Sleep Apnea Sleeping Disorders Linked To Cancer


A some what surprising revelation has recently been announced and will have huge implications on people suffering from Sleep Apnea and extreme Snoring Disorders.

Sleeping disorders like Sleep Apnea have been directly linked to Cancer.

A long term study has been release by the University of Wisconsin School of Medicine and Public Health on the 20th May 2012. The study shows that people suffering from sleep apnea appear have an increased risk of cancer mortality.

Well known studies in the past have linked the Sleep Disordered Breathing (SDB) problems to cardiovascular disease, hypertension, depression and even earlier death, however this is the very first study to find a link to cancer.

These extensive findings have been based on data collected from sleep studies carried out on 1,522 people over 22 years. In the past lab tests on mice showed that oxygen starvation, caused by snoring promoted cancerous tumor growth.

The studies lead author Dr F. Javier Nieto, Chairman of the Department of Population Health Sciences located at the University of Wisconsin School of Medicine and Public Health said:

“The consistency of the evidence from the animal experiments and this new evidence in humans is highly compelling.”

“Ours is the first study to show an association between Sleep Disordered Breathing (SDB) and an elevated risk of cancer mortality in a population-based sample,” said Nieto, reports the American Journal of Respiratory and Critical Care Medicine.

“If the relationship between SDB and cancer mortality is validated in further studies, the diagnosis and treatment of  SDB in patients with cancer might be indicated to prolong survival,” added Nieto, according to the Daily Mail.

These new discoveries were presented on the 20th May during the American Thoracic Society international conference conducted in San Francisco.

It was further revealed that mild snorers have a negligible risk of dying from cancer but in moderate snorers the risks double and then escalates dramatically to almost five times for those people who are severe snorers. People who suffer from sleep apnea are within this range.

We already know from extensive research that people with sleep apnea have an increased risk of heart attack, stroke and diabetes. This new study now finds them up to five times more likely to die from cancer than those without. The same study also found that people who were not obese were more susceptible.

“This is just another bit of evidence that says not breathing is bad for your health,” said Dr. Eric Hernandez, who explained that the negative health effects are caused by oxygen levels in the blood.

When people who suffer from sleep apnea stop breathing multiple times during the night, including for seconds or minutes at a time, blood vessels begin to grow into the tissues that suffer from a lack of oxygen to help battle the disease.

“If someones oxygen drops, it means additional blood vessels grow and if blood vessels grow into tumors, tumors grow faster,” explained Dr Eric Hernandez.

Dr. Nieto’s team located at the University of Wisconsin-Madison completed the research in collaboration with Dr. Ramon Farré, professor of physiology at University of Barcelona, Spain.

Dr. Farre’s team also demonstrated that intermittent hypoxia on cancer growth is significantly stronger in lean mice than in obese mice.

About 28 million Americans have some form of sleep apnea, and it is well known many cases go undiagnosed.

Will ZQuiet Cure Sleep Apnea

ZQuiet does not suggest in any way that their mouthpiece can be used to cure Sleep Apnea. ZQuiet can assist people suffering from “Simple Snoring” problems.

The study mentioned above does however, link people who snore severely, with cancer. You could certainly draw an assumption that if you are a heavy snorer then their is some concern.

My Conclusions/Recommendations

The main things I picked up on from the article was:

1. Mild snorers have a negligible risk of dying from cancer, but doubles in moderate cases and increases significantly up to nearly five times in case of severe snoring.

2. You don’t have to be obese to be in the high risk cancer link category. In fact lighter people who suffer from sleep apnea or severe snoring are more prone to the cancer link.

I am not a huge person nor am I a heavy snorer but I chose to use ZQuiet to control those horrible noises. Even if if you don’t think ZQuiet is for you, I would strongly suggest you find something to combat your snoring problem.
