The potential effects of smoking, such as lung cancer, can take up to 20 years to manifest themselves. Historically, women began smoking en masse later than men, so an increased death rate caused by smoking amongst women did not appear until later. The male lung cancer death rate decreased in 1975—roughly 20 years after the initial decline in ...
Cigarettes are known to cause many lung diseases including emphysema, chronic bronchitis, and lung cancer. Smoker's macrophages are alveolar macrophages whose characteristics, including appearance, cellularity, phenotypes, immune response, and other functions, have been affected upon the exposure to cigarettes.

One of the most well known diseases caused by smoking is lung cancer. A few carcinogens commonly found in tar include benzene, acrylamide and acrylonitrile. Smoking exposes delicate cells inside the lungs directly to these compounds. This causes mutations in the DNA of the cells, which leads to cancer.
Those who smoke can reduce their lung cancer risk by quitting smoking – the risk reduction is greater the longer a person goes without smoking. [84] Self-help programs tend to have little influence on success of smoking cessation, whereas combined counseling and pharmacotherapy improve cessation rates. [ 84 ]
Smoking tobacco causes various types and subtypes of cancers [94] (particularly lung cancer, cancers of the oropharynx, [95] larynx, [95] and mouth, [95] esophageal and pancreatic cancer). [18] Using tobacco, especially together with alcohol , is a major risk factor for head and neck cancer . 72% of head and neck cancer cases are caused by ...
The consumption of tobacco products and its harmful effects affect both smokers and non-smokers, [9] and is a major risk factor for six of the eight leading causes of deaths in the world, including respiratory diseases, cardiovascular diseases, cerebrovascular diseases, periodontal diseases, teeth decay and loss, over 20 different types or subtypes of cancers, strokes, several debilitating ...
The WHO’s International Agency for Research on Cancer classifies alcohol as a “Group 1” carcinogen, meaning there’s sufficient evidence that it can cause cancer in humans. Other ...
Histone modifications are another epigenetic phenomenon known to be affected by smoking. Cigarette smoke has been observed to globally alter histone modifications near the promoter regions of pro-inflammatory genes, mainly through an overall increase in acetylation. [3] [5] Cigarette smoke can alter histone acetylation through a number of pathways.
