Who does not spend the whole year dreaming of a vacation on a beach, with the warmth of summer and with a bright sun that browns our skin? And it is normal that when the good weather arrives and the temperatures rise we want to be outdoors and take advantage of the longest days of the season, but it is very important not to overlook the protection of our skin. Now that we have more knowledge of the damage that the sun can cause us, there is no reason not to apply sunscreen and other protectors. The long list of harms from excessive sun exposure goes through freckles, wrinkles, skin color change, capillary dilation, and collagen destructionBut it ends in an even more terrible consequence: the formation of benign tumors and cancer cancers.
What causes skin cancer?
Skin cancer occurs due to the division and uncontrolled growth of cells. The two main types are melanomas and skin carcinomas, and for both the main risk factor is UVB and UVA solar radiation, especially in people with light skin and eyes. While melanomas only constitute 5% of tumors and form in generally covered places, such as the back and legs, cutaneous carcinomas are much more frequent and their incidence has increased in recent years. Carcinomas usually appear on the hands, face, and neck, especially after age 50.
How to identify them?
If you notice any injury or change in your skin, you should immediately go to the dermatologist. But there are some telltale signs:
Reddish spots that may bleed and scab over
- Ulcers that do not heal
- Irregular edges
- Different colors in the same injury
- Change of appearance
- Greater than 0.2 inch
But it is not enough to apply sunscreen
A recent study by scientists at the University of Manchester in the UK concluded that sunscreen is not enough to protect you from the damaging effects of UV rays. To prevent melanoma, they also recommend wearing hats and being in the shade as long as possible. Dr Julie Sharp, Director of Health Information at Cancer Research Center UK explains that people tend to think that once they apply sunscreen they are "invincible" and may be in the sun longer, which makes them spend more hours exposed to UV rays. "This study provides important evidence that sunscreen plays a role, but that you shouldn't just rely on that if you want to protect your skin," adds Dr. Sharp.
