Alcohol is a well known risk factor for numerous health issues, including different cancers.
It was found that nearly 4% of all cancer cases all over the world are linked to alcohol consumption. Numerous studies show that esophageal, colon, pancreatic, liver, and breast neoplasms may occur because people misuse strong drinks.
The reason is probably about chemicals, released during alcohol metabolization.
Scientists claim that ethanol transforms into acetaldehyde in the body. This substance can damage DNA and impair repairing processes.
In addition to this, new research found that not all beverages are equally harmful for our health.
A team of investigators from Brown and Harvard universities analyzed data from three large researches in order to find out, whether alcohol intake may increase risks of developing the most aggressive type of skin cancer – melanoma.
Melanoma grows from pigment-contained cells, situated in the top layer of our skin. While this is the least common type of skin malignancy, it was recognized as the most deadly. According to statistics, approximately 10 000 American people die from this disorder annually.
Prolonged exposure to UV radiation, including sunlight and tanning lamps, was recognized as a main risk factor for melanoma.
During the study, conducted by Dr.Cho and her colleagues, more than 210 000 participants were asked to complete questionnaires about frequency, amount and type of alcohol, they take in.
After 18 years of following-up, results found that each alcohol-contained beverage elevates risks of melanoma occurrence up to 14%.
But the main surprise was that daily glass of white wine was associated with 13% higher chances of getting melanoma, while red wine, beer and liquor haven’t shown significant effect on this type of cancer.
It’s also interesting that those who consumed 20 grams of alcohol or more, were more likely to have melanoma on the body areas, less exposed to sunlight like trunk.
Specialists explain that white wine includes higher amount of acetaldehyde than red wine. In addition to this, red wine is full of antioxidants such as resveratrol that can mitigate harmful influence of acetaldehyde.
So if you want to take some wine, you’d better choose the red one. And remember that the American Cancer Society advises limiting your alcohol intake to one beverage for women and two – for men.
