'Chicago Fire' actress Robyn Coffin diagnosed with breast cancer: What we know about her upcoming surgery

A familiar face from Chicago Fire is now facing a serious health challenge off screen. Robyn Coffin, who plays Cindy Herrmann on the NBC drama, was diagnosed with breast cancer. A fundraiser has also drawn donations from fans and members of the show’s cast as she prepares for surgery. The Chicago Fire actress has a pre-surgery appointment scheduled for November 24, according to her GoFundMe campaign.

How much has the GoFundMe raised?

The campaign titled “Standing with Robyn Through Surgery and Recovery” was organized by Gianine DeFrancesco and Robyn Coffin. It has raised $15,298 toward its $75,000 goal so far, from 165 donations, according to the campaign page. The money will help the Chicago Fire actress pay medical bills. It will also help cover lost income during her treatment and recovery.

The fundraiser says Robyn is scheduled to undergo a right partial mastectomy with magseed localization on December 3, 2026, with radiation expected to follow.

“If a full mastectomy is required, Robyn’s time off work will increase quite a bit, as the surgery is much more extensive,” the campaign states. “When Robyn doesn’t work, she doesn’t get paid,” the organizers wrote, adding that the campaign aims to provide financial support for a longer recovery, medication costs and other unexpected expenses.

The organizers closed their message with a note of gratitude to those supporting the actress: “So, Village; thank you in advance for embracing Robyn with love and support. We’ve got her!”

One of Coffin’s Chicago Fire co-stars, Miranda Rae Mayo, shared the GoFundMe in an Instagram Stories post. She also shared a message about her castmate. “This beautiful and wonderful woman is in need of support. You may know her as Cindy Herrmann on our show. Any and everything helps,” she wrote, adding a heart emoji.

Mayo, 36, also donated to the GoFundMe, along with Chicago Fire co-star Hanako Greensmith, according to PEOPLE.
