exposure to the sun or other sources of ultraviolet radiation (RUV), such as sun beds, make up the main cause of aging and the development of skin cancer, RUV causes cumulative and irreversible damage to the skin structure. For this reason, it is very important to avoid sunlight from an early age.
“Skin cancer is the most common cancer in humans: 1 of 3 will be skin. Discovered on time, it is cured in most cases. " the doctor explained Ana de pablo, Subtitled Dermatology at the University Hospital of Australia and Professor at the Faculty of Biomedical Sciences at the University of Australia.
Despite preventive measures and early diagnosis, skin cancer cases have increased worldwide over the past two decades. And Argentina does not avoid this increase.
“Raising public awareness about preventive measures is a fundamental principle. In this sense, it is important that people learn to independently verify their personal knowledge and learn injuries that may be new, change and motivate consultations with a specialist. Also, educate to acquire healthy habits against the sun, minimize the risk of burns and reduce the accumulation of damage RUV "– confirmed De Pablo.
diagnostics Cancer still has a negative charge for people. This is perceived as a moment without a return and no possibility of survival, but this is a false idea that leads to the isolation and stigmatization of people.
According to the records of the nation’s Ministry of Health, 9 out of 10 cases of skin cancer are associated with sun exposure. The reason for this is that the skin continuously absorbs ultraviolet radiation, emitting sunshine throughout life.
is an that a person at the age of 18 is already exposed to 80% of all UV rays that will be absorbed throughout his life, hence the importance Take healthy habits in the face of sun exposure throughout the year, not only in the summer, but also conduct frequent inspections of peas in person, as well as with a specialist.
Within National Campaign for the Prevention of Skin Cancerthe doctor Alejandro Turek, A specialist in clinical oncology (MN 65.164), suggested some recommendations to take into account to avoid injuries when exposed to the sun now that the summer season is approaching.
"The time has come when everyone is exposed, whether it be outside, in swimming pools or on beaches, in the sun." Some of the darker skins have more luck and sunburn, as well as others, but others with lighter skin should be careful and not be neglected in every show. "– the expert assured.
Yes and no, when it comes to protecting the skin from the sun
According to the specialist, skin that takes care of sun damage, especially in youth, has a much lower risk later to show signs of photo preparation or injuries, such as skin cancer.
“The more exposed to the sun, the greater the risk, UV rays damage DNA, our genetic information, UVA generates skin aging, wrinkles or blemishes over time, and repeated exposure to ultraviolet radiation from the sun is considered by science the biggest risk factor for cancer skin, the most common tumor of all, affecting the largest organ of all "said Turek.
"Skin redness is a direct reaction to the sun and is common in people with color and light eyes, but dark skins do not go through this stage, but they light up directly, but they are also damaged in the long term, so it is always recommended to use protection, although it is ideal that Do not expose your skin if you want to achieve a tan, better to be progressive, especially in the early days of exposure. ”
Here is a series basic precautionsto be taken when exposed to sunlight:
– This is fundamental avoid exposure to sunlight at noon, between 11 and 16 o'clockBecause at this moment the shadow cast by the body is shorter, and the sun shines from the center of the sky with great intensity.
– Infants and young children should not be exposed to the sun for up to 6 months (mainly because until now they can not use defenders) and up to 3 years, at least, they are protected by cotton clothes, hats and SPF more than 15.
– Application sunscreen This is important with every exposure to the sun.
– There is a big variety sunscreen types that fit every skin type and the situation. But it is extremely important to use a broad-spectrum protective product (with UVB-UVA filters) with a sun protection factor of 30 or more.
– After selection sunscreen is necessary to place the product half an hour before exposureso that the skin can absorb the active ingredients.
The defender must be updated every two hours and then out of the water (sea, lake, pool, stream, river, waterfall) or excessive perspiration. It is also important to place a sufficient amount of cream. It is recommended approximately 2 milligrams per square centimeter of skin.
– In addition to applying the cream, use proper accessories that increase sun protectionFor example, UV protection sunglasses, wide-brimmed hats, or caps with a visor.
– The defender should Apply to all skin exposed to the sun. and special attention should be given in areas such as ankles, neckline or head in the case of natural bald or shave.
Ritual hydration It is recommended to spend the morning before the start of the day, and then apply sunscreen
– It should not be used only transparent clothes although it feels colder because t-shirts or raster pants closed and dark colors better protect the skin from the rays.
– While it is exposed to the sun and especially on hot days, it is necessary drink plenty of fluids (approximately 2 to 3 liters per day) and increase the intake of fruits and vegetables.
– After each exhibition also, the skin must be hydrated in order to continue to protect it. It is recommended to use “post-sun” creams so that the skin does not hurt.
Ultraviolet radiation and, in particular, solar radiation, are carcinogenic to humans and cause all major types of skin cancer, such as basal cell carcinoma, squamous cell carcinoma and melanoma.
Skin self-analysis, an ally for early detection
through an ABCDE technique or pigmented lesion rule is evaluated; its asymmetry, edges, color, diameter, and also its evolution. If you have a pigmented lesion or what we usually know as a mole, you should evaluate the following characteristics: its asymmetry, detection of undefined or raised edges, differences in color tones, diameters of more than six millimeters, changes in time and the presence of symptomatic lesions, for example , painful or causes itching or ulcers.
After the diagnosis, it is necessary to find out what type of melanoma and at what stage it is, and on the basis of this, treatment and prognosis are established.
“This is an emblematic action that stimulates SAD, characterized not only by providing free care, identifying suspicious lesions of possible skin cancer in those people who voluntarily attend checks, but are also accompanied by photo-education measures, with a vision of raising public awareness of behavior prevention,” says Dr. Cristina Pascutto, a dermatologist and president of the Argentine Society of Dermatology.
