Snoring ‘can raise cancer risk five-fold’, according to scientists. Low blood oxygen levels seen in some snorers may encourage the growth of tumors, and that STOPPING SNORING could help people fight cancer.
Sleep disordered breathing (SDB) is a term that describes a group of disorders characterized by abnormalities of respiratory pattern (pauses in breathing).This is due to complete or partial obstruction of breathing.
The researchers found that participants with severe sleep-disordered breathing showed a significantly higher risk of dying of cancer than those with normal sleep breathing. People with less severe sleep-disordered breathing had no significantly increased risk of dying of cancer.
Snoring and other types of ‘sleep disordered breathing’, can deprive the body of enough oxygen for hours at a time.
Scientists now believe having low blood oxygen levels can trigger the development of cancerous tumors, by promoting the growth of the vessels that feed them. By far the most common type of sleep disordered breathing problem is obstructive sleep apnea. In this, the airway frequently collapses during the breathing cycle, resulting in multiple brief episodes of cessation of breathing. Typically this produces snoring and repeated forced awakenings. Symptoms of sleep apnea include extremely loud snoring, excessive daytime sleepiness and morning headaches.
Laboratory studies have also shown that intermittent hypoxia – or low oxygen levels – promotes tumour growth in mice with skin cancer. Lack of oxygen stimulates the generation of blood vessels that nourish tumours.
If the relationship was established, the diagnosis and treatment of SDB in patients with cancer might be indicated to prolong survival.
