But the 66-year-old's plans spiralled into a nosedive when doctors would not grant her permission to do a skydive.
Disappointed at her plummeting charity plans, Mrs Hancock's good-willed grandson stepped up to take her place.
The Swiss Valley gran had planned to leap into the skies above Swansea on Saturday, July 19.
Battling a type of cancer known as non-Hodgkin's lymphoma, Mrs Hancock wished to do the jump for Ty Bryngwyn Hospice Appeal and the chemotherapy unit at Prince Philip Hospital. But sadly, due to her condition she was regarded as not fit enough to take part.
"I'd love to have done it," she said. "I just wanted to give something back."
Set to strap on her parachute instead is her 20-year-old grandson Adam Fussell.
The father-to-be will be jumping for his cancer-fighting gran, but also in memory of Elizabeth, his other grandmother who sadly lost her 13-year battle with cancer.
On finding out his gran could not take part, Mr Fussell said: "I was gutted, and she was really gutted as well. But it was weird because I felt relieved that she couldn't do it, for her sake.
"She asked me if I would still do it and I said 'no problem'. It will be an experience to say the least."
Growing up, the student, Asda employee, and rugby player spent a lot of time with his grandparents, so was enthused about supporting the cause.
Despite having previously jumped 6,000ft from a mountain in Turkey, he has admitted to being a bit scared.
"The parachute was on my back and was already open then, but it's nothing quite as extreme as this," he said.
Mrs Hancock, who is on the Ty Bryngwyn Hospice committee, said: "I'm very proud of him. His other grandmother died of breast cancer two years ago so he is doing it in memory of her as well."
Not unfamiliar with helping out charities, Mr Fussell said: "We have chosen these charities as they do a great deal for the community in helping people.
"We picked the chemotherapy unit as they helped my grandmothers a lot with their battles with cancer.
"Also Ty Bryngwyn Hospice has been a great support to my grandmother, trying to keep her life on track and not focussing on the battle."
