Doctor Reveals Sad Last Words With Shannen Doherty: 'Wasn't Ready To Leave'

Shannen Doherty was a relentless beacon of inspiration until her very last breath.

The Beverly Hils, 90210 alum's oncologist and friend Dr. Lawrence D. Piro of Cedars-Sinai Medical Center in Los Angeles shared his last conversation with the star in the days leading up to her death during a recent interview with People .

“We kept going until we couldn't go any more. The last conversation that we had, she was in the process of realizing that things had taken a pretty significant turn. The conversation was about love and support and caring and still fighting through. She wanted to continue to take treatment and fight through, even though her physical condition had taken a bit of a downturn. And so we did.”

He continued, citing the standout's ability to remain level-headed as she went head to head with her condition.

"I was always amazed with the way in which she could separate her own emotions about being so young and being on such a difficult journey from the fact-finding part. She was so razor focused and level-headed about those things.”

Doherty, who passed away on Saturday (July 13) following a lengthy battle with terminal cancer, revealed that she planned to start chemo again (two weeks before she died ) during a June podcast episode of Let's Be Clear with Shannen Doherty on iHeartRadio. Piro noted his beloved patient's persistence, referring to the actress as an "incredible warrior."

"That wasn't even open for discussion, because that's not how Shannen lived. She was an incredible warrior in everything she did. She fought so hard and she didn't believe that it would ever be over, which kind of makes everybody around you believe that, too, because you want to believe that.”

Doherty is remembered by her family, friends, co-stars, and the lasting impact she left on the entertainment industry.
