The singer was recently pictured in a wheelchair as the treatment had left him feeling too weak to stand.
Opening up about his illness last October, hopeful Tom expressed a goal to be cancer-free by March.
He also opened up about his health battle in a heartbreaking Channel 4 documentary, Tom Parker: Inside My Head.
Breaking down in tears on camera, he said: “Scared is an understatement. I was petrified. I couldn’t stop thinking about death, is the honest truth.”
He added: “It’s so hard to think about the future, because I genuinely don’t know what it holds any more.”
Tom leaves behind children Aurelia, two, and Bodhi, one, as well as his wife Kelsey, 32.
