Along with her two daughters, Warboys resident Sue Webster will attempt a 13,000- foot tandem jump next month to thank Addenbrooke's Hospital, who helped her father recover from two bouts of cancer.
Sue said: "The skydive is to say a huge thank you to Addenbrooke's and to raise awareness that, if cancer is caught early enough, a full recovery can be made."

Sue will take part in the skydive at the North London Parachute Centre in Chatteris, Cambridgeshire next Wednesday (August 6) along with her daughters Claire, 19, and Katie, 16.
When Sue's father Ian Hook, 70, recovered from bowel cancer in 2003 she thought it would be an end to the pain and worry he had suffered since being diagnosed with the illness.

But in March this year he was back in hospital undergoing a seven-hour operation to remove his cancerous oesophagus.
And things went from bad to worse when he contracted pneumonia – and then septicaemia – a week after the surgery.
The 70-year-old was then moved into neurosciences critical care unit at Addenbrooke's Hospital – the only place which had a spare intensive care bed.

Sue said: "Things looked very bleak to start with but with the treatment and because of the amazing care he received from the teams at Addenbrooke's he was able to go home after eight weeks of surgery."
A couple of weeks later he returned for a check up and was told by hospital consultants they believed they had removed all of the cancer and that he would not need any more chemotherapy.
Sue, who works at RAF Wyton, admitted that when it comes to jumping out of the plane, she will be a bit nervous.

She said: "I will be absolutely petrified.
"But it was either a skydive or a marathon, and having done a couple of marathons before I know how much preparation is needed."
