Claira Hermet: I'm choosing to have a double mastectomy
1Xtra presenter Claira Hermet, 27, has chosen to have a double mastectomy after losing her mum and sister to breast cancer.
"Doctors will scoop all of the insides of my boobs out," she says.
"In the same operation I'll have a reconstruction as well."
Doctors have told Claira there is an 85% chance she will develop breast cancer as she has inherited a mutation in her BRCA 1 gene.
"One way I do not want to die is of breast cancer."
She is due to have surgery in January.
Newsbeat will track her over the next few weeks. She will also be the focus of a documentary for BBC Radio 1 Stories, due to be broadcast later in 2015.
