Joe Doering, a professional wrestling competitor, dies at age 44 following a long illness involving brain tumors. Multiple outlets report that he was diagnosed with a brain tumor in 2016, which led him to leave wrestling at that time. They also say he later received two additional diagnoses about a decade after his first, after which his condition progressed to a battle described as brain cancer. Fox News and other reports state that Doering competed in promotions including AJPW (All Japan Pro Wrestling) and TNA Wrestling, and that he held multiple championship titles there. The Mirror adds that his final period of illness followed a third brain tumor diagnosis. Reports also note that the wider pro wrestling community and fans share condolences on social media following his death. Other outlets describe his illness as lasting for around ten years, covering time between his initial 2016 diagnosis and his death at 44. Details on his medical treatment and the exact circumstances of his death are not provided in the excerpts.
