A father, whose son has a rare form of cancer, will be doing a sponsored tandem skydive for the first time this weekend.

The money raised from the event will go towards the Addenbrooke's Charity Trust and from there the money will go towards teenagers and young adults with cancer, aged between 13 and 24, as well as their families.

Stuart Frost, 49, from Coronation Grove, Swaffham, will be carrying out the adventurous activity on Saturday at Beccles Heliport, in Suffolk.

His son, Kevin Frost, 22, from Dennys Walk, Narborough, was diagnosed with Ewing's sarcoma - which starts in the bone - 10 weeks ago.

The former Hammonds High School pupil completed A-levels at the Swaffham school and worked at the reception at Oaks Pool and Gym, in Pentney.

His father will be jumping from 12,000 feet and hopes to raise �1,000, which will go towards a new 11-bed cancer ward at Addenbrooke's Hospital in Cambridge, due to open next month. Kevin will be one of the first people to be treated on the ward.

Stuarts wife, Pam, 52, who is Kevin's stepmother said: 'I think Stuart is looking forward to the skydive. It is probably something he has always wanted to do but now he has got a reason to do it. He doesn't seem nervous.'

Talking about Kevin's illness, she added: 'Everyone is giving him a lot of support and is willing him on. He seems quite light hearted and we have a few laughs with him to keep his spirits up. The family has held together really well. Kevin is really impressed about Stuart doing the skydive.'

The 22-year-old who lives with his mother, Teresa Frost, has spent one week at King's Lynn's Queen Elizabeth Hospital and seven at Addenbrooke's Hospital and has so far had three sessions of chemotherapy and radiotherapy. He is due to complete six separate sessions over 18 weeks.
