Noel Edmonds has reignited a row with Phillip Schofield over whether negative attitude can invoke cancer.
The pair had a tense exchange on This Morning over the summer after Deal Or No Deal host Noel said he got cancer after "going through a very stressful, very negative period in my life."
Phillip asked: "The stress in your life gave you prostate cancer?"
And Noel raised the topic again on Thursday after tweeting the This Morning presenter what appeared to be a quote from a Harvard University study.
Philip replied, raising issue with the way Noel had presented his ideas before the former Noel's House Party presenter told him "your ego is larger than your intellect".
He also accused Phillip of corrupting the truth and making "a fool of yourself."
The argument ended when Noel decided his point had been proved.
