Angeline Jolie’s brave decision to have both breasts removed based on the genetic study showing there was an 87% chance she would develop breast cancer is making women everywhere look at their odds of getting breast cancer. Long term studies show American women have a 12 % chance of getting breast cancer during their lifetime (1).
Among the things that can be changed to improve these odds are giving up alcohol (more than a drink a day) smoking, and avoiding becoming obese. Choice of diet seems not to make much difference despite all the claims (2). Another thing that can be changed to reduce the odds of having breat cancer is one many people have never heard about before. It is the exposure to light at night, especially blue light. Nighttime exposure to light cuts off the production of melatonin. Melatonin is the sleep hormone but also fights cancer in about five different ways.
Numerous studies in both animals and humans dating back to the 1990s have shown that exposure to light at night increased the risk of developing breast cancer by about a factor of two (3). But women do not need to give up the use of night at night. According to Richard Hansler PhD, Director of the Lighting Innovations Institute at John Carroll University (JCU), the blue wavelengths in ordinary white light have been demonstrated to cause the problem. Light bulbs that don’t make blue light and glasses that eliminate it were developed at JCU in 2005 and are available from Photonic Developments LLC at http://www.lowbluelights.com. Using these products is the equivalent of being in darkness and thus might reduce the probability of having breast cancer.
Thousands of people have bought these products with the guarantee of money back if they don’t help them sleep better. About 90% find their sleep improved. Reducing the risk of breast and other cancers may be a free extra benefit.
Dr. Hansler is the author of “Great Sleep! Reduced Cancer!” and Heroes of Cancer Prevention Research” available from Amazon as paperback or Kindle books.
