Smoking And Cancer
Smoking and Cancer, what a loaded word. To say we are not talking about shellfish, but about the disease. I think it is not necessary to remind once again about how smoking is dangerous to health. And yet, in my opinion, to use in this case is exactly the word ‘dangerous’, but not so nice trick – ‘harm’. Yes, of course, hurts, so much so that before his death. In addition to nicotine, tobacco, due to which there is a dependence, also contains carcinogenic substances, and they cause cancer.
Part of carcinogens found in tobacco directly, while others are produced by burning tobacco, and its treatment. Cancer can arise throughout the passage of smoke in the body, and not only that. More: if you follow this rule, first, the cancer must occur in the oral cavity. Yes, that’s right – it all starts with lip cancer, and further through the body. Can make to the list of victims stomach, liver, urinary bladder, kidney, esophagus, tongue, pancreas, larynx, cervix.
And, finally, bronchi and trachea. It seems all. Of course, cancer can occur in non-smokers, but the risk of its occurrence in smokers is much higher: 2-3.If you smoke more heroic one pack per day, the risk increases 10 times. Very high risk is lung cancer and larynx. And if you smoke more than 25 cigarettes per day, the risk increases by 3-4 times more. Age plays a big role, in which a person started smoking, the sooner, the higher the risk of deadly disease. Returning to the numbers: 5 times increased risk of esophageal cancer at 1.5 times – the stomach, B2-3 times – pancreas. Doctors say the link between cancer and smoking anus – not too pleasant, is not it? The risk of kidney cancer and bladder cancer increases by 5-6 times. Unfortunately, there is such a thing as passive smoking – only to find next to a man who smokes increases the risk of lung cancer by 30%.
