Can coffee prevent skin cancer?

Coffee is a tempting drink, and it’s a good time to relax with a cup of coffee, whether during work or at rest. In addition, coffee seems to have anti-cancer effects, let’s take a look at the latest research results brought by Yahoo!

The little friends who love coffee, your gospel is coming. A new study shows that people who drink coffee regularly can effectively fight malignant melanoma, which is the main cause of skin cancer death in the United States.

In this study, the experimental group of people drank at least four cups of coffee a day, and they were 20% less likely to have malignant melanoma than the control group. The findings were published in the National Cancer Institute.

Erikka Loftfield, the lead author of the study and a member of the National Cancer Institute, said that although the findings are encouraging for coffee drinkers, “not that people should change themselves. “The habit of drinking coffee”, “To reduce the risk, the most important thing is to reduce sun exposure and ultraviolet radiation.”

“Our findings, as well as other recent research results, have made coffee lovers more comfortable, at least they made it clear that drinking coffee is not an adventure.” Loftfield in an email This tells Life Science, “However, our findings do not suggest that everyone change their habit of drinking coffee.”

Review of the experimental process

Previous studies have found that drinking coffee reduces the risk of malignant melanoma. Melanoma is formed in pigment cells, which are called melanocytes. According to the National Cancer Institute, in 2014, 9710 patients died of the disease and 76,100 new patients were diagnosed.

Loftfield and her team analyzed a large amount of data from a joint tracking experiment conducted by the National Center for Health Research and the American Association of Retired Persons, which conducted a 10-year follow-up of 447,357 retirees. Eventually, there were 2,904 patients with malignant melanoma (the cancer cells had spread deep into the skin) and 2,874 early melanoma patients (the cancer cells remained on the surface of the skin). Loftfield said, “Our research is currently the most valuable study of the relationship between melanoma and coffee.”

Participants provide their daily coffee consumption, as well as other factors that are at risk for cancer, such as exercise, alcohol intake, and body mass index. To capture participants’ UV exposure, the researchers collected the amount of light that NASA obtained at each person’s home.

Is the prevention effect of coffee really optimistic?

The results of this study are mainly for coffee containing caffeine, excluding coffee. The researchers say that caffeine is probably a protective factor for the skin, but there is another possibility. There is another ingredient in coffee that prevents melanoma. Caffeine-containing coffee contains more preventive ingredients than decaffeinated coffee.

The lack of such preventive effects of decaffein may also be an accidental factor, Loftfield said.

The researchers plan to look for evidence of coffee to prevent skin cancer from experiments in another group of people, but Loftfield pointed out that the results of the study are limited: the researcher does not know the daily skin care habits of the subjects, nor do they know Their original skin color (people with dark skin and people with freckles are more likely to develop skin cancer). In addition, it is not clear which specific coffee is really effective for the skin.
