Lung Disease Data

Smoking and Lung Cancer

Smoking can have harmful impacts on lung function. Cigarette smoke contains harmful chemical such as nicotine, carbon monoxide and carcinogens (cancer-causing chemicals).

Bronchitis

When smoke is breathed in, it damages the cilia cells of the airways.
This means the cilia can't waft away the mucus produced by goblet cells, and the mucus builds up.
This can lead to bronchitis, where the airways are partly blocked with mucus.

Cancers

The carcinogens can cause tumours to form in the airways.
- Smoking can cause mouth, throat and lung cancers.

Emphysema

Smoke damages the walls of the alveoli, reducing their surface area.
This can cause emphysema, where gas exchange can't happen efficiently, causing shortness of breath.

Heart disease and strokes

Nicotine is very addictive and puts strain on the heart.
Carbon monoxide reduces the ability of red blood cells to carry oxygen, which can also put strain on the heart.
Both of these substances can cause heart disease and strokes.
