The latest news on caffeine and skin cancer

Food Facts came across some great information regarding caffeine intake and skin cancer that we wanted to make sure we brought to the attention of our community.

A new study published here in the United States has linked the increase of caffeine a person’s diet with a lower risk of basil cell carcinoma.  Basil cell carcinoma is the most common type of skin cancer.  The study included over 110,000 people and was published in early July in the journal Cancer Research.

Dr. Jiali Han, an associate professor with Brigham and Women’s Hospital, Harvard Medical School in Boston and the Harvard School of Public Health went on record saying:   “I would not recommend increasing your coffee intake based on these data alone.”  However, he did add that basal cell carcinoma is just one of a growing list of diseases that appear to be positively affected by increasing coffee/caffeine intake.  That list includes diseases like Type 2 Diabetes and Parkinson’s disease.

Most skin cancers  treated in the U.S. are basal cell skin cancers.  This is the type that begins in the epidermis (the skin’s top layer) and results from regular exposure to ultraviolet radiation.  Basal Cell Carcinoma is a slow-growing cancer which is not life-threatening.   However, it still requires costly treatment.  Any finding that helps prevent the disease can have a positive effect on the public health and our over-burdened health care system.

There were 112,897 people taking part in the health study.  Of those participants a little over 22,700 developed basal cell carcinoma during the 20 years of follow up involved in the study.

It was found that the more caffeine participants consumed, the lower their risk of developing Basal Cell Carcinoma.   They then ranked the study participants according to their caffeine consumption and found that in the case of women, the top 20% of consumers had an 18% lower risk of developing the cancer than the bottom 20%.  The risk was lower for men by 13%

For coffee specifically, it was found that women drinking 3 cups of coffee per day had a 21% lower risk of developing the skin cancer and risk for men was 10% lower.  Caffeine from other food and beverage sources were found to have a similar effect.   The consumption of decaffeinated coffee, however did not correspond to a similar decrease in risk.

It was noted that more study is needed that will include different populations.  It is also important to note that the increase of caffeine consumption showed no effect on developing other forms of skin cancer.

Food Facts thinks that the ability to help prevent Basal Cell Carcinoma through an increase in caffeine is just one of the first steps of many to discovering how food and ingredients both positively and negatively can affect our health.  Stay informed.  It makes a world of difference.

Skin Cancer Risk Reduced by Coffee

Brought to you by Foodfacts.com: New research is showing that coffee consumption may help to prevent skin cancer by killing potentially cancerous skin cells. Check out the article below to learn more!

A cup of caffeinated coffee a day helps prevent cells from dying off due to UV rays.

WASHINGTON — Coffee has been shown to reduce the risk of skin cancer by helping kill off damaged cells that could otherwise turn into tumors, according to a US study published on Monday.

The findings indicate that moderate caffeine drinking, or perhaps even applying coffee to the skin, could be useful in warding off non-melanoma cancer, the most commonly diagnosed of all skin cancers.

Using mice that had been genetically altered to suppress a protein enzyme called ATR, researchers showed that the mice were able to fend off cancer even when exposed to ultraviolet light.

Previous studies have suggested that drinking about a cup of caffeinated coffee per day has the effect of suppressing ATR and triggering the die-off of cells harmed by UV rays.

The altered mice eventually did develop cancer, but three weeks later than normal mice, according to the study published in the Proceedings of the National Academy of Sciences.

After 19 weeks of ultraviolet light exposure, the engineered mice showed 69 percent fewer tumors and four times fewer invasive tumors than the control group.

However, the protective effects only went so far. After 34 weeks of UV exposure, all the mice developed tumors.

“Eventually, if you treat them long enough, the mice will develop cancer so it is not 100 percent protection forever,” Allan Conney, one of the study’s authors, told AFP.

“Really, with almost any carcinogen, eventually all the animals will develop tumors,” added Conney, who is director of the Susan Lehman Cullman Laboratory for Cancer Research at Rutgers University in New Jersey.

Conney and his team were able to confirm their hypothesis that caffeine — when consumed or applied to the skin — works by inhibiting ATR. Now they say more studies are needed to see how it may work on humans.

“We want to see whether caffeine has an effect in people when you give it topically,” he said.

“Caffeine might become a weapon in prevention because it inhibits ATR and also acts as a sunscreen and directly absorbs damaging UV light.”

Skin cancer is the most prevalent cancer in the United States, with more than one million new cases each year, according to the National Cancer Institute.

Non-melanoma types of skin cancer, including basal cell and squamous cell types, are the most commonly diagnosed and are often treatable if detected early.

Previous studies have shown coffee drinkers tend to have fewer incidences of breast, uterine, prostate and colon cancers, but the beneficial effects are not seen in people who drink decaffeinated coffee.
