There are rigorous and numerous scientific studies that show that ultraviolet radiation from the sun is the primary environmental factor in the development of skin cancer.

Every year more than 2 million new cases of non-melanoma skin cancer and 200,000 malignant melanomas are produced worldwide, and many of these cases appear to be caused by the sun.

Likewise, the worldwide incidence of skin cancer is increasing, closely linked to a higher frequency of sun exposure in recreational activities and accumulated heatstroke over time.

The carcinogenic effect of ultraviolet rays is linked to its wavelength. They are above all the ultraviolet spectrum B and C of solar radiation, which has the highest induction power of skin cancer since it induces structural damage in cellular DNA and leads to mutations. It has been estimated that a 10% decrease in the stratospheric ozone layer could cause an increase of 300,000 skin cancers worldwide. Also, a reduction of 1% in the ozone layer, UVB / UVC radiation increases by 2% and skin cancer by 2 to 6%. But the adverse effects of UVA radiation should not be neglected either.

How The Sun Main Cause Of Skin Cancer

Ultraviolet rays have a direct carcinogenic effect, apparently influencing the development of various types of lesions: cutaneous pre-cancer, carcinomas, and melanoma.

Skin cancer is divided into several types; the most common are three:

The Basal Cell Carcinoma: is the most common and most challenging to be detected by oncology treatment hospitals In India, it is characterized by invasive and destructive. Despite this growth is slow and has a low risk of metastasis, 70% of cases occur in the face and the head, 15% in the trunk and very rarely in areas such as the penis, vulva or perianal skin.

Squamous cell carcinoma: the squamous cell is at a medium level since it is not the most serious, but for that reason, it is still dangerous, it is characterized by the appearance of lesions of 7 and up to 10 centimeters in the face of the neck and armpits. In comparison with basal cell, your risk of metastasis or spreading is greater. However, if it is detected early, it is curable, and there is very little chance that it will cause death.

Melanoma: finally, melanoma is found, this cancer is one of the most dangerous and originates in the melanocytes, which are the cells that produce the pigment or color in the skin, it is necessary to clarify that the melanocytes also create the appearance of moles, which are NOT malignant, nor cancerous.

Prevention

To prevent this disease Cancer Treatment Hospitals in India suggest that the most important thing is to protect our skin from exposure to ultraviolet rays, it is not necessary to avoid the sun altogether, but you must take precautions when exposing yourselves to it.

One of the simplest ways to defend yourself is the use of sunblock. The other way to protect you is to stay in the shade. With this simple fact, the risks are diminished enough, besides the use of hats or caps, sunglasses with filters for UV rays.
