Jonnie Irwin shared an update with his followers on his health battle.
The former A Place In The Sun presenter took to Instagram to reveal he was undergoing Hyperbaric Oxygen Therapy. A hyperbaric chamber is a highly-pressurized room or tube where a patient is given pure oxygen to breathe.
The 49-year-old announced last year that he has lung cancer which spread to his brain, with the diagnosis classed as terminal.
