Lifestyle Magazine | Sun and cancer: hard-won ideas


Make sure you put your hat, T-shirt, goggles and, of course, your tube of sunscreen in your beach bag this summer.

Despite prevention reports spread over several years, this is not yet a reflex for many French people: 24% of them – 34% of men and 15% of women, declared in May 2019 do not use sunscreen when exposed, according to a survey conducted by the YouGov Institute (1),

In a statement released at the end of July, the Cancer League warns once again of the dangers of the sun, recalls that sunscreen is paramount, regardless of skin type or tan level, and draws up many misconceptions that remain rooted in the minds of people. Here are seven: then, true or false?

1 / Solar burns are the first step in tanning

FALSE : "In all cases, sunburn is already a skin lesion. light cause in addition to the pain of thickening of the skin. If sunburn is more important (burning, blistering), the skin peeling and gives way to new, more fragile matter, which in turn can burn … It's a vicious circle! "

2 / Under the umbrella I can't take sunburn

FALSE: "On the beach, you are not completely safe under the umbrella. This does not stop the sun's rays reflected by the sand, so there is no sunscreen, goggles and protection. Wind and swimming have a misleading effect … In fact, even the clouds filter out only a small fraction of the UV and if ultraviolet B (UVB) radiation is largely responsible for the harmful effects of the sun, then UVA recognized mutagens are also protected. "

And vitamin D?

Beware, there is no doubt in your mind that the sun is absolutely evil. We need morale and it provides us with vitamin D, but we treat it in a reasonable way.

In order to get enough stimulation of Vitamin D synthesis, it is enough for the skin of the face, hands and arms (about 25% of the body) to be exposed to sunlight for 15 to 30 minutes a week. Therefore, vitamin D is not an excuse for poor sun protection.

If you are afraid of running out, instead of dangerously exposing yourself, it is better to look elsewhere, such as in foods of animal origin, such as meat or dairy products. It is also found in oily fish such as eel, salmon and mackerel, or in vitamin D. enriched margarines.

3 / Anyone can burn, just expose yourself often

FALSE : "Some people, like redheads, make little or no brown pigments that allow tan. If you have very light skin, white hair (albino) or red, freckles that appear very quickly in case of" exposure (phototype 1) or if you have very light skin that can become tanned, blond or light brown, sunburnt freckles (phototype 2), do not try to tan. "

4 / You cannot tan with index 50

FALSE: "No solar product blocks 100% light rays." The term "full screen" has been banned in Europe for about fifteen years and if you have skin that tans, it doesn't mean that you can "If sunburns do not occur as quickly in sunburned people, they still exist." and the skin is damaged. "

5 / Lamp tanning is safe

FALSE: "The sun under a UVA lamp or sunbath is a high risk practice: 50 to 70% of skin cancers are directly related to excessive exposure to UVA and UVB rays."

6 / The sun favors the treatment of certain diseases

TRUE AND FALSE: "This applies to rickets (but 10 minutes of exposure per day is sufficient), psoriasis (in combination with other treatments) and eczema, but is not correct for acne or joint pain (It is better to treat the cause), even if the heat is good. "

7 / No need to monitor moles regularly

FALSE: "The term beauty place refers to several types of pigmented skin lesions: warts, papillomas, nevuses … Only lesions containing cells that produce the pigment melanin, which is called melanocytic nevuses, can cause skin cancer. But when in doubt, a beauty place which changes its appearance, bleeds, spreads, or whose discoloration should result in consultation with its physician or dermatologist. "

Skin cancers: skin cancers and melanomas

Skin cancers are skin cancers are the most common (80% of cases) but also the most treatable skin cancers. They develop on the skin in places exposed to the sun, most of the time after 60 years.

Less common (about 1% of skin cancer) than cancers, the incidence of melanoma is increasing.

Skin melanoma, the number of new cases tripled between 1980 and 2005. It continues to progress by an average of + 3.4% per year over the last period 2010-2018.

Surgery remains the primary weapon for treating early-onset melanoma. In a more advanced stage, treatment with immunotherapy, targeted therapy and / or chemotherapy may be required.

A total of 80,000 new cancers and 11,200 new cases of melanoma are diagnosed every year in France.
