Smoking most commonly leads to diseases affecting the heart and lungs and will commonly affect areas such as hands or feet. First signs of smoking-related health issues often show up as numbness in the extremities, with smoking being a major risk factor for heart attacks, chronic obstructive pulmonary disease (COPD), emphysema, and cancer, particularly lung cancer, cancers of the larynx and ...
People who have smoked cigarettes account for 85–90% of lung cancer cases, and 15% of smokers develop lung cancer. [97] Non-smokers' risk of developing lung cancer is also influenced by tobacco smoking; secondhand smoke (that is, being around tobacco smoke) increases risk of developing lung cancer around 30%, with risk correlated to duration ...
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.

The health effects of tobacco had been debated by users, medical experts, and governments alike since its introduction to European culture. [1] Hard evidence for the ill effects of smoking became apparent with the results of several long-term studies conducted in the early to middle twentieth century, such as the epidemiology studies of Richard Doll and pathology studies of Oscar Auerbach.

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 ...
This study was a retrospective, case-control study that compared smoking habits of 684 individuals with bronchogenic carcinoma to those without the condition. [12] The survey included questions about smoking: starting age, 20 year tobacco consumption, brands used; as well as inquires about exposure to hazardous agents in the workplace, alcohol use, and causes of death for family members.
Survival from age 35 of non-smokers, cigarette smokers and ex-smokers who stopped smoking between 25 and 34 years old. [211] The ex-smokers line follows closely the non-smokers line. Many of tobacco's detrimental health effects can be reduced or largely removed through smoking cessation. The health benefits over time of stopping smoking include ...
