Image source: Keystone-SDA/Shutterstock, DNA repair genes could be keeping some smokers from getting lung cancer. Researchers found an inherent advantage in many smokers that never developed lung cancer. They found that the cells lining the lungs were less likely to mutate over time.
The researchers looked at the genetic profiles of 33 participants’ bronchial basal cells. All the participants were aged between 11 and 86 years old. 14 participants had never smoked, while the other 19 had varying histories of being light, moderate, and heavy smokers. That’s because their DNA is able to repair the body before the cell mutations develop into tumors. These DNA repair genes can be inherited or acquired, scientists say. And exactly what makes one person’s body better at repairing DNA is still a mystery.
Quite an unexpected finding, not to be embraced, as it is a random genetic property. iquitsmokingcig JohnLukeNYC Flamisharon DoctaDoMore MatopeNigell Chef_Tkay
