Is breast cancer being over-diagnosed?

February 6th, 2013

There is no question that the advent and spread of mammograms led to an increase in early detection of breast cancer, and that early detection and diagnosis of cancer has been proven to result in better treatment outcomes and longer survival times.

However, when reviewing statistical information for breast cancer something about the numbers doesn’t quite add up.

According to research published in the November 22, 2012 issue of The New England Journal of Medicine, screening mammography correlated with a doubling of cases of early-stage breast cancer detected each year (from 112 to 234 cases per 100,000 women). At the same time there was only an 8 percent decrease in the rate at which women are diagnosed with late-stage cancer (from 102 to 94 cases per 100,000 women).

There are only two ways to explain these numbers: either the incidence of breast cancer is growing at an alarming rate – which does not appear to be the case – or many women who do not have cancer at all are told they have it.

Fructose and obesity

February 6th, 2013

There is no question that we have an obesity epidemic in our country. When wondering what could be the cause, it’s easy to conclude that people are just eating too much. While there is no question that portion size has something to do with this crisis, there must be other and more subtle factors at play that prevent people from knowing when they’ve had too much to eat.

According to recent research, one such factor could be fructose, increasingly used as a sweetener for drinks.

In this study researchers used MRI scans to track blood flow to different parts of the brain.

What they found is that, when people had a drink sweetened with fructose or high-fructose corn syrup containing 55% fructose, areas of the brain that have to do with feeling like we’ve had enough to eat were not getting stimulated like they were when regular sugar was used.

I am not saying this to promote the use of sugar which

However, when looking at studies like this one – and others like it – it becomes very clear that fructose presents problems for health and weight regulation that go beyond those of regular sugar or glucose.
