Polly Bamber has a grade 4 glioblastoma multiforme and wants to go to the USA where they have more intensive treatment.
The 39 year old, has started a fundraising page to raise cash to fund treatment she's not eligible for here in the UK.
She told Wish FM there are cases of people heading to the States with the same condition as her and returned in remission.
Polly hopes to raise £120,000 but says if she doesn't reach her initial target of £60,000 then the money will be donated to help fund research in to brain cancer.
The step-mum of two is supposed to be looking forward to her wedding at the end of August but instead this illness is hanging over.
Speaking with Wish FM Polly says the support of her partner Janine Withington and her family is helping her deal with the situation and hopes the treatment will give her more time with them.
