Shari Redstone, chair of Paramount Global, has been diagnosed with thyroid cancer, a spokesperson for Redstone confirmed Thursday.

Shari Redstone continues professional activities despite thyroid cancer treatment, as she works toward resolving the Trump lawsuit against CBS and finalizing Paramount's merger with Skydance Media.

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.
