Debbie Brewer travelled to a clinic in Frankfurt after UK doctors said they could do nothing for her.
She had developed mesothelioma through contact with her father, an asbestos lagger at Devonport dockyard, when she was a child.

She was granted a six-figure compensation sum because her illness was caused by hugging her father and spent the money on treatment at The University Clinic in Frankfurt.

"I never thought it would absolutely annihilate it."
Now she is supporting Mesothelioma UK to get the treatment on the NHS.
The charity is meeting politicians, doctors and researchers next week.
