ROCHESTER, Minn — Senator Amy Klobuchar has been pronounced cancer-free after her latest sixth-month check at Mayo Clinic. The diagnosis was a special relief for Klobuchar as she begins a campaign for re-election to the U.S. Senate. Klobuchar, age 64, is seeking a third six-year term. She was diagnosed with Stage 1A breast cancer in early 2021 and began therapy. Doctors removed small calcification in a minimally invasive procedure. In her latest check-up, she was given an all-clear. Even so, Klobuchar said, she will undergo a couple days of radiation as a precaution.
