It has been revealed that, more than 80 substances that is present in tobacco smoke has the potential to give rise to a cancer and out of which lung cancers, cancers of the head and neck, bladder cancers, cancers of the kidneys and cervix as well as bowel and pancreatic cancers would be featured prominently.
Furthermore, it is estimated that, there are about 438,000 smoking related deaths in the United States each year and more alarmingly, not only direct smokers, but about 38,000 people who are secondary or passive smokers will also die each year from smoke related complications including cancer.
Lung cancer being the commonest cancer among adults, 80% of deaths related to this disorder is related to smoking and its hazardous effects. As such, it would be vital to know some details about the types of cancers that tobacco can cause along with what type of disease burden that it causes among the human society which exactly is what this article is going to talk about.
Lung cancers are the commonest cancer among adults in the US and many parts of the world and also is the leading cause of death among cancers as well. Its prognosis is rather bleak and a persons risk of developing lung cancer can be increased by 5 – 10 folds if that person smoke.
Not only direct smokers, but also the passive smokers are at risk of developing the same at a higher risk than people whom have not been exposed to tobacco smoking at all.
Cancers of the head and neck
It is also been researched and concluded that, certain cancers in the head and neck area such as, oral cancers, cancers of the larynx and pharynx are also in the rise among the smokers.
Direct exposure to inhaled toxic substances in the tobacco smoke as well as being subjected to absorbed elements to the blood stream would be the culprit in giving rise to such higher risk among these people.
According to statistics, men who smoke will have a 27 times more risk of developing oral cancers and 12 times more risk in developing laryngeal cancer than the ones who do not smoke.
The presence of polyaromatic hydrocarbon in the cigarette smoke has been postulated to be the cause for the development of bladder and kidney cancers. It is estimated that among these patients, about 40 – 70 % are related to tobacco smoking and is considered to be the single most risk factor for developing bladder cancer among adults of the developed countries.
Other than the above cancer types, smoking seems to increase the risk of developing cervical cancer in women by 1.6 folds and also accounts for 30% of pancreatic cancers as well.
In conclusion, it is evident that tobacco causes a detrimental effect to our health and it should be stressed that, reducing or stopping smoking altogether reduces these risk levels to exponentially low levels along with other diseases related to tobacco smoking.
