One of the co-stars of a popular TV sitcom just revealed a terrible health diagnosis she received nearly a year ago and has dealt with since then.

Actress Jenna Fischer, who played Pam in "The Office," announced on Tuesday that she was diagnosed last December with a particularly aggressive type of breast cancer, according to the Daily Caller.

Her prognosis is good, however, as Fischer also revealed that the cancer was caught early, the various treatments she's undergone and continues to receive have worked, and she is now cancer-free.

Diagnosed with breast cancer

In an Instagram post on Tuesday, Fischer wrote, "October is breast cancer awareness month. I never thought I’d be making an announcement like this but here we are."

"Last December, I was diagnosed with Stage 1 Triple Positive Breast Cancer," she continued. "After completing surgery, chemotherapy and radiation I am now cancer free."

Receiving the dreaded diagnosis

The post included several slides that contained a more thorough description of what Fischer had undergone, beginning with a routine mammogram in October 2023 that was inconclusive followed by a doctor-recommended ultrasound that led to a biopsy that resulted in her diagnosis of Stage 1 Triple Positive Breast Cancer.

That is a particularly "aggressive" form of breast cancer that is also "highly responsive to treatment," so she underwent a lumpectomy in January that succeeded in removing the small tumor before the cancer had spread to her lymph nodes or other parts of her body.

Still, because of how aggressive that form of cancer is, Fischer then endured 12 weeks of chemotherapy treatment beginning in February -- which led to hair loss and the use of hats and wigs -- followed by three weeks of radiation treatment in June, and though she was still taking hormonal drugs to ensure the cancer didn't return, she proclaimed that she was now "feeling great."

Sharing her journey to become cancer-free

Fischer shared that she'd decided to reveal all of this to help encourage other women to get checked out for cancer annually with a mammogram and to provide support for others who may have received a similar diagnosis and let them know that they are not alone.

She went on to note that such a diagnosis will change one's life completely and immediately, with fighting cancer becoming a singular focus, and how it takes a "village" of support to successfully wage that fight.

Her village was "amazing" and included not just doctors and nurses but also caregivers, other survivors, and her friends and family, some of whom were unaware of what she was going through but all of whom provided her with support in a variety of necessary ways.

Fischer gave a special thanks to her best friend, Angela Kinsey, who helped her continue working throughout the entire ordeal, and her husband Lee, who stood by her side and supported her through all of the treatments and appointments and everything else that comes with a grueling battle against cancer.

"I'm happy to say that I was recently re-screened, and the treatments worked. I am cancer free. I will continue to be treated and monitored to help me stay that way," she concluded and again reiterated the importance of getting a mammogram. "Get'em checked, ladies. And know that should you get a breast cancer diagnosis, there is a village waiting to care for you."
