Ms. Redstone, who is trying to close the sale of her family’s Paramount media empire to Skydance, was diagnosed with thyroid cancer this spring.
Shari Redstone, the chair and controlling shareholder of Paramount Global, is confronting a personal health crisis as she navigates a high-profile battle over the future of her media empire and a lawsuit filed by President Trump against her news division at CBS.
Ms. Redstone, 71, was recently diagnosed with thyroid cancer and underwent surgery last month, she acknowledged in an interview after The New York Times asked about her condition.
“Shari Redstone was diagnosed with thyroid cancer earlier this spring,” said Molly Morse, a spokeswoman for Ms. Redstone.
The diagnosis adds a new layer of complexity to the legal and political quagmire that Ms. Redstone and her company, which controls television stations, streaming platforms and a movie studio, have been struggling to navigate.
Ms. Redstone said she sought medical attention about two months ago after experiencing fatigue and other symptoms. She received the diagnosis the next day. Surgeons removed her thyroid gland but were unable to remove all of the cancer cells because they had spread to her vocal cords.
Ms. Redstone continues to be treated with radiation, and “she and her family are grateful that her prognosis is excellent,” Ms. Morse said. “While it has been a challenging period, she is maintaining all professional and philanthropic activities throughout her treatment, which is ongoing.” She was recently involved in the selection of three new Paramount board members.
