According to his death certificate obtained by The Blast and PEOPLE, Reubens died as a result of 'acute myelogenous leukemia' and 'acute hypoxic respiratory failure'.
This complication happens when 'the respiratory system cannot adequately provide oxygen to the body, leading to hypoxemia'.
In addition to being diagnosed with blood cancer, Reubens ‘was also battling metastatic lung cancer’.
The death certificate also confirmed Reubens was to be cremated and laid to rest at the Hollywood Forever Cemetery.

Reubens was best known for his portrayal of Pee-wee Herman, including the 1985 film Pee-wee's Big Adventure, directed by Tim Burton.
Before starring in movies and TV shows in the 1980s, the Pee-wee Herman character developed as a stage act that quickly led to an HBO special in 1981.
However, as a result negative media attention towards Reubens in 1991, the character took a long break from TV.

In 2016, Netflix's Pee-wee's Big Holiday marked his return, but ended up being Reubens’ final feature film before his death just seven years later.
