The Office star Jenna Fischer has revealed that she has undergone treatment for breast cancer.
Taking to Instagram to commemorate Breast Cancer Awareness Month, the 50-year-old reflected on her 2023 diagnosis, sharing that she had been diagnosed with Stage 1 triple positive breast cancer on December 1.
“Triple positive breast cancer is an aggressive form of breast cancer, but it is also highly responsive to treatment,” she wrote, adding that she underwent a lumpectomy in January 2024 to remove the tumour.
Although her cancer was caught and excised early, the actress revealed that “because of the aggressive nature of triple positive breast cancer, it still required chemotherapy and radiation to be sure it didn’t return.”
After 12 rounds of weekly chemotherapy, Fischer shared that she later underwent three weeks of radiation treatment, with her cancer now being managed with infusions and daily medication.

Alongside her reflection on her cancer journey, Fischer also shared that she is now cancer-free and hopes that her story offers support and awareness to those fighting breast cancer.
“Take it from Pam and her Pam Pams. Michael [Scott] was right. Get ’em checked ladies, and know that should you get a breast cancer diagnosis, there is a village waiting to care for you.”
The actress, best known for her portrayal of Pam Beesly in the iconic sitcom, further encouraged her followers to be diligent with their cancer screenings.
“Seeing women post photos of their mammogram appointments on Instagram needled me into setting my own {which I was late for). I’m so glad I did. Consider this your kick in the butt to get it done.”
“As anyone who has had a cancer diagnosis knows, your life changes immediately… Suddenly everything in your life is geared around one thing: fighting cancer,” she continued.

Now cancer-free, Fischer also shared her heartfelt thanks to her fellow The Office co-star Angela Kinsey, who “protected me and advocated for me.”
“For a long time, she was the only person in my workspace who knew. When I lost my hair, she wore hats to our work meetings so I wouldn’t be the only one. When I needed a break, we took one.”
Sharing her support, Kinsey took to the comments to share her love for her best friend, writing, “I love you and I’m so glad you’re sharing. I got your back, always.”
