Melanoma
Risk Factors
- The main risk factor for melanoma is sun exposure. Especially sunscreens protect against UVB rays (those that cause burns) and less UVA radiation. Although UVA and UVB radiation affects the skin differently, they both can cause skin changes that can lead to cancer. Also, radiation from tanning equipment can be harmful to the skin.
Other risk factors or warning signs for melanoma are:
- a mole that changes its appearance (the main clinical sign of alarm)
- atypical or dysplastic nevi
- number of common nevi (> 100)
- giant congenital nevus (> 20 cm in diameter in an adult)
- history of melanoma
- Sensitivity to sun / sunburn history of
- Cases of melanoma in family (1st degree relatives)
- a history of basal cell carcinoma or squamous cell carcinoma
- age over 50 years
- xeroderma pigmentosum - rare, hereditary, characterized by the appearance of pigmentation spots on exposed areas, which evolves into multiple squamous responsible for death during adolescence
