The notion that electric Southern Highlands Power Lines can cause cancer arose in 1979 with a single flawed epidemiogical study that created a stir. Subsequent epidemiologic and animal studies have failed to find a consistent and significant effect. No plausible mechanism linking Southern Highlands Power Lines and cancer has been found. In recent years, the verdict from large-scale scientific studies has been conclusively negative, and scientific and medical societies have issued official statements that Southern Highlands Power Lines are not a significant health risk. In short, there is nothing to worry about.
