A Shetland woman has been telling how a search for a gene variant alerted her to her breast cancer diagnosis.

Christine Glaser, from Whalsay, had been a participant in Viking Genes, a research project that looked at the genetic make up of people from the Orkney and Shetland Islands.

Since those tests were taken, the understanding of the significance of certain genes has improved and last year geneticists sought special permissions to go back to those who took part in the study to ask if they wanted to know their results.

Although she had lost a sister to ovarian cancer, the family was unaware many of them carried a BRCA 2 gene variant that increased their risk of breast, ovarian and prostate cancer.

Christine’s cancer was caught early and successfully treated.
