A form of covert treatment that sends a "scout" enzyme into a tumor to single it out for destruction has been developed, scientists say.
The Institute of Cancer Research project showed the drugs delayed tumor growth in animal experiments.
The therapy works by identifying tumors and using non-toxic drugs that become active when they hit the target.
Experts said it could "greatly improve" patients' quality of life, but needed to go through human trials first.
Standard cancer treatments, such as chemotherapy, treat cancer anywhere in the body by indiscriminately attacking all cells in the region.
