Studies have shown that quitting smoking at any stage can save a smoker’s life. Even if it doesn’t, your life could be prolonged because you have stopped smoking.
Doctors in England said that smokers diagnosed with lung cancer should not assume they have a death sentence. Quitting smoking even if you are diagnosed with a fatal illness can greatly boost your chances of survival.
63 to 70 percent of smokers who quit after diagnosis were still alive after five years. This 5-year period is a benchmark of survival in cancer research. On the other hand, only 29 to 33 per cent of smokers who continued to smoke survived this 5-year period, said an online report published by the British Medical Journal.
The study was a result of a review of 10 published studies in smoking and cancer survival carried out by scientists at Birmingham University, central England.
The authors speculated that tobacco smoke may accelerate progression of a tumor, although further work is needed to confirm this.
In spite of the lack of empirical evidence, the study showed it could be worthwhile for doctors to encourage smokers to give up their habit when diagnosed with early-stage lung cancer.
The connection between smoking and lung cancer has been know for many years. The risk of developing a primary lung tumor is 20 times greater for a hardcore smoker than a non-smoker, according to a 2003 study.
So smokers, stub it out while you still can!
