MIAMI. – World Melanoma Day is May 23. The American Society of Cancer points out that melanoma is a type of cancer of the fur which appears when melanocytes, cells that give the skin its tan or brown color, begin to grow uncontrollably.
Although it is a less common cancer than other skin cancers, melanoma is dangerous because it is more likely to spread to other parts of the body if it is not diagnosed and treated early.
The American Cancer Society indicates that melanoma is also known as malignant melanoma and cutaneous melanoma. In this way, he points out that “the majority of melanoma cells continue to produce melanin so that melanoma-type tumors are usually brown or black. However, some melanomas do not produce melanin and may appear pink, pale, or even white.”
According to the World Health Organization (OMS), in recent years more than 1.5 million cases of skin cancer have been diagnosed in the world and more than 120,000 deaths associated with the disease have been reported.
Health effects
The OMS points out that skin cancers are caused, fundamentally, by exposure to ultraviolet radiation (UVR), either from the sun or from artificial sources such as tanning beds. Recommends the use of sunscreen when the ultraviolet index is 3 or higher.
“Some exposure to UV rays is beneficial for health, particularly for vitamin D. However, excessive sun exposure in children and adolescents contributes to breast cancer.” fur in old age,” says the WHO.
The organization also asserts that unprotected exposure to solar ultraviolet radiation at work is one of the leading causes of occupational skin cancer. At this point, he states that “there are effective solutions to protect workers from the sun’s harmful rays and prevent their lethal effects.”
UV rays can damage DNA, produce sunburn, phototoxic and photoallergic reactions, as well as suppression of the immune system. In this sense, immunosuppression can be considered a risk factor for cancer and cause virus reactivation, as occurs with cold sores.
