There are heaps of reasons not to smoke cigarettes and here is another …
We can now precisely count how many cancer-related DNA mutations accumulate in smokers’ organs over time.
On average, there is one DNA mutation per lung cell for every 50 cigarettes smoked, according to a new analysis. People who smoke a pack of 20 a day for a year generate 150 mutations per lung cell, 97 per larynx cell, 39 per pharynx cell, 18 per bladder cell and six per liver cell.
Studies have previously linked tobacco smoking with at least 17 classes of cancer, but this is the first time researchers have been able to quantify the molecular damage inflicted on DNA.
The team hopes their findings will deter people from taking up smoking and debunk the myth that social smoking is harmless. Every cigarette has the potential to cause genetic mutations!
