Chicago Fire Star Diagnosed With Breast Cancer

Chicago Fire actress Robyn Coffin, who plays Cindy Herrmann, has been diagnosed with breast cancer and is preparing for surgery. She is scheduled for a right partial mastectomy on Dec. 3, 2026, followed by radiation, with doctors expected to confirm the plan at a Nov. 24 appointment. If the partial mastectomy proceeds, Coffin expects to miss about three weeks of work; a full mastectomy could mean a longer recovery. Coffin and fundraiser organizer Gianine DeFrancesco are seeking $75,000 to help cover medical expenses, insurance gaps and lost income during her recovery. Castmates, including Miranda Rae Mayo, have shared or contributed to the fundraiser.
