Tobacco use is one of the biggest public health threats the world has ever faced.There are over 4,000 chemicals in a cigarette,40 of which are carcinogenic.Nicotine,tar,HCN,volatile aldehydes,and nitrosamines are some of the hazardous substances in tobacco smoke.The most effective preventive measure is to avoid use.Cancer killed 5,56,400 people in the country last year and it is alarming that India has more than 300 million smokers.Five million of them are children and at least 55,000 children take to tobacco every year.
Oral cancer
There are twice as many deaths as a result of oral cancerthanks to tobacco chewingcompared to lung cancer.Rural men are twice more likely to die from tobaccorelated cancers,compared to urban men in India.The top five or six cancers in men are all tobacco-related : that of the lung,oral cavity,larynx,oesophagus and pharynx.In women,types of cancer that occur due to tobacco use are cancers of the cervix,oral cavity,oesophagus and lung.Combining alcohol with cigarettes increases risk of oral cancer,and of cancer of the larynx and oesophagus.Tobacco products produce changes in all of the cells that are exposed.Thus,the entire oral cavity,lungs and larynx are at risk for developing tumours.This can be prevented by simple changes in lifestyle and regular screening.
