The youngest patient to ever have gender reassignment surgery is to go under the knife for the third time after deciding she is ready to go through life as a woman.

Ria Cooper was born a boy, named Brad, but at 15-years-old, realise she identified as a girl, and was Britain's youngest sex-swap patient.

But three years on, she became swamped by the new life, and felt scared she may never be accepted as a woman.

Ria Cooper was born a boy, named Brad, but felt she was in the wrong body by the age of 12. Right, as a woman in 2012, when she had decided to end treatment

She stopped treatment just before the surgery and became Brad again.

Speaking to the Sunday Mirror, she has revealed she is now living as a woman again, and is ready to finish the treatment.

Now 23, she said: 'I've always known I was female – it was everyone else who was confused, not me. I was wearing make-up and heels at the age of 12, there was no question.

'Only now I realise that made me even more unhappy. Now I’m going to be me – and I hope I will finally be happy.'

She feared she would never be accepted as a woman but has now decided that she will go ahead in the hope she will be happy

Ms Cooper is now trying to silence her critics by paying for much of her own treatment.

She paid £5,000 for her 34EE breasts and will have gender change surgery next year.

She also revealed that her transition ended the first time as she feared she would never find love as a woman, because men dumped her when their friends found out her past.

Ms Cooper also claimed her transition cost her a job, but is now looking to open a beauty clinic for transgender people, and hopes to become a mother.
