A father has become the youngest man in the UK to have a double mastectomy
Giles Cooper, 56, was devastated when doctors told him he had the same strain of cancer which killed his dad and uncle.
Just 350 men are diagnosed with breast cancer annually, less than one per cent of the 55,000 women that suffer from it every year.
Mr Cooper, a chartered surveyor, had a double mastectomy to save his own life and is now urging men to check themselves regularly for lumps in their breasts.

Mr Cooper, who lives with wife Nicola, 51, in Conderton, near Tewkesbury, Glos., lost his dad Stephen to breast cancer in 2004 who died aged 77.
Two years later, Mr Cooper's uncle Christopher, who was Stephen's brother, died of the same disease, also aged 77.
After their deaths, Mr Cooper had regular check-ups but in August 2014 he discovered a small lump, which doctors discovered was grade 2 invasive cancer which had spread to both breasts.
