Fewer Americans trying to lose weight; what that means for cancer prevention

By Posted on Leave a comment on Fewer Americans trying to lose weight; what that means for cancer prevention

According to a recent study, fewer US adults with overweight or obesity are trying to lose weight in what is a concerning trend for cancer prevention. With obesity rates increasing and fewer at a healthy weight, more people will be at risk for several cancers such as post menopausal breast and colorectal, as well as other chronic diseases like type 2 diabetes.

In their analysis, researchers used data from NHANES (National Health and Nutrition Examination Survey) from 1988 through 2014 to compare weight loss efforts over the past couple of decades. They found that the percent of Americans with overweight trying to lose weight dropped from 56% to 49% in the past 25 years. This drop occurred in nearly all gender and ethnic categories, but perhaps the most concerning decline was for black women. Almost 8 in 10 black women have overweight or obesity, but those trying to lose weight went from 65.5% to almost 55%. White women and men also showed drops in weight loss efforts.

For cancer prevention, maintaining a healthy weight throughout life is one of the most powerful lifestyle factors for lower risk. In those who already have overweight or obesity, we don’t know if losing weight will lower risk, though it seems to make sense. But we do know that losing weight will reduce risk of type 2 diabetes, a risk factor for some cancers, and it can reduce chronic inflammation and other markers for cancer risk.

    Advanced Prostate Cancers Rise, Reducing Your Risk

    By Posted on Leave a comment on Advanced Prostate Cancers Rise, Reducing Your Risk

    While US prostate cancer rates overall have stayed about the same over a decade, cases of the advanced and most deadly types of prostate cancers have steadily grown, finds a new study that highlights the need to focus on prevention. The study was published in Prostate Cancer and Prostatic Diseases.

    AICR’s recent report on prostate cancer found that being overweight or obese increases men’s risk for advanced cancers.

    Yesterday’s study found that new cases of men diagnosed with metastatic prostate cancer rose 72 percent from 2004 to 2013. Metastatic cancers means they have spread beyond the prostate (or other site). These advanced cancers are often aggressive and deadly.

      4 of every 10 women in US, 17% of kids now obese – disturbing news for cancer prevention

      Four of every ten women living in the US are now obese, a new high in the obesity epidemic, with rates continuing to be disturbingly high among children, finds two new studies published in JAMA.

      The findings by scientists at the Centers for Disease Control are significant for cancer risk and obesity prevention efforts.

      Aside from not smoking, obesity is the single largest lifestyle factor linked with increased cancer risk. Too much body fat now links to higher risk of 11 cancers, including post-menopausal breast, colorectal, and ovarian.

      Screen Shot 2016-06-08 at 12.59.06 PMThe study that focused on adults found that in 2014, almost 38 percent of people living in the US were obese overall. That rate is slightly lower for men, with 35 percent obese, and higher for women, at 40.4 percent of women categorized as obese.
