All most everyone drink coffee in the morning, but a new study suggest it could actually reduce the risk of Melanoma skin cancer. A study carried out in The study, carried out by researchers from the National
Cancer Institute at the National Institutes of Health (NIH) and Yale School of
Public Health at Yale University in New Haven, CT, is published in the Journal
of the National Cancer Institute. The researchers found that the more coffee participants consumed each day, the less likely they were to develop melanoma during the follow-up period. Drinking four cups of coffee a day, for example, was associated with a 20% lower risk of melanoma, the team reports.
The more coffee consumed, the
lower the risk of melanoma.
To detect the team assessed data
from the NIH-AARP Diet and Health Study, involving 447,357 non-Hispanic white
participants who were free of cancer at study baseline.
The participants completed a food
frequency questionnaire at the beginning of the study - which detailed their
coffee intake - and incidence of
melanoma among subjects was monitored over an average of 10.5 years. During
this time, 2,905 participants developed melanoma.
The researchers found that the
more coffee participants consumed each day, the less likely they were to
develop melanoma during the
follow-up period. Drinking four cups of coffee a day, for example, was
associated with a 20% lower risk of melanoma, the team hearsay.
These results remained even after
accounting for participants' age, sex, body mass index (BMI), alcohol
intake, smoking history and ultraviolet (UV) radiation exposure - a primary
risk factor for skin cancer.
The team notes the association
was only found among participants who consumed caffeinated coffee, not
decaffeinated. In addition, coffee only appeared to reduce the risk of
malignant melanoma, not melanoma in situ - in which melanoma cells have not
spread beyond the outer cells of the skin.
"Higher coffee ingestion was associated with a modest
decrease in risk of melanoma in this large US cohort study. Additional
investigations of coffee intake and its constituents, particularly caffeine,
with melanoma are warranted."
The team believes this "self-effacing" reduction in
melanoma risk from coffee consumption, however, may have big effects.
"Because of its high disease burden, lifestyle modifications with even
modest protective effects may have a meaningful impact on melanoma
morbidity," they add.
Talking to MNT, Loftfield said
their findings do not indicate that individuals should increase their coffee
intake to reduce the risk of skin cancer. "The most important thing that
individuals can do to reduce their risk of melanoma is to reduce sun and UV radiation exposure," she added.
While many studies have
documented the positive health effects of coffee consumption, it is important
to note the potential harms. The main ingredient in coffee is caffeine, a known
stimulant. But consuming too much caffeine may lead to insomnia, nervousness,
irritability, restlessness, fast heartbeat, muscle tremors and stomach upset.
