Lifestyle Magazine | Sun and cancer: tough ideas


This summer, in your beach bag, don't forget to put on your hat, your shirt, your glasses and of course your tube of tan.

Despite the preventive messages that have been circulating for several years, this is not yet a reflection for many French people: 24% of them – 34% men and 15% women – declared in May 2019 not to use sun protection when exposed, according to a survey by YouGov – Institute (1).

In a statement released in late July, the Cancer League once again warns of the dangers of the sun, reminds that sunshine is most important, regardless of skin type or skin level, and compiles the many misconceptions. which remain rooted in the heads of men. Here are seven: So, true or false?

1 / Sunburn is the first step in tanning

FALSE : "In all cases sunburn is already a skin lesion. light It causes, in addition to the pain, thickening of the skin. If the sunburn is more important (burning, blisters), the skin peel and gives way to a new, more fragile fabric that in turn can burn … It's a cowardly circle! "

2 / Under an umbrella, I can't take sunshine

FALSE: "At the beach, you are not completely safe under an umbrella. This does not interfere with the sun's rays reflected by the sand, so it does not provide sun protection, eye protection and protection." wind and swimming have a damaging effect … In fact, even clouds filter only a tiny fraction of ultraviolet rays, and if ultraviolet B (UVB) radiation is largely responsible for the harmful effects of the sun, then UVA, a recognized mutagen, is also protected. "

And vitamin D?

Be careful, you can't say that the sun is an absolute evil. We need it for morale and it provides us with vitamin D, but deal with it reasonably.

To obtain sufficient stimulation of vitamin D synthesis, the skin of the face, arms and hands (about 25% of the body) is sufficient to be exposed to sunlight for 15 to 30 minutes a week. Vitamin D is therefore an excuse for poor sun protection.

If you are afraid of exhausting it, instead of exposing yourself dangerously, it is best to look for it elsewhere, for example 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 margarines fortified with vitamin D.

3 / Anyone can do just fine, just expose yourself often

FALSE : "Some people, such as red skins, do little or no brown pigmentation, which allows them to tan. If you have very light skin, white hair (albino) or red, frequencies that appear very quickly in the event of exposure (phototype 1), or if you have very light skin that can become tan, blond or light brown, the frequencies appearing in the sun (phototype 2), do not try to tan. "

4 / You can't tan with index 50

FALSE: "No solar product blocks 100% light rays." The term "total screen" is banned in Europe about fifteen years ago, and if you have tan skin, that doesn't mean you can. is damaged. "

5 / Trim under a lamp is safe

FALSE: "Twisting under a UVA lamp or sunshine is a high risk practice: 50 to 70% of skin cancers are directly linked to overexposure to UVA and UVB rays."

6 / The sun favors the treatment of certain diseases

TRUE and FALSE: "This is true for rockets (but 10 minutes of exposure daily is enough), psoriasis (in combination with other treatments) and eczema, but it is wrong for acne or joint pain. (It is best to treat the cause), even if the heat is good ".

7 / It is not necessary to regularly pay moles

FALSE: "The term mole refers to several types of pigment lesions of the skin: warts, papillomas, nevi … Only lesions containing cells producing melanin pigment, which is called melanocyte nevi, can cause skin cancer. But in doubt, a mole who changes their appearance, bleeds, spreads or whose color changes should lead to consulting their doctor or dermatologist.

Skin cancers: carcinomas and melanomas

Lucky carcinomas are skin cancers. The most common (80% of cases), but also the most cured skin cancers. They develop on the skin in areas exposed to the sun, most often after 60 years.

More common (about 1% of skin cancers) than carcinomas, melanoma cases are increasing.

Behavioral melanoma, saw its number of new cases triple by 1980 to 2005. And continues its progression of + 3.4% per year on average over the recent period 2010-2018.

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

In total, 80,000 new carcinomas and 11,200 new cases of melanoma are diagnosed in France each year.
