What the cigarettes they hurt, it is now known. Despite this, many people continue to have the habit. There is a distinction between heavy, weak and occasional smokers. But none of these categories can be considered safe from any tumors. There Veronesi Foundation explains how cigarette smoking is strongly correlated with the onset of 17 types of cancers. In the first place there is lung cancer, which in 8 out of 10 cases depends on the consumption of cigarettes.
To follow, to varying degrees, also the formations carcinogenic of the oral cavity, such as throat, tongue, esophagus; pancreas, colon, bladder, prostate, kidney, breast, ovaries, and some leukemias. So smoking does not create damage exclusively to the organs directly involved in breathing, but extends to wide range throughout the body. The mode of action of cigarettes is explained by the Veronesi Foundation: “Il mix of carcinogenic compounds that is released from cigarettes is in fact able to modify the DNA: both of the cells with which it comes into contact and of those at a distance. This is how the cancer formation process begins “.
Cigarettes, the study on genetic mutation
Obviously there is a correlation between the number of cigarettes consumed per day and the risk of cancer. But it is reiterated that even a weak smoker can get cancer from smoking. The only way to ensure a healthy lifestyle is to abstain from smoking. A study published in “Science” reports that the consumption of 20 cigarettes per day would cause the genesis of over 150 annual mutations. The researchers took a smoker and a control sample of nonsmokers. Specific damage was found to the DNA of smokers, not present in non-smokers.

These mutations have been linked to tumor onset in patients. Carcinogenic substances contained in cigarettes are the basis of the mutation. Concludes the article: “It is now clear, however, that the answer depends on the size of the dose: more cigarettes you smoke, the greater your risk of getting sick cancer. There is no threshold from safety under which the smoke does not cause damage “.
