Eating three portions of raw broccoli or cabbage a month could reduce the risk of bladder cancer by 40 per cent, according to new research.
Scientists from the Roswell Park Cancer Institute in New York surveyed 275 people with bladder cancer and 825 people without.
They found that non smokers who ate at least three servings of raw cruciferous vegetables each month were approximately 73 per cent less likely to develop bladder cancer than smokers who ate fewer than three servings.
Both smokers and non smokers who ate the three portions were 40 per cent less likely to develop the disease.
Cruciferous vegetables are rich in isothiocyanates which are known to reduce the risk of cancer.
According to Cancer Research, approximately 10,100 people in the UK are diagnosed with bladder cancer each year.
It causes around 4,700 deaths annually in the UK.
