Karagas Data Cited in Bladder Cancer Study
November 19, 2009
Using data from Dartmouth epidemiologist Margaret Karagas's studies of possible triggers of cancer among northern New England residents, researchers from the National Cancer Institute (NCI) found an increased risk of bladder cancer for chronic, long-term smokers of cigarettes in the region since the mid-1990s.
The findings of the NCI study, which appear online in the November issue of the Journal of the National Cancer Institute, show the risk of bladder cancer growing, among current smokers in New Hampshire, to five times the risk for non-smokers studied in the Granite State between 2001 and 2004. Researchers also found that among individuals who smoked the same number of cigarettes over their lifetime, smoking fewer cigarettes per day for more years may cause more harm than smoking more cigarettes per day for fewer years.
DMS colleagues working with Karagas were Alan R. Schned, MD, a member of the Cancer Center's Prostate and Genitourinary Cancer Programs Team; Angeline S. Andrew, PhD, a member of the Cancer Center's Cancer Epidemiology and Chemoprevention Program; and Richard Waddell, DSc, research assistant professor of medicine.
