Breast cancer could be 'stopped in its tracks' by new technique, say scientists

Discovery of method for blocking enzyme that spreads cancer cells to bones is described as 'important progress' in prevention of secondary stage of disease

Certain breast cancers spread to the bones using an enzyme that drills "seed holes" for planting new tumours, research has shown.

The discovery could lead to treatments aimed at preventing secondary breast cancers in patients with non-hormone sensitive disease.
