Like Nick MacInnes, former minister Conor Lenihan also benefitted from a sharp-eyed doctor. A surgeon saw what he believed might be a tumour on Mr Lenihan's cheek as he watched the politician being interviewed on 'Prime Time' (right) in 2007.
The next day he called Mr Lenihan's office and left a message. Mr Lenihan, then 43, phoned back and the surgeon advised him to see a specialist.
Doctors at the Mater Hospital carried out tests and found a tumour on his salivary glands, which was then surgically removed and found to be benign.
However, if it had been left untreated it could have damaged the nerves in his face.
