Cigarette smoking causes

• A. Lung cancer
• B. Baldness
• C. Colour blindness
• D. None of the above

Answer 1

The correct option is A Lung cancer

Cigarette smoking causes lung cancer by damaging the cells that line the lungs. When we inhale cigarette smoke, which is full of cancer-causing substances (carcinogens), changes in the lung tissue begin almost immediately. At first our body may be able to repair this damage. But with each repeated exposure, normal cells that line our lungs are increasingly damaged. Over time, the damage causes cells to act abnormally and eventually cancer may develop. People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Even smoking a few cigarettes a day or smoking occasionally increases the risk of lung cancer. The more years a person smokes and the more cigarettes smoked each day, the more risk goes up. Cigarette smoking causes many types of cancer, including cancers of the lung, oesophagus, larynx (voice box), mouth, throat, kidney, bladder, pancreas, stomach, and cervix, as well as acute myeloid leukemia.
