Promises of magic bullet treatments to eradicate any form of cancer should always be approached with the utmost caution, but a new method of tackling breast cancer does appear to hold out immense promise.
The drug triggers the immune system into attacking a protein found in most breast cancer cells and tests on mice show that it stops cancer forming and arrests the growth of existing tumours.
If those results were replicated in clinical trials involving women, it would be a monumental breakthrough in the fight against a common and deadly form of cancer. It may also herald a new way of tackling other forms of the disease. Sadly, it could take a decade before these hopes are realised.
