 For NPR News in the Twin Cities, I'm Emily Reese. Minnesota U.S. Senator Amy Klobuchar says she will undergo a few days of precautionary radiation treatment this month. That's after an outpatient procedure last month to remove a small spot called a calcification that was found during a routine exam. Klobuchar was treated for breast cancer in 2021. In a statement today, Klobuchar says doctors have declared her cancer-free.
