HealthInternationalLifestylePrint Scientists link alcohol consumption to skin cancer risk by: – February 5, 2014 Sharecenter_img 37 Views   no discussions LONDON, England, Wednesday February 5, 2014 – With the consumption of alcohol already linked to seven different types of cancer, scientists are on the verge of adding an eighth, following a study indicating that drinking too much alcohol could set off a chain reaction in the body that makes it more vulnerable to skin cancer.The authors of the work in the British Journal of Dermatology say that ethanol is converted to acetaldehyde soon after ingestion and this compound may render the skin more sensitive to harmful UV light.The results of their research, which looked at 16 different studies involving thousands of participants, suggest that the daily consumption of one or more alcoholic drink increases skin cancer risk by a fifth.The greater the alcohol intake the greater the risk, moreover, with persons who drank 50g of ethanol daily up to 55 percent more likely to develop melanoma, the deadliest form of skin cancer, compared with non-drinkers or persons who only drank occasionally.Melanoma usually starts in the skin and sometimes within a mole. The most common sign of melanoma is the appearance of a new mole or a change in an existing mole. This can happen anywhere on the body, but most often the back, legs, arms and face are affected. In most cases, melanomas have an irregular shape and more than one colour, and they may also be larger than normal moles and sometimes itch or bleed.One of the study authors, Dr Eva Negri from the University of Milan, said: “We know that in the presence of UV radiation, drinking alcohol can alter the body’s immunocompetence, the ability to produce a normal immune response.“This can lead to far greater cellular damage and subsequently cause skin cancers to form. This study aimed to quantify the extent to which the melanoma risk is increased with alcohol intake, and we hope that armed with this knowledge people can better protect themselves in the sun.”The researchers nevertheless admitted that other forces may also be to blame. Drinkers may be less vigilant about exposure to UV radiation, staying in the sun without enough protective clothing or sunscreen.Caribbean Media Corporation Sharelast_img read more
