Vitamin A, found in everyday veg such as broccoli and carrots, could treat pancreatic cancer.
The disease, which killed actor Patrick Swayze in 2009, takes 7,500 British lives a year. But researchers found that injecting vitamin A into healthy cells surrounding the cancer helped to combat it.
Dr Hemant Kocher, of Barts and The London NHS Trust, said: “We found that paying attention to the non-cancerous tissue surrounding the cancer is as important as focusing on the cancer. It’s a significant milestone in the battle against this disease.”
