Avoiding and detecting skin cancer: the advice of the dermatologist

Interview with Dr. Joelle Sébaoun, dermatologist. This specialist doctor gives plenty of advice around the prevention of skin cancer ....

If you had a message to spread about cancer prevention, what would it be?

Watch out for the sun! The sun is the first generator of wrinkles and skin cancers. It is absolutely necessary to protect children. But if there was a message to pass, it would be with adolescents.

Children are the responsibility of parents. But with teenagers, it's more difficult. They want to be tanned. They have risky behaviors in all areas, including with the sun. But since 1980, when I go to the office, I see more and more young people suffering from skin cancer. People in their forties. And that is people who have exposed themselves young and have not been careful.

Are sun creams a good protection?

Of course ! But that is not enough. This does not prevent anything. It is necessary to baste with cream, it is obvious but not only. It is absolutely necessary to avoid the sun between noon and two, when it is at its zenith. And we must cover ourselves. You have to put t-shirts, hats, glasses. It's imperative for children. And again, we must also pass this message to adolescents.

What other prevention advice, could you give?

You have to consult a dermatologist if you are in doubt. This is very important as soon as one has a spot that appears or spreads or a mole that changes appearance. Dermatologists have a small device called a dermatoscope. It looks like a little pen. We put it on the suspect spot and we know right away if it is something benign or not. In fact, it is an illuminated magnifier, which measures the size of the mole. And in any case, the ideal is to go regularly consult his dermatologist, it's the best.

The skin is a very important tissue of the human body. If it were spread on the ground, it would cover an area of 1.5 to 2 m² (in adults).

17 Skin Info

The skin represents about 15 to 20% of our body weight. For a person who weighs 75 kg, this amounts to a weight of almost 14 kg.

The skin has on average 6 million cells, 15 sebaceous glands and 100 sweat glands per cm².

In total, the skin includes 3 layers in total: epidermis, dermis and hypodermis . Each layer has very different functions.

The upper layer, the epidermis, protects us mainly from heat, cold and chemicals . It is covered with very many bacteria that live on the surface of the epidermis.

17 Skin Info

The epidermis is particularly thick on the hands and feet where its diameter can reach up to 2 mm . The average thickness of the epidermis is 0.05 mm.

The cells of the epidermis multiply at such a speed that the complete epidermis is completely renewed in the space of only one month . The body loses each day between 10 and 15 grams of dead cells.

Below the epidermis is the dermis : it consists of a very dense network of collagen fibers that give the skin its elasticity and deformability, as well as its resistance to tearing .

In the dermis are blood and lymphatic vessels, nerves, cells of the immune system, hair roots, multiple skin glands and pressure receptors (for the sense of touch).

When it is cold, the small blood vessels of the dermis "tighten", when it is hot they widen. This also has an impact on the color of the skin .

17 Skin Info

The layer below the dermis, the hypodermis, consists mainly of fat and connective tissue. The grease serves as a reservoir of energy and thermal insulator .

17 Skin Info

The hypodermis allows the mobility of the skin and connects it to the underlying structures.

On the hands and especially the feet, the fat of the hypodermis also serves as a " mattress " to protect the bones and tendons that it covers.
