On 25 January 2013, he gave an interview to
John Wilson on the
BBC Radio 4 arts programme
Front Row. He discussed his cancer and said doctors had told him he had nine or ten months to live.
However, Johnson did not have the more common
adenocarcinoma of the pancreas. It was later discovered that he had a
pancreatic neuroendocrine tumour (PanNET), a less aggressive and more treatable form of the disease. Johnson underwent radical surgery to treat his illness, and the doctors were hopeful that his prognosis would be good.At the
Q Awards on 22 October 2014, Johnson accepted the "Icon Award" and announced that he was "cancer-free" having undergone "removal of his pancreas, spleen, part of his stomach, small and large intestines and the removal and reconstruction of blood vessels relating to the liver". Johnson said: "It was an 11-hour operation… This tumour weighed 3kg – that's the size of a baby! Anyway, they got it all. They cured me. It's so weird and so strange that it's kind of hard to come to terms with it in my mind.
