Jenna Fischer, who played Pam Beesly in the US Office, has revealed she was diagnosed with an “aggressive” breast cancer in December last year.

The 50-year-old shared a photo of herself in her “patchy pixie” haircut to mark breast cancer awareness month.

“After completing surgery, chemotherapy and radiation I am now cancer free,” she wrote on Instagram.

Fischer said problems were flagged during a routine mammogram, where inconclusive results due to dense tissue led her doctor to order an ultrasound.

“They found something in my left breast,” she said. “A biopsy was ordered. Then, on December 1, 2023, I learned I had Stage 1 Triple Positive Breast Cancer.”

The actress noted the cancer is “aggressive… but highly responsive to treatment,” and said she underwent a lumpectomy.

“Luckily my cancer was caught early and it hadn’t spread,” Fischer said, before adding she had 12 rounds of weekly chemotherapy from February and had three weeks of radiation treatment in June.

“While I continue to be treated with infusions of Herceptin and a daily dose of Tamoxifen, I’m happy to say I’m feeling great.”

She urged her followers to get their annual mammograms, adding: “My tumour was so small it could not be felt on a physical exam.

“If I had waited six months longer, things could have been much worse. It could have spread… Consider this your kick in the butt to get it done.”
