Grapefruit link to breast cancer

Eating grapefruit every day could raise the risk of developing breast cancer by almost a third, US scientists say.

A study of 50,000 post-menopausal women found eating just a quarter of a grapefruit daily raised the risk by up to 30%.

The fruit is thought to boost levels of oestrogen - the hormone associated with a higher risk of the disease, the British Journal of Cancer reported.

But the researchers and other experts said more research was still needed.
