Klobuchar said she later underwent surgery to remove the cancer and completed radiation treatment in May.
In August, it was determined that the treatment went well, Klobuchar said.
“Of course this has been scary at times, since cancer is the word all of us fear, but at this point my doctors believe that my chances of developing cancer again are no greater than the average person,” she said.
“Their support allowed me to continue my work with my colleagues on major pandemic and economic legislation, as well as chairing the joint Senate January 6th investigation and the For the People hearings while undergoing cancer treatment,” Klobuchar said.
Klobuchar used her announcement Thursday to urge Americans to not delay physicals and routine examinations because of the Covid-19 pandemic — as she had.
“It’s easy to put off health screenings, just like I did. But I hope my experience is a reminder for everyone of the value of routine health checkups, exams, and follow-through,” she wrote. “I am so fortunate to have caught the cancer at an early enough stage and to not need chemotherapy or other extensive treatments, which unfortunately is not the case for so many others.”
She added that the experience gave her time to reflect on her life and those she loves and also gave her “renewed purpose to my work.”
