n Exposure to the sun or other sources of ultraviolet radiation (UVR), such as sunbeds, is a major cause of aging and skin cancer development. RUV causes cumulative and irreversible damage to the skin structure. For this reason, it is essential to avoid sun damage early. "Skin cancer is the most common form of cancer in humans: one in three will be cutaneous." Detected early, it is curable in most cases, explained Dr. Ana De Pablo, deputy chief of dermatology at the University Hospital of Austral and professor at the Faculty of Biomedical Sciences of Austral University.
Despite prevention and early diagnosis measures, skin cancer cases have increased worldwide in the past two decades. And Argentina does not escape this increase. "Increasing public awareness about prevention measures is a fundamental pillar. In this sense, it is important for individuals to learn to perform self-examination for personal knowledge and recognition of injuries that may be new, to change, and to motivate consultation with the specialist. , to educate to acquire healthy habits in front of the sun, to minimize the risk of burns and to reduce the accumulation of damages by the RUV ", said De Pablo.
The diagnosis of cancer still has a negative impact on people. It is perceived as a moment of no return and without possibility of survival, but it is a false idea that leads to the isolation and stigmatization of people.
According to National Health Ministry records, 9 out of 10 skin cancer cases are due to sun exposure. The reason for this is that the skin continually absorbs the ultraviolet radiation that emits the sun for life.
It is estimated that an 18 year old has already exposed to 80% of the total ultraviolet rays that will absorb throughout his life, hence the importance of adopting healthy habits before sun exposure throughout the year, not only in summer , and Perform frequent checks on moles personally as well as with a specialist.
In the scope of the National Campaign for the Prevention of Skin Cancer, Dr. Alejandro Turek, specialist in Clinical Oncology (MN 65.164), offered some recommendations to be taken into account to avoid injury when exposed to the sun, now that the summer season .
"The time has come when everyone is exposed, whether on the street, in the pools or on the beaches, in the sun. Some, those with darker skin, are more lucky and even tanned, but others with lighter skin should be alert and not neglected in each exhibition, "said the expert.
Yes and no, to protect the skin
According to the expert explained, a skin that is cared for by sun damage, especially in youth, has much less risk after showing signs of photoaging or skin lesions such as skin cancer.
"The more exposure to the sun, the greater the risk." UV rays damage DNA, our genetic information. "UVAs cause aging of the skin, they crinkle or stain us over time. science the greatest risk factor for the development of skin cancer, the most frequent tumor of all, affecting the largest organ of all, "said Turek.
"Skin redness is an immediate reaction to the sun and is common in people with fair skin and eyes." The darker skins do not pass through this stage, but they brown directly, but they are also damaged in the long run, so the protection is Although it is ideal not to expose the skin, if you are looking to get a tan, it is best to be progressive, especially during the first few days of exposure. "
l It is essential to avoid sun exposure at noon, between 11 and 16 o'clock, as at this moment the shadow projected by the body is shorter and the sun shines brightly from the center of the sky.
l Babies and small children should not be exposed to the sun until 6 months of age (mainly because they can not wear protectors at this time) and up to 3 years at least protect them with cotton clothing, hats and SPFs greater than 15
l There is a wide variety of types of sunscreens that match every skin type and situation. But it is crucial to use a broad spectrum protection product (with UVB-UVA filters), with a sun protection factor of 30 or greater.
l Once the sunscreen is chosen, the product must be placed half an hour before exposure, so that the skin can absorb the active ingredients.
l The protector should be renewed every two hours and then leave the water (sea, lake, pool, stream, river, waterfall) or perspire excessively. It is also important to put a sufficient amount of cream. Approximately 2 milligrams per square centimeter of skin is recommended.
l In addition to applying cream, appropriate accessories should be used to increase sun protection, such as sunglasses with UV protection, wide-brimmed hats or visor caps.
l The protector should be applied to all skin exposed to the sun and special attention should be paid to areas such as the ankles, neckline or head in case of bald or natural shaved skin.
The hydration ritual is recommended to perform in the morning before starting the day and then apply sunscreen
l You should not only wear light clothing, even if you find it cooler, because T-shirts or pants with closed weaves and dark colors better protect the skin from lightning.
l When exposed to the sun and especially on hot days, drink plenty of fluids (approximately 2 to 3 liters per day) and increase fruit and vegetable intake.
l After each exposure, in addition, the skin should be moisturized to continue to protect it. The use of "post-solar" creams is also recommended so that the skin is not injured.
Ultraviolet radiation, and in particular solar radiation, is carcinogenic to humans and causes all major types of skin cancer, such as basal cell carcinoma, squamous cell carcinoma, and melanoma.
Through the Abcde technique or rule, a pigmentary lesion is evaluated; its asymmetry, borders, color, diameter and also its evolution. If someone has a pigmented lesion, or what we commonly know as a mole, the following characteristics should be assessed: their asymmetry, detecting undefined or raised edges, differences in color tones, diameters greater than six millimeters, changes over time time, and the presence of symptomatic lesions, for example, painful or causing pruritus or ulcers.
Once the diagnosis is made, it is sought to establish what type of melanoma is and what stage it is in, and based on this, a treatment and a prognosis are established.
"This emblematic action that drives SAD is characterized not only by the provision of free care, to detect suspected lesions of possible skin cancer in those who voluntarily participate in check-ups, but also is accompanied by measures of Photo-education, with the vision of sensitizing the population to behaviors to prevent pathology, "says Dr. Cristina Pascutto, dermatologist and president of the Argentine Society of Dermatology.
