Women who eat red meat every day are almost twice as likely to develop certain types of breast cancer, a long-term study published today has found.
Scientists who monitored 90,000 women for more than a decade found that those who ate a high meat diet were much more prone to developing the hormonally reactive breast cancers, which account for more than half of all breast cancers.

The scientists suggest that synthetic hormones used in meat production could be behind the trend.
