Pee-wee Herman star Paul Reubens’ cause of death revealed

Paul Reubens’ primary cause of death was “acute myelogenous leukemia.”

A copy of his death certificate – which has been obtained by The Blast – shows that the actor was battling blood cancer and metastatic lung cancer before he passed away.

Reubens ultimately lost his life because of “acute hypoxic respiratory failure.” The condition occurs when the respiratory system “cannot adequately provide oxygen to the body, leading to hypoxemia.”

What’s more, the news was shared on Reubens’ official Instagram page.

The announcement also included a personal statement from the actor, explaining why he decided to remain quiet about his cancer battle.

He wrote: “Please accept my apology for not going public with what I’ve been facing the last six years. I have always felt a huge amount of love and respect from my friends, fans and supporters. I have loved you all so much and enjoyed making art for you.”
