What pisses me off is my mum has been suffering from cancer for 10 years now and not once has she ever been told to wear a mask to protect her from seasonal flu or virus which can kill anyone having chemo.(except this year) When I recently asked this to a 'health professional' she could not give me an answer. The typical shrug of the shoulders and a generic 'I cant answer that'. She was however wearing a face mask and face shield.
