No cause of death has been announced at the time of publication for Keaton. Due to her past with skin cancer, though, fans speculated about the effects from the illness.

Diane Keaton’s Health Issues Before Her Death

The major health issue that Keaton lived with was skin cancer. During a 2015 interview with the Los Angeles Times, the late Something’s Gotta Give actress opened up about how the illness ran in her family.

“It’s a family history,” she explained. “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. That’s why you’ve got to put the sunblock on.”

Keaton was diagnosed with basal cell carcinoma when she was in her 20s, then she was diagnosed with squamous cell cancer decades later. The second diagnosis required two surgeries to remove, according to the Times.
