Cancer drug 'breakthrough'

A massive breakthrough in the fight against cancer was announced today.

Scientists in America revealed they have developed a drug which could cure skin cancer. They believe it could be effective against all cancers.

Experts claim it could lead to potent new drugs capable of completely removing tumours. Initial trials of the drug were so successful researchers admitted they were "surprised and excited". The new drug, called B7-DC, works by allowing the body's immune system to fight cancerous cells.

Professor Larry Pease of the Mayo Clinic in Minnesota, who led the study, said: "It is a major breakthrough and is much stronger than anything else we have seen." Human trials of the drug could begin within 12 months.
