Cancer caused is as a result of the tobacco
One of the main causes of cancer which can be commonly found in every environment is the smoking of tobacco, food diet, and obesity, strenuous activities, lack of exercises and air pollutions. Although this has always been a debated fact because the different causes of environmental cancer do not have a solid proof. One instance is given that, when a person smokes heavily develops lung cancer, cancer caused is as a result of the tobacco he/she had taken. But when a person who smokes less or doesn't smoke at all develop lung cancer, it has little to do with environmental factors.
A foremost causation of cancer is the use of tobacco. Scientists estimate that about one in three of cancer caused death around the world was facilitated by the use of tobacco. Tobacco contains nicotine and carcinogens which is one of the leading causes for the development of cancerous cells in the body. It has been proven that tobacco causes cancer to the lungs, but it has also been recorded that even the kidney, bladder, the liver, the larynx, head, neck, stomach, esophagus, pancreas and other body parts are at risk of cancer caused by tobacco in the body.
Another environmental causing agent of cancer is alcoholic consumption. In western Europe, research made have proven that an estimated 10 percent of males who drink alcohol and a 3 percent of women who drink, is at risk of getting cancer, especially in the body parts of the liver and the gastric areas.
