“We at the American Institute for Cancer Research (AICR) welcome this report, which echoes AICR’s advice to focus on factors that have been clearly and convincingly shown to lower breast cancer risk — factors like eating smart, staying lean, moving more — and, of course, avoiding tobacco,” said AICR’s Director of Research, Susan Higginbotham, PhD, RD. “We know that many people are worried about other factors like air pollution, cosmetics, cleaning products and plastic food containers, but as the IOM report shows, we do not have solid scientific evidence that these factors affect human cancer risk. More research is needed.” Read more… “New IOM Report on Environmental Links to Breast Cancer”
In September 2010, AICR published “The Diabetes-Cancer Connection” paper discussing the research on the link between these two diseases and how health professionals can counsel patients on lifestyle changes to lower risk of both.
Now several studies in the Journal of Clinical Oncology show how both type 2 diabetes and insulin resistance negatively impact prognosis in breast cancer patients. Those with type 2 diabetes or insulin resistance do not fare as well as breast cancer patients who did not have those conditions.
An accompanying editorial discusses two simple procedures that health care providers should do for patients with breast cancer to improve outcomes.
1. Measure waist circumference. This simple measure may point to metabolic syndrome associated with type 2 diabetes and related risk factors.
2. Measure HOMA index (indicator of insulin resistance).
The authors of the editorial explain that with these measures, health care providers would be able to individualize a patient’s treatment to include diet and physical activity programs that are known to improve survival for many.
The editors give a call to action to integrate care of these two diseases:
“The time has come to overcome the conventional tunnel vision that results in two diseases being treated by separate clinicians, and to move towards a comprehensive approach that ideally integrates oncologists, internists, nutritionists, and other health care professionals in an attempt to improve breast cancer prognosis in a significant proportion of patients.” Read more… “The Diabetes-Cancer Connection: Breast Cancer”
Dr. Welsh chaired our 2010 research conference and its plenary session on aging, diet, physical activity and cancer, but she also presented on her own research involving vitamin D and breast cancer.
Dr. Welsh reviews her presentation, and shares some of the implications of her cutting-edge, AICR-supported research.
Here’s a handy glossary to some of the terms she uses with which you might be unfamiliar:
“…knockout of the vdr…”: Here, she’s talking about working w/an organism whose breast cells don’t respond to the presence of vitamin D, and tracking how this affects the way its breast tissue responds. Her work suggests that vitamin D plays an important role in governing the breast’s immune response.
“…cytokines...”: These are the cellular message-carriers of our immune system — they help our bodies defend against infections by passing along information and regulating our immune response.
“…the neonate…”: The newborn.
We fund cutting-edge research and give people practical tools and information to help them prevent–and survive–cancer.
