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:

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
