of Public Health.

"I would not recommend increasing your coffee intake based on these data alone," said Han. "However, our results add basal cell carcinoma to a list of conditions for which risk is decreased with increasing coffee consumption. This list includes conditions with serious negative health consequences such as type 2 diabetes and Parkinson's disease."

Basal cell carcinoma is the form of skin cancer most commonly diagnosed in the United States. Even though it is slow-growing, it causes considerable morbidity and places a burden on health care systems.

"Given the large number of newly diagnosed cases, daily dietary changes having any protective effect may have an impact on public health," said Han.

Han and his colleagues generated their results by conducting a prospective analysis of data from the Nurses' Health Study, a large and long-running study to aid in the investigation of factors influencing women's health, and the Health Professionals Follow-up Study, an analogous study for men.

Of the 112,897 participants included in the analyses, 22,786 developed basal cell carcinoma during the more than 20 years of follow-up in the two studies. An inverse association was observed between all coffee consumption and risk of basal cell carcinoma. Similarly, an inverse association was seen between intake of caffeine from all dietary sources (coffee, tea, cola and chocolate) and risk of basal cell carcinoma. However, consumption of decaffeinated coffee was not associated with a decreased risk of basal cell carcinoma.

"These results really suggest that it is the caffeine in coffee that is responsible for the decreased risk of basal cell carcinoma associated with increasing coffee consumption," said Han. "This would be consistent with published mouse data, which indicate caffeine can block skin tumor formation. However, more studies in different population cohorts and additional mechanistic studies will be needed before we can say this definitively."

In contrast to the findings for basal cell carcinoma, neither coffee consumption nor caffeine intake were inversely associated with the two other forms of skin cancer, squamous cell carcinoma and melanoma, the most deadly form of the disease.

Only 1,953 cases of squamous cell carcinoma and 741 cases of melanoma were recorded among the 112,897 participants included in Han's analyses.

"It is possible that these numbers are insufficient for any association with coffee consumption to be seen," said Han. "As the study participants are followed for a longer time, the number of cases of these conditions is likely to increase. We may be in a position in 10 years' time to better address this issue."

About the AACR
Founded in 1907, the American Association for Cancer Research (AACR) is the world's first and largest professional organization dedicated to advancing cancer research and its mission to prevent and cure cancer. AACR's membership includes 34,000 laboratory, translational and clinical researchers; population scientists; other health care professionals; and cancer advocates residing in more than 90 countries. The AACR marshals the full spectrum of expertise of the cancer community to accelerate progress in the prevention, biology, diagnosis and treatment of cancer by annually convening more than 20 conferences and educational workshops, the largest of which is the AACR Annual Meeting with more than 17,000 attendees. In addition, the AACR publishes seven peer-reviewed scientific journals and a magazine for cancer survivors, patients and their caregivers. The AACR funds meritorious research directly as well as in cooperation with numerous cancer organizations. As the Scientific Partner of Stand Up To Cancer, the AACR provides expert peer review, grants administration and scientific oversight of individual and team science grants in cancer research that have the potential for near-term patient benefit. The AACR actively communicates with legislators and policymakers about the value of cancer research and related biomedical science in saving lives from cancer.

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
