It "can" lead to .....? It can?? So does it or doesn't it? Or is it only a possibility?
Tobacco smoke contains a powerful carcinogen called benzo(a)pyrene (BAP), which, when metabolized by the body, produces a highly mutagenic substance
called benzo(a)pyrene diol epoxide (BPDE). The scientists have found that BPDE when introduced to human lung cells quickly binds chemically to the P53
gene resulting in its function being compromised. It produces the same P53 gene mutation that are common in lung cancer. So in answer to your
question, yes, it does lead to lung cancer.
Whether one falls prey to lung cancer eventually depends, as I mentioned before, upon the strength of your immune system and whether it is capable of
repairing damaged DNA caused by cigarette smoking. Some people are blessed with strong genes, so they may go through life smoking away and not get
cancer. Others may not be so lucky, and will succumb to it at a time when their immune system is suppressed or compromised.
I guess this applies to most cancers, but smoking definitely does not help.
Benzo (a) pyrene is found in all smoke including the smoke from grilling meat, burning candles, burning wood, BBQ, its in vehicle exhaust, diesel
exhaust etc etc etc
Cigarette smoking is an addiction. Unless you are addicted to sniffing smoke from grilling meat, candles, vehicle exhaust or chimney daily, this
argument is pointless.
Primary question: Since benzo (a) pyrene is a by-product of combustion and man has been surrounded by such products since the dawn of time -
how is it that the lung cancer rate is still rising
Tobacco consumption is still on the rise in the developing world, although the rate is falling in developed nations. To exclude air pollution to the
rising cancer stats, would be equally deceiving. However, cigarette smoking is liken to adding fuel to fire.
Among young teens (aged 13 to 15), about one in five smokes worldwide. Between 80,000 and 100,000 children worldwide start smoking every day - roughly
half of whom live in Asia.
This is where the tobacco industry find it new recruits
Finland has a history of monitoring its tobacco smoking and lung cancer incidences with great diligence. From the statistics gathered, the study show
that there is dramatically strong evidence between smoking prevalence and the lung cancer and respiratory diseases rates. The correlation applies to
both gender but more pronounced in men due to the large reduction in male smoking prevalence.
Defend the tobacco industry as much as you like, it is you who are taking all the risks. With all the hazards of modern living like pollution,
pesticides, food additives, etc. do you really need another poison to the list. That is not even considering burning good money away.
