A team of international researchers has revealed that an amino acid found in a variety of foods including asparagus has been linked to the spread of breast cancer.
Published in medical journal Nature, the study adds to a growing pile of evidence that suggests diet can influence the course of the disease.
Senior author Gregory Hannon at England's University of Cambridge, said: 'The study results are extremely suggestive that changes in diet might impact both how an individual responds to primary therapy and their chances of lethal disease spreading later in life.'
'This study may have implications not only for breast cancer, but for many metastatic cancers,' he further claimed.
Investigators now are considering conducting an early-phase clinical trial in which healthy participants would consume a diet low in the amino acid. Studying the effects of this could also alter treatments for other types of cancer.
