The Office US star Jenna Fisher has revealed her breast cancer diagnosis

Actress Jenna Fisher has revealed that she has been undergoing treatment for breast cancer since December last year.

Best known for her role as receptionist Pam Beasley on the US version of The Office, Jenna said she is “now cancer free” after surgery and multiple rounds of chemotherapy and radiation treatment.

“I'm happy to say I'm feeling great,” Jenna shared on Instagram, adding that she's opening up about her treatment to encourage other people to check for symptoms of the disease.

“If I had waited six months, things could have been worse,” he wrote.

Jenna, who also hosts the Office Ladies podcast, played Pam in the mockumentary series between 2005 and 2013 alongside Steve Carell, who plays regional manager Michael Scott.

The widely-remembered series, based on a BBC series of the same name written and starring Ricky Gervais, is one of the most-watched shows on Netflix and has repeatedly ranked among the most popular US sitcoms.

Jenna said her cancer was discovered in October 2023 after a routine scan that she said she was putting off.

“Seeing women posting pictures of mammogram appointments on Instagram made me set up my own (which I was overdue for),” He wrote.

After that appointment, she said further tests revealed she had “stage 1 triple positive breast cancer.”

Jenna said that “luckily” her cancer was caught early but the tumor was aggressive so multiple rounds of treatment were needed.

There are several types of breast cancer and some, such as triple positive, are known as hormone receptor-positive cancers.

This means that tumors are encouraged to grow by hormones, such as oestrogen, progesterone and a protein called HER2, which are found naturally in the body.

These cancers are more likely to respond to drug treatments that target these hormones to help cancer cells stop dividing and growing.

According to the NHS breast cancer is the most common type of cancer affecting women in the UK, but it can also affect men.

More than 50,000 people in the UK are diagnosed with it each year and Statistics from cancer research It suggests that one in seven women in the country will be diagnosed in their lifetime.

It still claims more than 11,000 British lives each year, but cancer research says survival rates are improving, with 76% of patients surviving at least 10 years after diagnosis.

During chemotherapy, Jenna said she lost her hair and shared a photo on Instagram of her “patchy pixie” cut when it grew back.

She said she was ready to examine the “wigs” she had been wearing for the past year, adding that “a lot of people” in her life didn't know she was undergoing treatment.

“I need space and people who don't treat me like a cancer patient.”

But she highlighted the support she's received from people in the know, including her co-star Angela Kinsey, who plays picky security officer Angela Martin in the series and co-hosts the Office Ladies podcast.

“When I lost my hair, she wore the hat to our work meetings to make sure I wasn't alone,” Jenna said.

Jenna told her followers that she would “continue to be treated and monitored”, and urged fans to: “Get women checked”.

“My tumor was so small it couldn't be felt on physical exam,” she wrote, adding that if she delayed her scan “it could have spread”.

“Should you be diagnosed with breast cancer,” she wrote, “there's a village waiting to take care of you.”
