Us Weekly reported on November 15, 2026, that Chicago Fire actress Robyn Coffin has been diagnosed with breast cancer and is preparing for surgery.

Us Weekly reported on November 15, 2026, that Chicago Fire actress Robyn Coffin has been diagnosed with breast cancer, citing a statement on a GoFundMe page organized by her friend Gianine DeFrancesco. The fundraiser, with an initial goal of $75,000, had raised more than $15,000 at the time of publication. Coffin is expected to meet her care team on November 24 to decide between a right partial mastectomy with magseed localization, currently scheduled for December 3 and followed by radiation, or a full mastectomy.

DeFrancesco said that if the partial procedure is confirmed, Coffin expects to be out of work for three weeks; a full mastectomy would mean a longer recovery given the more extensive surgery. Insurance is expected to cover much of an estimated $40,000 in surgery and hospital costs, with the fundraiser meant to cover lost income and other gaps, including a longer recovery or medication not fully covered. Coffin's husband, Grant, and friends were described as her caregivers during recovery.

Coffin, who has appeared in more than 60 episodes of Chicago Fire as Cindy Herrmann, previously played a storyline in which her character was diagnosed with lung cancer and treated with chemotherapy and radiation before being declared cancer-free. Costars Miranda Rae Mayo and Hanako Greensmith shared the fundraiser and personally donated, according to Us Weekly.

The report does not specify Coffin's cancer stage, tumor type or full treatment timeline beyond the planned surgery and radiation, and her final surgical plan awaits her November 24 appointment.

Dr. Axe’s Take

Facing a choice between partial and full mastectomy before imaging and surgical planning are finished is one of the hardest waiting periods in cancer care, and it drains patients and families even before treatment starts. I'd tell anyone in Coffin's position to lean hard on caregivers, since recovery from either surgery draws down the body's resources fast. For readers watching someone they love go through this, the most useful thing you can do is handle meals, rides and bills so the patient can focus on healing. I wish Robyn Coffin a smooth surgery and full recovery.
