Freddy Vallender is a funny and brave four-year-old boy from Somerset.
The tumour causes dangerous heart arrhythmias making little Freddy's heart beat in excess of 200 beats per minute and potentially leading to sudden death or cardiac arrest.
It seems that no UK surgeon is capable of successfully undertaking this operation and the little boy will have to go to the Boston Children's Hospital which has an outstanding success record.
The family and friends are raising the £100,000 to pay for the treatment in the US but the real question is why on earth is the NHS not even able to make a contribution to the cost?
The Dame will be making a contribution and hopes her kind readers will do so also. LINK
It seems all sorts of fripperies are available on the NHS but saving the life of a little boy is not considered a sufficient 'frippery'.
