Study the graph below showing the lung cancer deaths and smoking rates in UK and answer the following question: Describe how the number of cigarettes smoked per year by males changed between 1911 and 2001 .

Doctors believe smoking tobacco causes lung cancer by damaging the cells that are present in the mucus lining of the trachea of the lungs. Cigarettes contain tobacco. The complex mixture of chemicals in tobacco smoke includes carbon monoxide, hydrogen cyanide, benzene, formaldehyde, nicotine, phenol, polycyclic aromatic hydrocarbons, and tobacco-specific nitrosamines. When one inhales cigarette smoke, carcinogens enter, and changes in the lung tissue begin almost immediately. From the figure given in the question, it can be suggested that during 1911 , 1500 males used cigarettes which sharply raised to 4500 cigarettes in year 1941 (blue line). However, when the number of deaths (green line) correlated with the increased number of smokers in males, the number of cigarettes been smoked declines to 1500 in 2001 .

Study the graph below showing the lung cancer deaths and smoking rates in UK and answer the following question: Describe how the number of deaths from lung cancer per year in males changed between 1911 and 2001 .

Smoking can cause lung disease by damaging the airways and the alveoli found in our lungs. Lung diseases caused by smoking include COPD, emphysema, and chronic bronchitis. Cigarette smoke contains a number of toxic chemicals that include polycyclic aromatic hydrocarbons (benzopyrene), tobacco-specific nitrosamines, aldehydes, carbon monoxide, hydrogen cyanide, nitrogen oxides, benzene, toluene, phenols. These components are mostly carcinogens. In the given correlation graph, during 1911 , males smoked cigarettes and the number of cigarettes been smoked elevated to 4500 up to 1941 (depicted as blue line). Simultaneously, the number of deaths due to lung cancer increased up to 25 per thousand in the years 1971 - 1981 . After declination of number of smoked cigarettes up to the year 2001 , the number of deaths also declined sharply and become about 15 deaths per year per thousand.

Study the graph below showing the lung cancer deaths and smoking rates in UK and answer the following question: Discuss the extent to which the graph for males provides evidence that smoking cigarettes causes lung cancer.

Doctors believe smoking tobacco causes lung cancer by damaging the cells that are present in the mucus lining of the trachea of the lungs. Cigarettes contain tobacco. The complex mixture of chemicals in tobacco smoke includes carbon monoxide, hydrogen cyanide, benzene, formaldehyde, nicotine, phenol, polycyclic aromatic hydrocarbons, and tobacco-specific nitrosamines. When one inhales cigarette smoke, carcinogens enter, and changes in the lung tissue begin almost immediately. The graph here shows a correlation between the smoking rate and the incidence of lung cancer in the UK. Males used about 1500 cigarettes per year in the year 1911 , which had doubled up to 4500 in the year 1941 (as depicted by blue line). Simultaneously, the green line shows the incidence of deaths per thousand person in the year 1911 was negligible but increased to 25 deaths per thousand living person. When the smoking rates were reduced in the year 1981 - 2001 , the number of deaths due to lung cancer declined to 15 deaths per thousand. This graph indicates a clear positive correlation between the occurrence of lung cancer associated with smoking rates.

Study the graph below showing the lung cancer deaths and smoking rates in UK and answer the following question: Considering the graph dedicated to female population, explain whether it is evident that smoking cigarettes cause lung cancer.

Smoking can cause lung disease by damaging the airways and the alveoli found in our lungs. Lung diseases caused by smoking include COPD, emphysema, and chronic bronchitis. Cigarette smoke contains a number of toxic chemicals that include polycyclic aromatic hydrocarbons (benzopyrene), tobacco-specific nitrosamines, aldehydes, carbon monoxide, hydrogen cyanide, nitrogen oxides, benzene, toluene, phenols. These components are mostly carcinogens. In the study from the female population, the graph shows that the number of cigarettes been smoked by females increased from the year 1931 , which became about 2500 cigarettes in 1971 (as depicted by blue line). The simultaneous green line, shows the incidence of deaths due to lung cancer increased from zero cases to about 15 cases of death per thousand in the year 1991 . This clearly indicates, the occurrence of lung cancer is not gender-specific. The correlation between lung cancer and smoking cigarettes is prevalent equally in both sexes.
