Life Expectancy Factors – Smoking

July 26, 2017

A person’s life expectancy can be drastically impacted by smoking. It is a leading cause of preventable death all over the world. People who regularly smoke lose an average of 14 years of life expectancy.

More than half of lifelong smokers die early as a result of smoking. This is due to an increased risk of a variety of illnesses that are caused by smoking. Smoking can increase the risk of lung cancer, lung diseases such as bronchitis and emphysema, heart attacks, pulmonary disease, strokes, other cancers, pneumonia, Alzheimer’s and chest infections. It can also worsen the symptoms of asthma, cystic fibrosis & Crohn’s.

Smoking accounts for a fifth of all cancer cases in the UK. It causes cancers as it contains substances that are carcinogenic (cancer-causing). These substances cause cancer by damaging DNA so that genes that prevent cancer are affected.

Your risk of dying from lung cancer increases from 1% for the general population to 15% for smokers.
