Naming and shaming doctors for missing cancer symptoms is "not going to make any real difference," one GP told ITV News.
Dr. Chaan Nagpul said: "We mustn't get into the situation where we are blaming doctors for presentations that are difficult to diagnose."
He added: "If cancer was a simple condition to diagnose at an early stage it wouldn't be a killer disease. It's a killer disease because it does actually deceive the patient and deceive the doctor."
Were doctors names and would be worried that the system would quickly become clogged up as doctors began referring everyone who had the faintest possibility of cancer to hospital, he said.
He added: "It may reduce access for those patients to specialists to those patients who do have cancer."
