LONDON – People with early lung cancer who quit smoking could double their chances of surviving, a new study says.
Until now, there has been little proof that quitting smoking after developing lung cancer makes any difference to survival.
British researchers analyzed previous data from 10 studies examining how long smokers survived after being diagnosed with lung cancer.
People with lung cancer who continued smoking had a 29 to 33 per cent chance of surviving five years. But those who kicked the habit had a 63 to 70 per cent chance of being alive after five years. The research was published in the BMJ, formerly known as the British Medical Journal.
