Diane Keaton's Cancer Journey

Oscar-winning American actress Diane Keaton passed away on October 11, 2025 at the age of 79. The actress, best known for her role in ‘Annie Hall’, died of pneumonia as confirmed by her family in an exclusive interview with People magazine. In addition to her remarkable achievements in film, Keaton was recognized for her willingness to speak openly about her personal health issues, such as her battles with skin cancer and bulimia when she was younger.

Keaton was diagnosed with basal cell carcinoma, a type of skin cancer, at the age of 21. She had to undergo multiple biopsies before her diagnosis was confirmed. In an interview with Los Angeles Times in 2015, she shared, “It’s a family history. I remember my Auntie Martha had skin cancer so bad they removed her nose. My father had basal skin cancer and my brother had it. It’s tricky with this skin cancer.” Years after her initial diagnosis, Keaton was further diagnosed with squamous cell carcinoma which required her to undergo two surgeries.

Despite her cancer diagnoses, she admitted that she did not take skin and suncare seriously until she was in her forties. She shared, “​​Back in my twenties I didn’t pay attention much. I didn’t research and didn’t really care and that was stupid because it’s dogged me my entire adult life, even recently. I didn’t start sun care until my forties.”

Keaton eventually became committed to skincare and raised awareness on the importance of sun protection. She was the ambassador for L’Oreal Paris for a few years, during which she shared that she has since started keeping a bottle of sunscreen on her all the time. “That’s what I do, I just keep it in my pocket,” she shared.

Keaton even took it a step further in her sun protection. Her signature hats and turtlenecks were not just a fashion statement but also served as a practical way to protect herself from the sun. Her public openness and advocacy for skin cancer prevention through sun protection and skincare, albeit subtle, inspired many.

Keaton’s legacy extends beyond the cinema and lives on as she is remembered as an advocate for skin cancer prevention. To many, she is a symbol of strength and resilience. Her openness about her health conditions has helped break the stigma surrounding skin cancer. She also brought into the spotlight the importance of skincare and sun protection, encouraging regular checkups and early intervention.
