Better mammography: A new and improved technology for reading mammograms called CAD (computer-aided detection) is described in the latest issue of The Economist . Researchers at Duke University Medical Center are developing a knowledge-based CAD system that compares the images taken by a radiologist with a large collection of normal and abnormal mammograms in a database. The new mammogram reading system has a lower rate of false positives than other systems.
Why cancer spreads: The great majority of cancer deaths—more than 90 percent of them—are caused when cancer cells begin to spread or metastasize from a primary tumor through the body to a vital organ such as the lungs, bones, brain or liver. Now, according to an illuminating article in the New York Times, scientists are beginning to understand more about metastasis and new therapies are beginning to accumulate. This is widely viewed by researchers as an important milestone in cancer treatment.

A study that examined the eating habits of 90,000 women over time found that there was an increased risk of breast cancer in those women who ate red meat. The risk of breast cancer was twice as high in the women who ate the most red meat compared to those who ate the least. This is a well-conducted study that comes out of the Harvard Nurses Health Study – a group of nurses who have volunteered to answer questions about their lifestyle over time that has given us insight into risk factors for various diseases. The study also suggested something called a “dose response” association – meaning that the more red meat a woman consumed, the greater her risk of breast cancer. These findings are not unexpected – similar studies have shown an increased risk of breast cancer as well as colon and prostate cancer – in people who eat red meat compared to non-meat eaters. Red meat also increases the risk for heart disease (coronary artery disease). Another line of evidence comes from Japan. In...
