Accurate storylines at the heart of Tanya's story.
Two doctors from the Royal Cornwall Hospital have been helping BBC producers with a story in EastEnders.
In the soap, Tanya Jessop, who is played by Jo Joyner, was diagnosed with cervical cancer following a smear test.
Tito Lopes, the clinical lead for gynaecological cancer services, and consultant radiotherapist Alistair Thompson were asked for their advice. Mr Lopes and his team helped to make sure Tanya's story was as close to reality as possible.
