Harvard warns of high calcium-prostate cancer link

The researchers concluded, "These findings may serve to interject a note of caution into the current enthusiastic promotion of a higher intake of calcium in the US." However, Dr. June Chanl, lead author of the report, told HealthWorld, "This is a 'head's up' rather than the sounding of an alarm.
