How Can Smoking Cause Cancer?



Smoking is the cause of most cancers can be prevented. because the holding of research over the years, it is now the increasingly clear link between smoking with cancer. Based on data from the American Cancer Society, nearly half (48.5%) death cases from 12 different types of cancers are caused by smoking.

The good news, many of these death cases can actually be prevented, simply by quitting smoking. You can get help doing it by following the tips to quit smoking.

What are the Cancer Types Caused by Smoking?

The chemicals in cigarette smoke enter our bloodstream and can affect the whole body. This is why smoking can cause cancer and many other diseases, including at least 14 types of cancer, heart disease, and various lung diseases.

Smoking causes more than 4 out of 5 cases of lung cancer. Lung cancer is the most successful type of treatment compared to other types of cancer and is the number one cause of death for men in the world.

Smoking also increases the risk of at least 13 other types of cancer, including cancer of the mouth, pharynx (the upper part of the throat), the nose and sinuses, larynx (voice box), esophagus (esophagus), liver, pancreas, stomach, kidney, stomach, colon, ovary, bladder urinary tract, cervix, and some types of leukemia (blood cancer). Smoking can also slightly increases the risk of breast cancer.

What Can Affect The Risk Of Cancer Due To Smoking?

Smokers have a much greater risk to suffer from lung cancer than non-smokers, no matter what type of cigarettes smoked him. There is no such thing as a safe way to smoke.

Smoking and smoking filter with low tar content gives only a little difference — a risk for lung cancer you will not become lower than that of smokers in General. This may be because smokers tend to change the way they smoke to satisfy their nicotine craving, for example with sucking
The more cigarettes you smoke each day, the greater you are a risk of cancer.

If you can not afford to stop smoking immediately, try to gradually reduce the number of cigarettes smoked each day. Even the occasional smoking can endanger your health, so keep trying to quit smoking from now on.

Researchers have found that the number of years you spend on smoking affects your risk of cancer. Even the effect on the level of risk is greater than the effect of the number of cigarettes you smoke each day. For example, smoking a pack every day for 40 years is far more dangerous than smoking 2 packs a day for 20 years.

The effects of smoking are very damaging cannot be restored even though You've been seeking a healthy lifestyle, such as keeping the body stay fit and healthy eating patterns, but still smoking. The only best way to lower the risk of cancer is to quit smoking forever.

How Can Smoking Cause Cancer?

The main way of smoking can cause cancer is to damage our DNA, including the major genes that are supposed to protect us from cancer. Many of the chemicals contained in cigarettes has proven to be capable of damaging DNA, including materials benzene, polonium-210, benzo (a) pyrene, and nitrosamines.

This is bad news, but that makes it even worse is the presence of deposits of other chemicals in cigarettes. For example, the content of chromium to make toxins such as benzo (a) pyrene can stick to more powerful on the DNA, so that zoom in on likely to inflict severe damage.

And chemicals such as arsenic and nickel interfere with the path of genes to repair damaged DNA. This further enables the cells that have been damaged to eventually turn into cancer cells.
Smokers also become less able to handle toxic chemicals than people with healthy lungs and blood. Chemicals in cigarette smoke make it difficult for them to neutralize or remove toxins and can make the immune system less effective.

How Long Does It Take Until Smoking Causes Cancer?

It normally takes years, or decades, to DNA damage due to smoking is a cause of cancer. Our body is designed with the ability to cope with little damage, but it's hard for the body to cope with a variety of dangerous chemicals from tobacco smoke.

Every cigarette can damage DNA in many lung cells, but damage to the same cells that have accumulated can cause cancer. But research has shown that for every 15 smoked cigarettes a DNA change can cause cells to turn cancerous. This is why people are strongly encouraged to quit smoking soon instead of waiting.

Can Passive Smokers Also Be At Risk For Cancer?

Inhaling the smoke from other people's cigarettes, called passive smoking, can also be a cause of cancer. Passive smoking increases the risk of non-smokers to suffer lung cancer until his quarter and could increase the risk of cancer of the larynx (voice box) and the pharynx (the upper part of the throat).

Passive smoking is especially dangerous for children. Children who inhale cigarette smoke are at great risk for suffering from respiratory infections, asthma, bacterial meningitis, and sudden infant death syndrome.

In children, most passive smoking occurred in their own homes. Smoke can spread throughout the home, even though the window is already opened. Almost 85 percent of Tobacco smoke is not visible and the particles smoke also accumulate on the surface of the surface and the garments, although the negative impacts of the remaining particles of smoke are still not examined. If you are a smoker, Have tolerated is by smoking outside so that the children do not breathe the smoke from the cigarettes you.

In addition to the house, passive smoking is also very likely to occur in the car. During the trip, children sitting in the backseat will inhale the smoke from parents' cigarettes. The level of pollution of cigarette smoke in particular so very high when all the windshield is closed.

Is Smoke From Other People's Cigarettes Containing Hazardous Chemicals? 

There are two types of tobacco smoke. First, the main smoke, which is directly sucked through the tip of the mouth of a cigarette. Second, smoke sidestream, which comes from the tip of a burned cigarette. The smoke from someone else's cigarette is the smoke of the sidestream and the main smoke puffed by the smoker, which mixes with the surrounding air.

Sidestream smoke is about 4 times more toxic than the main smoke, although people inhale it in non-concentrated forms. This is because the sidestream smoke contains much higher levels of toxic and cancer-causing chemicals, such as carbon monoxide at least 3 times as much, nitrosamines 10 to 30 times as much, and ammonia about 15 to 300 times as much.

Does Other Tobacco Types Also Cause Cancer?

As already mentioned, there is no safe way to use tobacco. Tobacco can be used in a variety of forms but they are all related to cancer.

Some forms of tobacco in addition to cigarettes for example :


  • Cigars and pipes are known to increase the risk of many cancers, including lung, mouth and upper throat, esophagus, larynx, and stomach. Smoking cigars and pipes are as dangerous as regular smoking. 


  • Rolled cigarettes contain as many cancer-causing chemicals as regular cigarettes. Rolled cigarettes are no safer than regular cigarettes.


  • Bidi cigarettes are a very common type of cigarette in the Indian community, also causing cancer just like other tobacco products, such as cigars.

Does Smokeless Tobacco Be Also Dangerous? 

Smokeless tobacco includes a wide range of products that can be used in different ways, for example, chewed (dry chewing tobacco), smoked (moist oral tobacco), or inhaled (nasal stuff). Researchers have shown that many forms of smokeless tobacco also increases the risk of cancer of the mouth, esophagus, and pancreatic cancer.

Most types of smokeless tobacco contain at least 28 different chemicals cause cancer. The users of smokeless tobacco can also be affected by a number of cancer-causing nitrosamines content as well as the same amount of nicotine, or higher, than the usual cigarette users. So in conclusion, using smokeless tobacco or smoking can cause cancer as well as highly addictive (causing the addicted).

Does Shisha Also Cause Cancer? 





Many people think that shisha is harmless, but actually, shisha also contains tobacco. Shisha smokers also called hookahs or water pipes, inhale deliberate tobacco through a long pipe attached to a bowl of water. They continue to inhale addictive cancer-causing chemicals and nicotine.
And Unlike regular cigarettes, shisha burned using charcoal so that users could also be exposed to toxins from the dangerous carbon monoxide. Carbon monoxide levels in the body from smoking the shisha can be up to 17 times higher than ordinary cigarettes and may cause carbon monoxide poisoning.

By looking at the evidence as a whole also found that smoking shisha is able to at least double the risk of lung cancer and probably also related to some other types of cancer.
The only best way for smokers to reduce their existing cancer risk, as well as improve their overall health, is to quit smoking. There is already abundant evidence of scientific research showing that smoking can cause cancer, even death!
