Connecticut has seen significant reductions in deaths from breast and colon cancer in the last three decades, but the state exceeds the national mortality rate for uterine cancer and three other cancers, as well as for mental health and substance use disorders. An analysis of data compiled by the Institute for Health Metrics and Evaluation at the University of Washington, published in JAMA, also shows wide disparities between Connecticut counties in death rates from certain cancers and other illnesses. Windham County had the highest mortality rates for seven of 10 cancers identified in the study as having the highest disease burden or responsiveness to screening and treatment, including pancreatic, uterine and lung cancer. Tolland County, meanwhile, had the lowest death rates for five cancers, including breast cancer, while Fairfield County was lowest for four. Similarly, deaths from chronic respiratory diseases in Windham County were nearly double the rate in Fairfield County – 63.13 per 100,000, compared to 34.15.
