  • Introduction: The ozone layer, a natural shield, effectively absorbs the majority of the sun’s ultraviolet radiation. However, with the advent of industrialization in various nations towards the end of the 20th century, the degradation of this protective layer has commenced, leading to an escalation in the proportion of UV-B rays reaching the Earth’s surface. A recent study has further revealed that a long-term temperature increase of two degrees Celsius, a consequence of global warming and climate change, amplifies the carcinogenic effects of solar UV by 10%. Prolonged exposure to sunlight has been implicated in the incidence of other skin cancers such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and other skin malignancies. This research paper delves into the factors contributing to the prevalence of melanoma in Iran and explores commonly employed treatment strategies.
  • Methods: The essay focuses on melanoma, providing information about its origin, subtypes, and statistics; furthermore, it presents information in a clear and organized manner, using citations to support its claims.
  • Results: 1. There is a significant correlation between prolonged and frequent exposure to UV rays and the prevalence of skin cancers, especially in areas of the body that are often exposed to sunlight such as the face, neck, and hands. 2. The increase in melanoma cases in Iran can be attributed to various climatic and non-climatic factors. These include the depletion of the ozone layer, global warming, and increased exposure to sunlight due to outdoor activities. 3. The high costs associated with cancer treatment in Iran, coupled with limitations in selecting effective treatment methods for melanoma, highlight the urgent need for increased public awareness about the necessary precautions against harmful sun rays. 4. Enhancing public knowledge about the potential consequences of long-term exposure to ultraviolet rays is crucial and should not be overlooked.
  • Conclusion: Skin cancers, particularly prevalent in sun-exposed areas like the face, neck, and hands, highlight the link between UV exposure and skin cancer. Melanoma cases in Iran have increased due to factors like ozone layer depletion, global warming, and outdoor activities increasing sunlight exposure. The high costs and limitations of cancer treatment in Iran necessitate public awareness campaigns about sun protection. Additionally, educating the public about the risks of long-term UV exposure is crucial.
