A lot of people in the NHS hate the Cancer Drugs Fund - the pot of money dedicated to funding expensive cancer drugs for patients in England.

This is because the CDF - a fund that will have £340m next year - exists to pay for treatments that would not be bought were cancer subject to normal NHS cost-benefit rules. 

Cancer patients are given more support than other patients.

This is seen as a problem for two reasons. 

First, basic fairness. Why care more about cancer than other diseases? Second, it undermines the cost-benefit system that officials and doctors work hard to make work for the rest of the NHS. 

There remains one big undiscussed element to this, though.

The CDF is a "stop-gap". That's what everyone says. 

Andrew Lansley, the former health secretary, said the fund "is not, and was never intended to be, a permanent solution" to the problem the NHS keeps raising about cancer drugs often costing too much.
