Diane Keaton Cause of Death: Verified Health History and Recent Decline
Reported health events over decades give context but do not replace an official medical finding.
The actress faced documented skin cancer issues beginning in early adulthood. She was diagnosed with basal cell carcinoma at age 21. Later reporting noted a squamous cell diagnosis that required two surgeries.
Her own interviews mentioned a family history of skin cancer and a later commitment to regular sun protection. Those comments appear in multiple on-the-record profiles and offer context, not causation.
Eating and recovery
She publicly discussed past struggles with bulimia and described binge-purge cycles earlier in her career. She credited therapy and analysis with helping her recover, saying this shaped part of her personal narrative.
Recent months
“Her health had declined very suddenly,” a source told People.
That statement came from a named outlet source and has been reported without an official medical cause. The information helps explain why friends and family cited privacy in recent weeks.
| Item | Verified detail | Relevance |
|---|---|---|
| Early cancer | Basal cell at 21 | Documented diagnosis |
| Later cancer | Squamous cell; two surgeries | Surgery confirmed in coverage |
| Eating disorder | Bulimia; recovery via therapy | Publicly discussed in interviews |
| Recent decline | Source: “declined very suddenly” | Reported, not medically confirmed |
Summary: Verified health history includes early basal cell and later squamous cell cancers, plus past eating disorder disclosures. None of these verified items has been presented as the official cause of death; they provide factual background while respecting family privacy.
Signals from a Private Final Chapter: Social Media, Daily Routines, and Home Sale
Public markers in her final months suggested a quieter, more private routine than fans had grown used to. Reports noted reduced social media activity and several lifestyle changes that appeared in public records and neighborhood accounts.
Reduced social media activity and the April 2025 National Pet Day post with her dog
Her social media activity slowed in the months before news broke. The last notable social media post came in April 2025 — an Instagram media post that celebrated National Pet Day with her dog, Reggie.
A Brentwood neighbor said she used to walk dog daily but had not been seen doing so in recent months. The neighbor recalled her signature hat and sunglasses and described friendly, chatty exchanges on the sidewalk.
“She always talked to her dog like a person,” the neighbor remembered.
In March 2025 she listed a Los Angeles home for $29 million and cut the price to $27.5 million two months later. The property had been called a dream home, though listing moves fit a pattern; the actress often bought and flipped high-end homes.
- Marked slowdown in social media contrasted with prior monthly posts.
- Final national pet post featured Reggie and a lifestyle collaboration.
- Neighbor accounts noted a change in daily walk dog routines during the months before her passing.
- Real estate activity — listing and price reduction — added a public signal about the home and property plans.
Summary: These observable signals — fewer posts, a final pet day tribute, altered routines, and high-profile property moves — form part of a public timeline. They inform reporting without implying any medical conclusion and respect the family’s request for privacy.
