The food you eat could influence the growth rate and spread of cancer, a new study has found. According to scientists at the Cancer Research UK Cambridge Institute, breast tumours in mice struggled to grow without the dietary nutrient asparagine, which is found in asparagus, poultry, seafood and many other foods. When mice with an aggressive form of breast cancer were placed on a low-asparagine diet or given drugs to block the amino acid, their tumours struggled to spread. Scientists hope to be able to take advantage of cancer’s so-called culinary addictions in the future and develop new treatments based on certain foods. Prof Charles Swanton, Cancer Research UK's chief clinician, said: "Interestingly, the drug L-asparaginase is used to treat acute lymphoblastic leukaemia, which is dependent on asparagine. "It's possible that in future, this drug could be repurposed to help treat breast cancer patients." But before you ban asparagus from your home, be aware that more research is needed, including trials in humans. Also, because asparagine is present in so many foods, it is almost impossible to avoid. Baroness Delyth Morgan, the chief executive at Breast Cancer Now, said people should not drastically alter their diets as a result of this research. "We don't recommend patients totally exclude any specific food group from their diet without speaking to their doctors,” she said.
