When Andrew Potts got a letter inviting him to have his lungs checked, he didn't think much of it. But as the clinic was right next to his local Asda, he tied in a visit whilst getting his tea.
A few weeks later, he received a call saying doctors had found a nodule in his right lung. A biopsy arranged for him at Wythenshawe Hospital showed he had cancer.
Andrew, 60, a retired policeman from Denton, who was working as a civilian officer at the time, thought his general ill health at the time had been due to the fact he was working late shifts.
