Smoking after Cancer Diagnosis Increases Death Risk: US Researchers
US researchers said that men who keep on smoking even after being identified with cancer have greater risk of death compared to people who give up smoking.
The latest study is published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research on Friday. The study illustrated it is not too late to quit smoking after cancer diagnosis, reported Xinhua.
The data used by the researchers was from a study exploring the link between daily life characteristics and danger of cancer among middle-aged and older men in Shanghai, China. From the year 1986 to 1989, more than 18,000 men belonging to an age group of 45 to 64 years were registered in the study.
They determined that over 1,600 contestants had developed cancer by 2010. Of these participants, 340 were non-smokers, 545 of them were those who quit smoking before the identification of cancer and 747 were smokers at the time of diagnosis.
Of the 747 smokers at diagnosis, 214 gave up smoking after diagnosis, 197 continued smoking constantly and the remaining 336 smoked occasionally.
Study author Li Tao, an epidemiologist at the Cancer Prevention Institute of California in Fremont, said, "Our study provides evidence of the impact of post diagnosis smoking on survival after cancer, and assists in addressing the critical issue of tobacco control in cancer survivorship".
