Skin cancer and ultraviolet‐B radiation under the Antarctic ozone hole: southern Chile, 1987–2000

Abstract

Highly unusual ozone loss and UV-B increases have occurred in the Punta Arenas area over the past two decades resulting in the non-photoadapted population being repeatedly exposed to an altered solar UV spectrum with a greater effectiveness for erythema and photocarcinogenesis. This phenomenon has not previously been reported over other populated areas and an additional increase in the skin cancer rate attributable to the AOH may be occurring. Research on the clinical and subclinical impact of these abnormalities is urgently needed.

Changing Trends of Types of Skin Cancer in Iran

“…Other studies also confirmed our results (Stang et al, 2006;Hussain et al, 2010). Increasing global incidence of skin cancer may be due to several factors, including climate change, environmental factors, an increase of public awareness, and diagnostic advances that have occurred in the years (Abarca and Casiccia, 2002;McCarthy, 2004;Bulliard et al, 2006;Ibiebele et al, 2007).…”

Solar cheilosis: An ominous precursor

“…SC has high prevalence rates in countries near the equator, particularly in populations with high-risk occupations. 33,61,66,67 Studies have also shown an increased incidence of lip SCC in those populations, lending further credence to UV damage as the major etiologic agent. 66 There is a greater incidence of SC and lip SCC in men, with a 3:1 incidence ratio.…”

Trends of skin cancer incidence in 6 geographical regions of the Islamic Republic of Iran, 2000-2005

“…However, despite the global increase in the incidence, the mortality rate from the condition has decreased, especially in the US and Europe [29]. Researchers consider higher rates of reported (due to higher awareness of the symptoms and early detection) [30], thinning of the ozone layer and thus higher exposure to ultraviolet light [12], changes in people's exposure to sunlight and bad sun protection habits [31] and diet changes towards higher intake of fat and meat [32] as the major underlying causes of the increased incidence of skin cancer.…”

“…For example in Queensland, Australia, the incidence is higher than in Europe and North America [2]. Although sunlight is an important risk factor, the development of skin cancer is mainly related to solar ultraviolet radiation [3,8,11], the dose of which are thought to be increasing as a result of thinning of the ozone layer of the atmosphere [12]. Among other risk factors are high alcohol consumption [13], diets high in fat and meat [14] and genetic predisposition [15].…”
