Do Orange Juice and Grapefruit Increase Skin Cancer Risk?

A new population study suggests that drinking orange juice or eating grapefruit regularly might increase the risk of developing malignant melanoma skin cancers. This study included data on a total of 63,810 women from the Nurses' Health Study and 41,622 men from the Health Professionals Follow-Up Study. Eating grapefruit more than three times weekly was linked to a 41% increased risk of melanoma. Drinking orange juice, but not eating oranges, was linked to a 25% increased risk.
