Yet again we are reminded that bariatric surgery has quite an impressive record for improving the health of people with obesity. In a retrospective cohort study of 55,789 patients receiving bariatric surgery, risk of obesity-related cancer came down by half. Researchers matched the non-surgical control group using propensity scores for demographics, comorbidity, hormone therapy, and […]

“Bariatric surgery may be a powerful tool in breast cancer prevention and treatment,” write Trevor Crafts and colleagues in a new review paper for Obesity. But there’s just one problem. All of the research that points to this possible value is observational. So we need a prospective clinical trial of bariatric surgery to reduce the […]

Low-fat diets are back in the news this week. An impressive and important randomized, controlled clinical trial started way back in 1993 to test the possibility that a low-fat diet might reduce the risk of breast cancer in women after menopause. Needless to say, a lot has changed in 26 years since then. Back then, […]

Sometimes things are not what they seem. That’s a problem when something slips into scientific literature that’s not exactly true. We offer a prime example today. Here we have two papers where an RCT – a randomized controlled study – is not properly randomized. Apparently, the investigators, reviewers, and editors for these papers weren’t too fussy about […]

For some time now, the evidence has been pretty clear about obesity and breast cancer in older women. Obesity brings a 20-40% increase in breast cancer risk to women after menopause. But before menopause, the opposite is true. Now, new research provides a much clearer picture for younger women. A new study in JAMA Oncology […]

The close relationship between obesity and breast cancer is well known to researchers and oncologists. Obesity after menopause can raise the risk of breast cancer by 30-50%. Not only that, obesity makes the prognosis  worse – both before and after menopause. Survival rates drop significantly in women with abdominal obesity. The risk goes up with each […]
