Citrus Linked to Skin Cancer in New Study

Researchers have found a correlation between citrus intake and malignant melanoma in a preliminary study, according to a report published in the Journal of Clinical Oncology. Scientists from Brown University and Brigham and Women’s Hospital compiled observational data on 41,000 men in the Health Professionals Follow-Up Study and 63,000 women in the Nurse’s Health Study, both of which spanned over 20 years from the mid-1980s through 2010.

Researchers discovered a 10 percent increased risk of skin cancer in participants who ate citrus two to four times per week, compared to those who ate citrus less than twice per week on average. Risk of developing melanoma increased with the amount of citrus consumed. Those who ate citrus more than 1.5 times in an average day were 36 percent more likely to develop skin cancer compared to those who ate it less that twice per week. Only grapefruit and orange were included in the study.

Cutaneous malignant melanoma is a potentially life-threatening form of skin cancer. Although there have been recently incredible advances in the treatment of melanoma, melanoma prevention through the use of sun protection and skin cancer screening is recommended,

said senior author Dr. Arbar Qureshi of Brown University and Rhode Island Hospital.

However, there is no need to cut back on citrus fruit just yet. The study found only a correlation, so there is not necessarily a causal relationship between citrus intake and melanoma risk. Further research is needed to clarify the study’s findings.
