When Sinead Watson had a double mastectomy in June 2017 at the age of 26, she was initially ‘quite euphoric.’ Although born female, she had been taking testosterone for two years and was using the name Sean. The mastectomy, or ‘top surgery’, was the last step on her transition.

‘I was so glad that I’d finally got it done – no more binders, no more being paranoid that I was a man with boobs –  so I did feel really good about it,’ she says.
