Snoring increases risks of cancer

Studies have found that snoring is not just a sign for poor health, but it also increases the risk of cancer by five-fold as it, and other types under the category of 'sleep disordered breathing' (SDB), can deprive the body of the right amount of oxygen it needs for hours at a time.
A research regarding sleep problems conducted in the US to look at cancer rates in more than 1,500 people has been going on for 22 years. Statistics show that those with severe SDB were 4.8 times more likely to develop cancer rather than those who had no related problems.
According to the group from the University of Winconsin-Madison, those with moderate SDB had a double risk of cancer while those with a slight problem had a 10 per cent increased chance.
The most common type of SDB is obstructive sleep apnoea, which is known to be related to other health problems like obesity, diabetes, high blood pressure, heart attacks, strokes, etc.
Sleep apnoea is where the airway often collapses during respiration, leaving the sleeper struggling for air and produces snoring and forced waking.
However, there were other factors that one had to take in account whether participants were healthy or not such as age, sex, and smoking status. Even after everything was taken into consideration, the connection between SDB and cancer had a truth to it and it was proven to have a stronger effect for those who were at their healthy weight than those suffering from obesity.
Another study was conducted to confirm these findings. Leader of the study Dr. Javier Nieto used mice as samples to figure out the exact the association between SDB and an elevated risk of cancer. Results show that intermittent hypoxia (low oxygen levels) promotes tumor growth with skin cancer due to angiogenesis, a process where the lack of oxygen stimulates the generation of blood vessels that feed tumors.
Though the relationship between SDB and cancer risks was firmly established, further research is needed to affirm the connection between SDB and cancer risks, according to Dr. Nieto.
