Coffee and coffee caffeine consumption regularly is associated to ameliorated risk of basal cell carcinoma of the skin, the Queensland Institute of Medical Research study suggested.
Coffee, becoming a popular and social beverage all over the world, particularly in the West, is a drink made from roasted bean from the Coffea plant, native to tropical Africa and Madagascar.
Basal cell cancer (BCC) is the most common type of skin cancer characterized by abnormal growth of the cells in the lowest layer of the epidermis.
In the study among 1,325 randomly selected adult residents of a subtropical Australian community collected in 1992, 1994, and 1996, returned food frequency questionnaires from participants showed a significantly lower relative risk in people with with prior skin cancers by 25% with daily consumption of four cups of regular coffee.
Caffeine, a chemical stimulant found abundantly in caffeinated products, including tea and coffee is a class of methylxanthine having a profound impact in central nervous system (CNS).
For people without previous history of skin disease, consumption of neither caffeinated nor decaffeinated coffee regardless of amount intake expressed no risk of basal cell carcinoma.
Dr. Miura K, the lead author said, " Among people with prior skin cancers, a relatively high caffeine intake may help prevent subsequent BCC development. However, caffeine intake appears not to influence the risk of SCC."
Squamous cell cancer(SCC),is another type of skin cancer arises from the uncontrolled multiplication of transformed malignant cells in the middle layer of the epidermis. In the later stage, the disease can spread to organs and tissues distant away from the original site.
Additionally, in the evaluation of the effects of tea, coffee, and caffeine related to early-onset BCC from data of 767 non-Hispanic Whites under age 40 in Connecticut. BCC cases (n=377) identified through Yale's Dermatopathology database and controls (n=390) of individuals in the same database, participants interview revealed combined regular consumption of caffeinated coffee plus hot tea expressed a strong inverse association of early-onset BCC.
Further analysis and after taking into account of other con-founders, risk of BCC was reduced by as much as 43% in this group in compared to non drinking group.
Researchers at the study also indicated that the efficacy in reduced risk of basal cell carcinoma of the skin from these 2 beverages may be attributed to chemical component of caffeine in expression of antioxidant and immunomodulating activities.
Promisingly. in the support of caffeine administration in prevented squamous cells skin cancer development, the Nurses' Health Study and the Health Professionals Follow-up Study, postulated the following results.
1. Caffeine intake from all dietary sources was inversely associated with BCC risk even people who only consumed less than 1 cup of caffeinated coffee per month.
2. Women who consumed more than 3 cups/d had the relative odd risk ratio of 0.79, in compared to 0.90 in men with the same cups intake.
3. Decaffeinated coffee consumption showed no association in decreased BCC risk.
The finding evidences expressed that coffee and coffee caffeine consumption have a significant effect in reduced risk of basal cell carcinoma of the skin, particularly in people with previous skin cancer.
But some researchers had raised questions that the efficacy of coffee in reduced risk of BCC may be attributed to other components in the coffee as many variables and co-factors have not been taken into the studies.
