Postmenopausal women who are overweight — and especially obese — have a greater risk of developing breast cancers, finds a new study that highlights the importance of preventing weight gain, as it also raises questions about whether losing weight necessarily reduces that risk.
The study adds to a consistent body of research showing that overweight and obesity increases women’s risk of postmenopausal breast cancers. It was published yesterday in JAMA Oncology.
AICR estimates that a third of US breast cancers could be prevented if women were at a healthy weight throughout life, were active and did not drink alcohol.
In this study, as other research has seen, the heavier the women, the greater the risk. Women categorized as the most obese were at almost double the risk of the most common type of breast cancer, ER-positive, along with PR-positive tumors. These cancers are fueled by the hormones estrogen and progesterone, respectively.
The study used data from approximately 67,000 women who were all part of the Women’s Health Initiative trials. That study focused on preventing certain cancers, heart disease and osteoporosis. When the women entered the study in the mid 1990s they were 50 to 79 years old, and they were weighed. They also answered questions about their lifestyle habits, medical history and other health risk factors. After that, they were weighed annually and had regular mammograms. Continue reading
Every time you eat chocolate covered berries or drink a cup of tea, you are getting a dose of flavonoids! Flavonoids are compounds found in plant foods that are well studied for their role in preventing cancers, as well as other chronic diseases.
A new study on flavonoids is highlighted in Cancer Research Update. This study of Australian women looked at the role of flavonoids in preventing death from all causes, including cancer and heart disease specifically. Researchers found that women with the highest intake of flavonoids experienced 62% fewer deaths during the course of the 5 year study compared to those who consumed the least, with similar lower risk from cancer and hear disease.
Flavonoids are generally divided into 6 groups. Foods provide different flavonoids and so may have different health benefits.

The women in this study consumed most (about 80%) of their flavonoids from black tea, which contains flavanols. The women were not, however, eating many foods like Continue reading
With nearly 1 in 2 Americans developing cancer at some point in their lives, prevention must start early. So we’ve teamed up with AICR and are reaching out to parents and camps with our free printable activities, recipes and trackers to use during 6 weeks of summer! Kids’ activity level actually tends to decrease in the summer despite the images of going to the beach, riding bikes and playing outside. There is often less activity and more lounging, resulting in excess weight gain. This is why summer is an important time to focus on children’s health!
You can’t change your genes, but you can turn your protective shield on to influence them! Diet and lifestyle can make a huge difference to your health, while altering your genetic influences.
Think about what good health means to you and your family – living longer or better, social acceptance (for kids at school), having more energy, or for adults, being able to do daily chores with no problems, looking younger and/or setting an example for your kids. Then commit to just a few activities this summer that match your idea of good health.
Here are 7 ideas you can do — and why they’re so important — to help get you started: Continue reading
