American Association For Cancer ResearchIt is widely known that smoking could increase the risk of contracting lung cancer. But not many know that smoking may also augment the danger of developing colorectal cancer too. At least this is what a study claims.

The outcome of a new study apparently reinforces the proof that smokers who have taken the puff for quite some time could have a bigger danger of suffering from colorectal cancer, even post adjusting other risk issues.

“This provides one more reason not to smoke, or to quit as soon as possible. Colorectal cancer should be added to the list of cancers caused by smoking,” commented, senior author Michael J. Thun, M.D., M.S., vice president emeritus, epidemiology and surveillance research at the American Cancer Society.

Thun and colleagues apparently examined the link between long-standing cigarette smoking and colorectal cancer post altering several other factors that are usually connected to risk, counting screening. From 1992 to 2005, the experts trailed nearly 1,85,000 subjects who were between 50 to 74 years old. The participants illustrated their behaviors and medical conditions.

The subjects who smoked cigarettes for around 40 or more years, or who did not abstain from smoking prior to age 40, apparently had a 30 to 50 percent augmented danger of contracting colon or rectal cancer during the follow-up, even in examination that supposedly regulated for 13 other likely threat issues. Following 13 years of follow-up, the experts have apparently recognized around 1,962 cases of invasive colorectal cancer.

Preceding big studies performed in lasting smokers supposedly exhibited comparable outcomes. Thun is of the opinion that this is the first study to manage the screening and all of the assumed risk factors for colorectal cancer like alcohol consumption, physical immobility and eating red or processed meat.

The findings of the study are published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
