Appropriate sun-protective clothing, use of broad-spectrum (UVA/UVB) sunscreen with at least SPF 50, and avoidance of intense sun exposure may prevent skin cancer. [50] A 2016 review of sunscreen for preventing cutaneous squamous-cell carcinoma found insufficient evidence to demonstrate whether it was effective. [51]
Dermatophagia. Dermatophagia (from Ancient Greek δέρμα — lit. skin and φαγεία lit. eating) or dermatodaxia (from δήξις, lit. biting) [3] is a compulsion disorder of gnawing or biting one's own skin, most commonly at the fingers. This action can either be conscious or unconscious [4] and it is considered to be a type of pica.
A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation . The most common type of radiation burn is a sunburn caused by UV radiation.
Skin cancer is the most common form of cancer, globally accounting for at least 40% of cancer cases. [5] [20] The most common type is nonmelanoma skin cancer, which occurs in at least 2–3 million people per year. [6] [21] This is a rough estimate; good statistics are not kept. [1]
Excessive unprotected exposure to the sun's ultraviolet (UV) rays can cause skin damage, eye damage, immune suppression, and skin cancer. Even people in their 20s can develop skin cancer.
Too much UV ultraviolet radiation of an undesirable wavelength may lead to direct DNA damage, sunburn, and skin cancer. [6] In contrast to exposure to UV-B light given at low dosage, it was found that UV-A light increases the risk of skin cancer because it penetrates the epidermis and it is given in a much higher dosage.
Researchers have demonstrated that CBD may have potential protective benefits against UVA radiation, the type of wavelength that can cause aging and lead to cancer. A small study of just 19 ...
PUVA ( psoralen and UVA) is an ultraviolet light therapy treatment for skin diseases: vitiligo, eczema, psoriasis, graft-versus-host disease, mycosis fungoides, large plaque parapsoriasis, and cutaneous T-cell lymphoma, using the sensitizing effects of the drug psoralen.
