Joe Exotic has apparently made up his mind -- he will die behind bars and refuse further treatment -- because his medical team believes his prostate cancer spread to his bladder.
In a letter obtained by TMZ, Joe says he's recently had a lot of blood in his urine and has been bleeding a lot during his prostate cancer treatments. Joe met with his urology specialist Wednesday who thinks Joe's cancer has spread to his bladder.
While Joe says his specialist wants him to go through some testing to be 100%, he's decided he won't seek treatment, writing, "I want to stay here and just let it take its course.”
It's unclear just how much longer Joe has to live, but he makes one thing very clear -- he won't stop his fight for justice, saying, “The world has to know just how corrupt our justice system is … If I have to be the one to die innocent in here fighting for the truth maybe people around the world will finally speak up for the truth for once.”
TMZ broke the story, Joe recently wrote up a new will, leaving everything to his fiancé, Seth Posey, who he met over the internet.
Joe's clearly still got Seth on his brain, ending his most recent letter by saying, "I could care less about dying, my birthday is coming up soon and all I want is to see Seth.”
For what it's worth ... the 59-year-old still has about 20 years left in his prison sentence.
