Causes of Cancer
The World Health Organization reported that cancer, a leading cause of death worldwide, accounted for 8.2 million deaths in 2012.
Several factors are known to cause to cancer in certain parts of the body. For example, tobacco use can cause cancer of the lung, mouth, tongue, and throat. Other factors which are considered to be able to cause cancer or render an individual more prone to get cancer include:
- Chemicals and materials used in building and manufacturing (ex. asbestos, benzene)
- High fat or low fiber diets
- Air and water pollution
- Lack of physical activity
- Alcohol abuse
- Certain viruses
A lot of people that are exposed to these factors do not get cancer – sadly, some do.
