London, July 22 -- Researchers are applying evolutionary theory to cancer by changing treatments before tumours have time to develop resistance. Mathematical models suggest that rapid, carefully timed switches between multiple therapies could improve cure rates.

A new study suggests that doctors may be able to improve cure rates by switching therapies before a tumour has the opportunity to recover. Instead of waiting for the cancer to return after the initial therapy, the researchers recommend changing to a different treatment while the tumor is still shrinking.

The strategy is designed to address one of the biggest obstacles in cancer care: drug resistance.
