Study Suggests High Citrus Fruit Consumption May Lead to Skin Cancers, Particularly Melanoma!

After studying data carefully, which was taken from two prolonged studies regarding men and women, scientists concluded there could be a probable link between Consuming citrus fruit and malignant melanoma, which is a form of skin cancer.
This study does not confirm whether citrus fruits literally cause skin cancer, further detailed study is needed in order to prove this connection. (according to the Journal of Clinical Oncology)
The results from a solo practical study that may not emulate the entire U.S. Population, should be elucidated very carefully, explained Dr Abrar Qureshi, who is an Author of the Warren Alpert Medical School of Brown University and Rhode Island Hospital.
Mr Qureshi worked on this analysis in alliance with Women’s Hospital in Boston and the Channing Division of Network Medicine at Brigham.
“Cutaneous malignant melanoma is a potentially life-threatening form of skin cancer,” Mr Qureshi added “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.”
Scientists used up data on more than 63,000 females in the Nurses’ Health Study department and 41,000 men in the Health Professionals department. The Follow-Up Study, couple of which were active from the mid-1980s to 2010. Every few years scientists collected data on the dietary pattern that the recipients were following and where both men and women reported health events like melanoma diagnosis themselves, that were tallied with medical records preserved.
The participants gave answers to questions about how often they ate citrus fruits like grapefruit, oranges, grapefruit juice or orange juice, and all of these four food items together was counted as approximately “overall citrus consumption,” though it doesn’t include other citrus fruits like lime and lemon.
After close to 20 years of follow-up, scientists came up with 1,840 cases of melanoma. When compared, people who ate citrus foods less than twice a week, than those who ate citrus two to four times a week, had a 10 percent increased risk of having melanoma.
Risk of having Melanoma went up as citrus consumption increased, shooting to about 36 percent increase in risk for people who ate the fruits more than one and a half times a day, on average. Our of all the citrus fruits, grapefruit seemed to have the largest affiliation with melanoma.
Also depending on the different amounts of sun exposure and the geographical area of the study participants, the affiliation between citrus fruits and skin cancer was still very high, Mr Qureshi claimed.
Citrus fruits that are fresh have furocoumarins in them, which are family of photoactive compounds which have the potential to make a person more sun sensitive, and are prone to make sun exposure more harmful to skin cells, Mr Qureshi wrote to Reuters Health by email.
“We are NOT recommending changing fruit consumption as these fruits and vegetables are important for overall health,” he said. “However, until we learn more about these furocoumarins, those consuming fresh citrus fruits on a regular basis should be extra careful with sun exposure, and depending on their outdoor activities they should wear appropriate sunscreen, hats and sun-protective clothing.”
US is reported to have about 30 cases of skin related malignant melanoma for every100,000 individuals, says Mr Marianne Berwick of the University of New Mexico in Albuquerque.
Melanoma is Infact, fifth most common cancer in the U.S. and sixth most common worldwide, Mr Berwick reported to Reuters Health by writing an email.
The authors of this latest study were extremely cautious to account for the maximum number of explanations they could give, but its still very soon to generalize these results to a common man, she added.
“This study must be replicated in order for it to be used for public health messages,” Berwick said.
