The best way to reduce the risk of skin cancer - is constantly protect your skin from the sun and ultraviolet radiation.This means that you need to avoid prolonged exposure to the sun, especially at midday, when the sun is high.
Apply sunscreen on the body.It is necessary to properly use sunscreen, and everyone needs to understand how and when to use them.Follow the instructions carefully and apply the cream again, as stated after swimming or sweating.The bottom line is that people should not avoid sunscreens or blockers of ultraviolet radiation, but it should always use them in combination with other sun protection measures.
Many parents are now taking effective measures to protect their children from dangerous and aggressive rays of the sun, although experts fear that they too rely on sunscreen and less - on the other protective measures.
How to reduce exposure to the sun and ultraviolet radiation
We give some concrete recommendations to prevent excessive exposure to the sun:
- Use sunscreens that block both alpha and beta radiation.Do not rely on sunscreen alone to protect from the sun.Wear protective clothing and sunglasses.
- Avoid exposure to the sun, especially from 10 am to 16 pm, when UV rays are the strongest.
- Use precautions, even on cloudy days.Clouds and fog will not protect you from the sun, and in some cases, it may enhance the action of beta-rays.
- Avoid reflective surfaces such as water, sand, concrete, all painted white.
- UV intensity depends on the angle of the sun and not from heat or brightness.Dangers greater closer to the beginning of the summer.
- Skin burns faster at higher altitudes.One study showed that 6 minutes at an altitude of several thousand meters above sea level in the afternoon give a person burns more than 25 minutes at sea level.
- Avoid sun lamps and tanning beds.In machines used mainly alpha rays.
Sun protection clothing
wear protective clothing, sunglasses and a hat to protect your face from the sun.Special clothes can block UV rays.This clothing is expensive, but it is designed to use a sun protection factor (SPF) or "ultraviolet protection factor" system (UPF), and FPU also is the highest and, according to research, it is a reliable indicator of protection.
Everyone, including children, should wear a hat with a wide brim (but even a hat can not fully to protect against skin cancer in the head and neck).
Look for loose-fitting clothes, unbleached, made of thick fabric.Tight Weave - a higher level of protection clothes.
Washing clothes over and over again improves FPU.A simple way to evaluate protection - carried the clothes to the window or lamp and see how much light it gets.The less light, the better.
Everyone older than 1 year old should wear sunglasses that block all ultraviolet sun alpha and beta rays.
When choosing sunscreen look at its composition, ingredients.Drugs that help to block ultraviolet radiation, sometimes classified as sunscreens, in accordance with the substances which they contain.Sunscreens contain organic and inorganic sunscreen formula.Nevertheless, the term "sunblock" is used less and less.And the term "sun" - more and more.
Organic formulas contain UV filtering chemicals - such as octocrylene, octyl salicylate, homosalat and octyl methoxycinnamate (blocker of beta-rays), avobenzone, Parsol 1789 (blocker alpha-rays), sinoksat, ethylhexyl p-methoxycinnamate (blockers of beta raysand a small amount of alpha-rays), oxybenzone and benzophenone-3 (alpha blockers and beta rays).Look at the wide spectrum sunscreens, which contain a combination of these ingredients and filters alpha- and beta-light.
formulas contain inorganic UV-blocking pigments, zinc oxide or titanium dioxide.Zinc and titanium oxides on the skin surface are not absorbed.They prevent almost all of alpha- and beta-rays from the skin effect.Older sunscreens were white, pasty and unattractive, but many products employ the so-called fine or oxides of zinc or titanium.They are transparent and almost the same as the protectors of the old type.
Cheap and expensive products with the same ingredients
Sunscreens will hold 4-star rating at the level of alpha-protection (1 star means very little protection from the alpha-rays).New sunscreen labels will also emphasize the importance of protective clothing for complete protection from the sun.
safety and efficacy of the combination sunscreen and insect repellent products remain unclear.While the sun protection means must be applied often, insect repellents are used too frequently, and may be toxic.
Organic formulas and fine inorganic oxides do not protect against visible light, which is a problem for people who have fair, sensitive skin, including scrapie create problems, porphyria and hronicheskjuj actinic dermatitis.
Sun Protection Factor
SPF calculation (SPF - Sun Protection Factor is) . SPF-ratio based on the amount of UV radiation.It is necessary to make sunscreen sunblock for the red skin.For example, people who acquire a tan for 5 minutes, and who want to stay in the sun for 150 minutes, can use a sunscreen SPF 30.
offer sunscreen protection, which can be classified as follows:
- minimum - SPF 2 toeleven;
- moderate - SPF 12 to 29;
- SPF temperature - 30 +.
maximum protection factor of UV-beta will be increased from 30 to 50 SPF.
SPF levels by age groups.While sunscreens that are safe for most infants and children, they should not be the first and only line of defense.All young children should be well covered with clothing, sunglasses and hats.Keep children out of the sun during peak periods of sunlight.Do not use sunscreens for children aged up to 6 months without consulting a doctor.
Older children and adults (even with darker skin) benefit from the use of SPF 15 or older.Some experts recommend that most people use SPF 30 or higher on the face and 15 or higher on the body.Adults who burn easily - instead of tanning.Vsev who are exposed to risk factors for skin cancer, use SPF 30 or higher.
Apply sunscreen or sunblock follows.Adults should use sunscreen every day, even if you go outside for a short time.Apply a large amount of the cream on all exposed skin, including ears and feet.The level of protection indicates the SPF sunscreen.Experts recommend half a teaspoon of cream on head, neck and each arm, and a teaspoon - on the chest, back and each leg.
Apply sunscreen or sunblock 30 minutes before going out into the open air in order to achieve the best results.During this time, sunscreen is absorbed.Then re-apply it every 15-30 minutes in the sunlight.Also re-apply each time after exercise or swimming, or at least every two hours.Choose a waterproof or water-resistant formula, even if your work does not include swimming.Watertight formula kept for 40 minutes in water, and water resistant of the formula - half length.
Possible dangers when using sunscreen.The use of sunscreens can help to avoid the sun and reduce the severity of skin aging and skin diseases, including squamous cell carcinoma.In this regard, some of the problems: sunscreens do not protect against melanoma and basal cells of some cancers.It is also important to remember that even when using sunscreen during peak hours people should not stay too long in the sunlight.Even if a person tans, alpha rays can still penetrate the skin and cause harm.In addition, some people use sunscreen too little, and it increases the risk of skin aging and skin diseases.

Chemoprevention - this is the use of substances in order to prevent or reduce the risk of cancer.Some drugs are used to block the development of skin cancer, including melanoma.These include the drug imiquimod.It causes the immune system to fight foreign substances, including cancer cells.
chemoprophylaxis of skin cancer - is:
- nonsteroidal anti-inflammatory drugs;
- retinoids, which are indicated for the prevention of non-melanoma skin in patients with basal cell nevus syndrome, dry skin and transplanted organs.Retinoids include Isotretinoin and Acitretin.These drugs can also prevent the development of squamous cell carcinoma in patients who take them to treat psoriasis.
Antioxidants, vitamins and herbal products
Antioxidants are chemicals or drugs that prevent cell damage from unstable molecules called free radicals.Antioxidants help to protect the skin.These include vitamins C, E and coenzyme Q10 (CoQ10).
There are extensive data on the benefits of antioxidants from wrinkles when used in skin creams.To date, only products containing selenium and vitamins C and E, as shown, may help reduce the negative impact on the skin and the sun damage to the skin from the sun.Meanwhile, unfortunately, most available products contain very low concentrations of the useful antioxidants.In addition, antioxidants are not well absorbed by the skin, so the effect may be short-lived.There is also no evidence that they prevent skin cancer.
Note: a wide range of herbal products may contribute to skin problems.Some Chinese herbal creams have been found corticosteroids.In some formulations Ayurvedic therapies are harmful to humans mercury and arsenic were found.Furthermore, some herbal remedies for the treatment of physical or emotional state may cause photosensitivity (irritation in response to sunlight).These include including St. John's wort herb and some rare.
