She made the decision to stop after Christmas if she wants to I think - well that's how I interpreted this part
" 'When you're in terrible pain, you make decisions.'
She told hosts Phillip Schofield and Amanda Holden: 'I want my husband and children to see me off happy, contented.
'So I put the chemotherapy in a box.
'In this box, I could stop the chemotherapy after Christmas - I'm determined to hang on until Christmas.
'If my quality of life fades after that, I want to be able to open the box, make a choice and stop the chemotherapy"
