British Medical Journal: Passive smoking has a 51% risk of oral cancer

A study published in the British Medical Journal revealed the risks facing people who are exposed to secondhand smoke, as it was found that they are 51% more likely to develop oral cancer, according to a report on the Medical Express website.

The researchers said that oral cancers, which include cancer of the lip, oral cavity and pharynx, affect about 447,751 cases annually, while the resulting death rates are 228,389 deaths each year worldwide.


The study indicated that important risk factors for these forms of cancer include smoking and inhaling tobacco for those who do not smoke in the first place, and alcohol consumption, as tobacco smoke constitutes the largest exposure to humans to carcinogenic chemicals, and causes one in five deaths related to cancer in the world.

The researchers emphasized that smokers are not the only ones at risk of developing oral cancer, according to data from 192 countries, which expose 33% of non-smoking males, 35% of non-smoking females, and 40% of children to passive smoking within one year by inhaling second-hand tobacco. Those who were exposed to secondhand smoke were 51% more likely to develop oral cancer.


The study showed that inhaling secondhand smoke causes many diseases, including lung cancer, although tobacco smoking is a known cause of oral cancer, and it was found that when exposed for more than 10 or 15 years to secondhand smoke, this increases the risk of oral cancer for more than Twice as compared to unexposed individuals.


The study recommended the necessity of determining the harmful effects of exposure to secondhand smoke, along with the necessity of presenting effective programs to prevent exposure to secondhand smoke.
