Parker was immediately sent for an MRI scan and remained in the hospital for three days having tests. It was then that the doctors pulled a curtain around his bed and told him their diagnosis.

“We are all absolutely devastated but we are gonna fight this all the way,” he wrote on Instagram after announcing his diagnosis in October. “We don’t want your sadness, we just want love and positivity and together we will raise awareness of this terrible disease and look for all available treatment options.”

“It’s gonna be a tough battle,” Parker said, “but with everyone’s love and support we are going to beat this.”
