17 April 2016 - Partner writes angry letter to the cancer killing the love of his life.

Last month, asbestos cancer sufferer Deanna Trevarthen was given weeks to live. Her weight had plummeted to 35kg and she was told to get her affairs in order.

The disease had been dormant in her lung for decades - contracted by breathing asbestos fibres as a 10-year-old at her electrician father's work - and was about to claim her.

Chemotherapy had failed and the 44-year-old was given the heartbreaking news she was terminal. Then she started Keytruda.

The Government has been asked to fund Keytruda for melanoma, but it is also used in the US to treat lung cancers, so Trevarthen began using it.

It was a last-ditch attempt. And Trevarthen and her partner Greg Robertson now describe the drug as their miracle.
