Exposing oneself to UV radiation can cause sunburn and, in the longer term, can promote the development of cancers. This is why Australian researchers say that one of the best preventive actions is to apply sunscreen very regularly as early as possible in childhood and throughout adult life.

This is one of the first things to do when it comes to enjoying the summer sun safely. In addition to avoiding exposure between noon and 16 hours and looking for shade, it is essential to apply sunscreen every two hours and after each swim for better protection. And since no cream completely filters the UV of the sun we must choose a high protection index, minimum 30 to be protected. Researchers at the University of Sydney conducted a study showing how adopting this gesture of prevention from childhood and throughout his life is essential to significantly ward off the risk of cancer
Their work has shown that Australians aged 18 to 40 who regularly used sunscreen during childhood reduced their risk of developing a melanoma by 40% compared to those who rarely used sunscreen. In Australia, statistics show that melanoma is the most commonly diagnosed type of cancer in men aged 25-49 and the second most common cancer among women in this age group, after bad cancer. In addition, about two in three Australians will be diagnosed with melanoma or other types of skin cancer by the time they turn 70.
Women are more adept at sunscreen [19659006] With this in mind, the researchers wanted to conduct a study to examine the badociation between the very frequent use of sunscreen and the risk of melanoma in people under 40 years of age. They badyzed the data collected from nearly 1,700 people who participated in a national study called "the Australian Melanoma Family Study" including 600 with melanoma. "Our study shows that the use of sunscreen in childhood and adulthood protects melanomas in young people from 18 to 40 years old, with a 35-40% reduced risk for children. regular users of sunscreen, "says Professor Anne Cust, of the University of Sydney.
It adds:" The badociation of exposure to the sun and sunburns with Risk of melanoma, especially in children, is well established and this study has shown that regular use of sunscreen protects against the harmful effects of sun exposure. This study also found who is most and least likely to follow this recommendation. It turns out that regular users of sunscreen are generally young women s of British or North European origin, with a high level of education, light skin pigmentation and a significant history.
Not all equal in the sun
Conversely, those least likely to use were more male, older, with a lower level of education, and generally dark skin or more resistant to sunburn. "Although sunscreen is widely available and recommended for protection, optimizing its use remains a challenge and controversy continues to surround its use," said Professor Anne Cust before adding that "this study confirms that sunscreen is an effective form of protection and reduces the risk of developing melanoma in young adults. It should be applied regularly during childhood and adulthood when the UV index is high. "
The researchers also reiterate another recommendation of the health agencies that certain population subgroups such as skin sensitive to the sun or with many moles should in no way neglect sunscreen. Because we are not all equal to the UV, as the Inpes explains. "People with skins and / or light eyes, those with red or blond hair and those with a significant number of moles are more likely to be exposed to exposure to the sun . The skin of children up to the age of puberty is thinner and particularly vulnerable to the carcinogenic effects of UV rays.
In France, the number of n new cases of skin cancer more than tripled between 1980 and 2012. According to the Inca, "cutaneous carcinomas account for 90% of skin cancers diagnosed. Less common, melanomas are the most dangerous because of their high metastatic potential. The former usually occur after the age of 50, in the uncovered areas of the body and are most often due to excessive and chronic sun exposure. The latter can be anywhere on the body, including on the scalp. Finally, it is important to note that the sunburns received during childhood significantly increase the risk of skin cancer in adulthood.
