Smoking increases the risk of cancer of the colon and rectum

A medical study warned smokers that they are more susceptible to colon cancer as well as the risk of dying from this cancer.
The study, conducted by Italian researchers published their findings in the latest issue of the Journal of the American Medical Association that tobacco smoking increases the risk of developing colon cancer by 18%, and increases the risk of death from the malignancy rate of 25%, compared to non-smokers.
According to the study's lead author Eduardo Puteri biometrician and his colleagues in the department of epidemiology and biostatistics at the European Institute of Oncology in Milan, Italy, the statistical analysis shows a significant association between smoking and injuries and deaths from cancer of the colon and rectum.
Smoking is not restricted to the lungs: The study emphasizes the importance of public awareness that smoking increases the risk of cancer, not only in organs directly related to Bemsrtnat tobacco such as lung, pharynx, larynx and upper digestive tract, but also in organs exposed indirectly to the degradation products of tobacco, Kalpnkerias, kidney, bladder, cervix, colon and rectum.
Remember, the statistics contained in the study that tobacco is responsible for about 100 million deaths over the past century, more than five million deaths annually. However, the study indicates that there is still a billion smokers in different parts of the world.
The Puteri and his colleagues analyzed data from 106 studies to monitor and follow-up to previous studies, ranging from small trials, which include several hundred participants only, and surveys and very large trials with more than million participants.
When the researchers looked at the overall framework of pooled risk, they found that smoking was associated with an increase of 18% in the risk of cancer of the colon and rectum.
The researchers add that they found a positive correlation between increased risk of this cancer and the increase in the number of cigarettes and cans consumed per day, multiplied by the number of cigarettes consumed per day in a number of years of smoking.
