Sunlight reduces the risk of esophageal cancer

Pressemeldung der Firma Sunlight Research Forum

Exposure to sunlight and UV is generally considered to be a risk factor for most forms of cancer, especially skin cancer. However a new study by Australian scientists shows that this general assumption is in fact unfounded.

The successful treatment and cure of esophageal cancer depends on several factors. These include the type of cancer, its stage of development and the age and general health of the patient. Esophageal cancer is often detected at a late stage of advancement, after it has already spread to the lymph nodes or attacked other organs. Once it has reached the advanced stage, the patient’s chances of recovery are a mere 20% and life expectancy is on average 5 years.

Scientists at the Queensland Institute of Medical Research, Brisbane, Australia, led by Dr. Bich Tran, realised that very little research has been done into the link between esophageal cancer and UV rays in sunlight. In their study, they investigated the connection between moles, freckles and environmental exposure to sunlight and UV over a lifetime to the risk of contracting esophageal cancer.

For the purposes of the study, the researchers compared the estimated lifelong UV dose of almost 1,000 esophageal cancer sufferers with a control group of 1,500 persons. They discovered an inverse relationship between the amount of sunlight/UV exposure a person receives during their lifetime in the area where they live and the risk of contracting esophageal cancer. It is also interesting to note that the study was carried out in Australia. This is a country where increased UV exposure as a result of the hole in the ozone layer is considered extremely dangerous for human health.

However the study shows that the bad reputation of UV light – whether from natural sunlight or sunbeds – is often unjustified. „UV exposure from sunlight and sunbeds has many positive effects on human health. We recommend moderate exposure, as this is proven to increase vitamin D levels“, Ad Brand of the Sunlight Research Forum (SRF) explains.

The Sunlight Research Forum (SRF) is a not-for-profit organisation based in The Netherlands. SRF's aim is to help bring to the fore, the latest medical and scientific information on the effects of moderate UV exposure on man. It takes time, often decades, for new scientific ideas to be accepted and assimilated, first into the general body of scientific knowledge and finally into policy. We want to reduce this time to a minimum so that the benefits of research can lead to a better understanding of UV effects on man and will become available to the public without any unnecessary delay. We hope to provide policy makers with correct information on which to base national health policy and individuals with better information on which to base choices about their lifestyles. New research and well founded ideas on moderate UV exposure both indoor and outdoor will be presented and discussed in the Sunlight Research Forum by people working in the health disciplines, by academics and by journalists.
