Method shows promise for early detection of pancreatic cancer

Optical technology developed by a Northwestern University biomedical engineer shown to be effective in the early detection of colon cancer now appears promising for detecting pancreatic cancer, the fourth most common cause of cancer deaths in the United States.
Known as a silent killer, with no method of early detection, pancreatic cancer spreads rapidly and seldom is detected in its early stages. The new technique could lead to the first screening method for pancreatic cancer in asymptomatic patients, said Vadim Backman, developer of the technology and professor of biomedical engineering at Northwestern’s Robert R. McCormick School of Engineering and Applied Science.
Sex differences found in COPD

In the first study to directly compare men and women with chronic obstructive pulmonary disease, or COPD, and severe emphysema, researchers have found that there are marked differences between the sexes.
The study, led by Fernando J. Martinez, M.D., of the University of Michigan, was reported in the August 1, 2007 issue of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.
Worldwide Distribution of Cervical Cancer Virus is Consistent with Vaccine Targets

The variety of human papilloma viruses that cause invasive cervical cancer cases worldwide are largely consistent across continents, according to a new study from the University of North Carolina at Chapel Hill.
This finding means that prophylactic vaccines currently available against these two most prevalent types of human papillomavirus (HPV) – which can cause cervical cancer – could prevent about 70 percent of invasive cervical cancer (ICC) cases around the world, the researchers found.
