A man who was told he had anxiety and advised to "breathe into a paper bag" later died of brain cancer.
Keith Evans was 21 when he collapsed during a suspected panic attack in February 2010. He then developed painful headaches and was given tools to manage his "anxiety".
Weeks later during a visit to his GP, he was referred for an MRI scan where he was diagnosed with a glioblastoma, a fast-growing and aggressive brain tumour. Despite being given six months to live, Keith survived five-and-half years.
