Jenna Fischer is more than just Pam Beesly from “The Office.” The Emmy-nominated actor and mother of two is also a cancer survivor. Fischer got candid about her health on Tuesday, revealing on Instagram that she had been battling breast cancer since late 2023.

“I am cancer free,” the “Office Ladies” podcast co-host said in an emotional post that showed off her “patchy pixie” hairstyle and detailed her cancer journey. “I will continue to be treated and monitored to help me stay that way,” she continued. Fischer, 50, said her cancer battle began in October 2023 when she went in for her annual mammogram .

She said she received “inconclusive results” to due her dense breast tissue and underwent a breast ultrasound as a result. “They found something in my left breast,” Fischer said. In December 2023, doctors conducted a biopsy on the lump and diagnosed the actor with Stage 1 triple-positive breast cancer.

The cancer is “aggressive,” Fischer said, but also highly responsive to medication and treatment. When the new year came around, she had a lumpectomy to remove the tumor. She also needed both chemotherapy and radiation to ensure the cancer did not return.

Fischer said she underwent 12 rounds of chemotherapy starting in February and three weeks of radiation beginning in June. Months later, the actor says she remains vigilant. “I’m happy to say I’m feeling great,” Fischer added.
