Emma Mhic Mhathúna, one of the women at the center of Ireland’s cervical cancer controversy, has died at the age of 37.

The Co Kerry mother-of-five was diagnosed with cervical cancer in 2016 after receiving two false smear test results from US-based lab Quest Diagnostics. Earlier this year, she was told her cancer was terminal.

In a statement, her family said she died in the "knowledge that she had helped to shine a light on important issues which affected not just her own life, but the lives of many others.”
