Tobacco use is centuries old. The two main forms of tobacco use are chewing and smoking. India, in particular, is the second largest consumer and third largest producer of tobacco in the world. The prevalence of overall tobacco use amongst the males is 48% and among females is 20%.
Cigarette smoking is probably the largest factor to the large burden of cancer in our society. Smoking does not only increase the chances of a person developing lung cancer, but also bowel, stomach, pancreas, head and neck cancers. More than 4000 different kinds of chemicals have been found in tobacco and tobacco smoke. Over 60 of these chemicals have been classified as carcinogens by IARC. The main chemical found is tobacco is nicotine which is a highly addictive chemical. The usage over a long period makes a person physically and psychologically dependent on it..
Tobacco use affects almost all the major organs and system in the body causing a great deal of pain and untimely death. The use in any form can cause cancer in different organs/sites in the body such as mouth, throat, larynx, brain, oesophagus, lungs, gall bladder, kidney and breast. Tobacco also causes many disorders such as heart diseases, stroke, blindness, teeth and gum diseases. Nearly 45% of all cancer among males and 17% among females in India and more than 80% of oral cancers are directly attributable to tobacco use.
This is nothing new. The best cancer clinic have told us this about the harmful effects since decades, despite all the efforts and achievements in fighting the tobacco epidemic from different sectors of the society. Efforts to decrease the number of smokers have been focused on the youth. The number of smokers among the adults aged 65 years and older has meanwhile grown, possibly because older adults may be unaware of the benefits of termination. There is enough evidence about the harms of smoking and the benefits of quitting.
Hence, the best cancer clinic say that a renewed focus on nicotine can help us to achieve a world with lessened or no use of tobacco.
