The daughters of a cervical screening campaigner who tragically died of cancer aged just 31 have written to Theresa May as part of their mum's legacy. Brave Natasha Sale petitioned for the threshold for screening to be lowered from 25 to 18, after being diagnosed with cervical cancer in 2016. Her online petition reached 100,000 signatures, but Natasha tragically died just days after Christmas, on December 28. Now, two of her four daughters, Ella and Lily, have written a letter to Prime Minister Theresa May - thanking her for signing Natasha's petition.
