Concerns and concerns about the skin are concentrated in summer when the sun is burning, but in fact, caution should be taken in winter. It is because of ultraviolet rays. When enjoying skiing or snowboarding, the sunlight reflectance of snow or ice reaches 85-90%, requiring efforts to block UV rays.
◇Winter UV rays can't be relieved...about 90% reflectance of snow and ice sunlight
Skin cancer is caused by a variety of causes. In particular, excessive exposure to sunlight for a long time causes damage to skin cells due to ultraviolet rays and increases the risk of cancer.
In winter, in addition to direct ultraviolet exposure, sunlight can be reflected by snow or ice, increasing the amount of ultraviolet exposure, so special attention is needed when outdoor activities.
Common skin cancers include basal cell cancer, squamous cell cancer, and malignant melanoma.
Among all skin cancers, basal and squamous cell carcinomas account for about 85% and malignant melanoma account for about 10%.
Basal cell carcinoma occurs due to abnormalities in the basal cells at the bottom of the epidermis and appears mainly on the face, which is the area of sunlight exposure.
It is rare to spread through the bloodstream or lymph nodes, but it infiltrates directly into surrounding tissues and destroys normal tissues, drilling through bones. Basal cell carcinoma is translucent in Westerners and often appears in the form of an ulcer in the center and a round circular border around it. However, Asians often start with pigmented spots, so they are often mistaken for spots and left unattended.
Squamous cell carcinoma is common on the face, the back of the hand, arms, lower lip, and auricles. The shape can take many forms, including nodules, warts, and ulcers. It generally appears to be a red, scaly spot.
Malignant melanoma invades hands, toes, nails and nails, soles of the feet, face, back, and shin well.
It is similar to a black spot due to its appearance as a spot or nodule, but is characterized by the lesion not symmetrical and irregular boundaries. If the color is diverse and the diameter is more than 6mm, the spot with spots is itchy, and if it is loose, it is likely to be melanoma.
Doubtful if there is continuous change in the color and size of the ◇ dot or if there is pain
To prevent skin cancer in daily life, it is important to reduce skin damage caused by ultraviolet rays. It is recommended to refrain from outdoor activities during times with strong UV rays and apply sunscreen carefully 20 minutes before going out. It is also advisable to wear mass production, hats, long sleeves, and sunglasses to avoid ultraviolet rays. Indoor tanning is also an important cause of skin cancer, so it is recommended to avoid it.
Like other cancers, skin cancer can be cured if detected early. Cancer progeny such as photokeratosis or shallow basal cell carcinoma can be removed by medication, cryotherapy, or laser treatment without surgery. If the ▶ size is more than 6mm or has an asymmetric shape, if the boundary of the ▶ point is unclear, if the ▶ color is not uniform, if the color or size of the ▶ point has been changing steadily for several months, ▶ if there is a change in human face (scale), crust (bug), ulcer, or bleeding, ▶ If there is itchy or stinging, pain, etc., it must be treated accurately.
Professor Seo Soo-hong of the Department of Dermatology at Korea University Anam Hospital advised, "When you have suspicious pigmentation spots in areas with high sunlight exposure, such as your face or neck, or erythema accompanied by rough dead skin when touched, it is recommended to get an accurate diagnosis from a dermatologist. People who are frequently exposed to UV rays should pay special attention to skin damage caused by UV rays, such as applying sunscreen regularly."
