Summary
Despite the early diagnosis rate in South Dakota falling into the above average tier, the state still has a lot of work to do to make sure that more of those at high risk for lung cancer are screened.
South Dakota has improved access to expanded screening by covering it through its fee-for-service Medicaid program. The Lung Association encourages all states to cover lung cancer screening based on the latest guidelines across all fee-for-service and managed care plans without any financial or administrative barriers in their Medicaid programs.
South Dakota falls into the average tier for percent of patients receiving no treatment. Some patients do refuse treatment, but issues such as fatalism and stigma can prevent eligible patients from accessing treatment that may save or extend their lives. All patients should work with their doctors to establish a treatment plan and goals.
