Chewing Tobacco Ups Stroke, Cancer Risk, Study Shows – Chewing tobacco has been found to be significantly associated with higher risks of stroke and several types of cancer. A study conducted by researchers analyzed the relationship between chewing tobacco and health outcomes, including stroke, ischemic heart disease, and various cancers of the head and neck. The study, which included data from publications dating back to 1970, found that chewing tobacco is linked to an increased risk of stroke and various types of cancer, such as lip, oral cavity, esophageal, nasopharyngeal, and laryngeal cancer. The research highlighted the need for more high-quality studies on the associations between chewing tobacco and other types of cancer. Additionally, the study emphasized the health risks associated with chewing tobacco, particularly in regions where its popularity, including among women, has increased. The findings underscore the critical health implications of chewing tobacco and the need for public intervention to address its associated risks.
The American Cancer Society also emphasizes that smokeless tobacco, including chewing tobacco, exposes users to more than 25 chemicals known to cause cancer, and it is associated with an increased risk of dying from heart disease and stroke.
Therefore, the evidence from the study and the American Cancer Society underscores the serious health risks linked to chewing tobacco, including elevated risks of stroke and various types of cancer.
Key Findings:
- Chewing tobacco users face a 16% increased risk of stroke compared to non-users.
- The study found weak evidence linking chewing tobacco to increased risk of other health issues, including ischemic heart disease and certain cancers.
- Stronger evidence suggests a significant 2% increase in esophageal cancer risk and a 3.64-fold increase in lip and oral cavity cancers linked to chewing tobacco.
How does chewing tobacco affect the body differently than smoking
Chewing tobacco affects the body differently than smoking. According to a study published in Nature, chewing tobacco is weakly to moderately associated with an increased risk of stroke, as well as with various cancers such as lip, oral cavity, esophageal, nasopharyngeal, and laryngeal cancer.
On the other hand, the Centers for Disease Control and Prevention (CDC) states that smokeless tobacco, including chewing tobacco, is associated with health problems such as nicotine addiction, cancer of the mouth, esophagus, and pancreas, and diseases of the mouth. Therefore, chewing tobacco and smoking have distinct health effects, with chewing tobacco being specifically linked to an increased risk of certain cancers and stroke, as well as other health problems associated with smokeless tobacco use.
Study Implications
These findings underscore the dangers of chewing tobacco, even though it’s not as prevalent as smoking.
Public health initiatives and awareness campaigns should highlight the risks associated with chewing tobacco.
More research is needed to understand the full scope of health risks associated with different types of chewing tobacco and specific cancers.
