He study at Umeå University, which is published in the journal Cancer Research and Treatment, is the first to investigate how excess body fat and factors relating to insulin resistance, including blood sugar, insulin, and leptin influence the risk of different types of breast cancer. The research team discovered that being overweight and having high blood sugar reduced the risk of lower-risk tumours, but the risk for more aggressive forms of breast cancer increased.
The results were based on data from health screenings of women in Västerbotten County, Sweden, which consisted of 561 women who had been diagnosed with breast cancer several years after the health screening, and 561 women who were free of the disease and who acted as a control.
Tanja Stocks, doctoral candidate at the unit of Urology and Andrology at Umeå University, is the first author of the study. She believes that the connection can be due to that insulin resistance increases the risk for progression of the disease.
"Hopefully now this will lead to work on how things like body fat and blood sugar levels affect the type of tumour that develops, as well as a person's overall cancer risk," she said.
The research group behind the study, led by senior Pär Stattin at the unit of Urology and Andrology, Department of Surgical and Perioperative Sciences, Umeå University, found for approximately one year ago a corresponding correlation for prostate cancer. Men with insulin resistance had a lower risk for more treatable tumours but had an increased risk for aggressive cancer, a link that was confirmed in several studies.Additionally, the research group also has previously found that high blood sugar levels increase the overall risk for cancer, mostly among women. The study was titled "Prospective study of hyperglycaemia and cancer risk" and published in the American journal Diabetes Care, Vol. 30 Number 3 March 2007.
"The most significant conclusion is that one can likely reduce the risk for aggressive cancer by leading a healthy lifestyle to help prevent cardiovascular disease, for example through regular physical activity, weight management and eating in moderation," said Tanja Stocks.Reference:

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
