Cancer specialists renew cash call

Cancer specialists and MPs have renewed calls for an additional �100m a year funding for cancer.

Speaking at the Britain Against Cancer Conference organised by Ian Gibson MP, chairman of the All Party Parliamentary Group on Cancer, they urged the government to match the funding offered by the cancer charities.

Sir Paul Nurse, director general of the Imperial Cancer Research Fund, said: "We need to have a long term strategy - one which enables basic research to be turned into real patient benefit.

"The funding must be there to follow long-term plans."

Professor Gordon McVie said that charities funded about 95% of cancer research in the UK at the moment.

'Give children better false limbs'

Children should get more realistic looking false limbs on the NHS, a Conservative MP has said.

Speaking in the Commons, Julian Lewis mentioned the case of Laura Giddings, a 14-year-old constituent of his who lost her leg after a bomb exploded at a restaurant in South Africa.

He said there were few realistic looking limbs available on the NHS and this added to the psychological trauma of children with amputations.

He called on the government to "at least" refund the value of an NHS limb to parents who chose to buy a realistic private one, as happens with patients who buy their own wheelchairs.

Leader of the House Margaret Beckett suggested Mr Lewis should raise the issue with Health Secretary Frank Dobson.
