Katherine LaNasa: Biography, Age, Cancer Diagnosis, The Pitt Role

When Katherine LaNasa stepped onto the set of The Pitt in late 2024, she brought more than three decades of acting experience and a recent breast cancer diagnosis, a hard-won commitment to sobriety, and a deep desire to honor the nurses who cared for her. It’s a combination that made her Emmy-winning performance as Nurse Dana Evans feel deeply personal—and that’s only part of the story.

Born: December 1, 1966 · Birthplace: New Orleans, Louisiana · Known for: Actress, former ballet dancer, choreographer · Notable Role: Nurse Dana Evans in The Pitt (2025) · Spouse: Dennis Hopper (1989–1992), Grant Show (2012–present)

Six key facts about Katherine LaNasa’s life and career, one pattern: resilience across health, family, and professional reinvention.

What was Katherine LaNasa’s diagnosis?

Breast cancer type and stage

• LaNasa was diagnosed with stage I breast cancer in February 2023, a fact she shared in a first-person essay for Women’s Health (health and wellness magazine). The tumor was located right of her sternum.
• She attributed part of her cancer narrative to long-term stress and alcoholism, according to the same essay.

Timeline of diagnosis and treatment

• The diagnosis came after an annual mammogram followed by additional mammograms and biopsies, as reported by HELLO! Magazine (celebrity and lifestyle news).
• Treatment began in March 2023 and included surgery plus about three weeks of daily radiation (Women’s Health).
• LaNasa completed treatment about a year before filming The Pitt, but lingering issues persisted until roughly six months before production, per CBC Arts (Canadian public broadcaster).

The implication: early detection gave her a path to complete recovery in under a year.

How old was Katherine LaNasa when she had her daughter?

• LaNasa gave birth to her daughter Eloise at age 47, according to biographical details she shared with Women’s Health. She has two children total, including a son.
• Becoming a mother later in life features prominently in her public narrative about resilience and stress management.

The trade-off: later motherhood meant balancing cancer treatment with parenting a young child.
