What you can prevent if you Do not smoke

Cancer

Risk: very high
Incidence rate: 455 Case fatality: 40.0% (?)
Cancer

Smoking accounts for 30% of all cancer deaths and 87% of lung cancer deaths.

Cancer is a group of diseases involving abnormal cell growth. It is a leading cause of death worldwide, but many cancers can be prevented. The majority of cancers, some 90-95% of cases, are due to environmental factors, such as lifestyle and behaviour, and only 5-10% are genetic.

To prevent: exercise, do not smoke, maintain a healthy weight, limit alcohol intake, limit sunlight exposure

Coronary artery disease

Risk: very high
Incidence rate: 870 Case fatality: 15.0% (?)
Coronary artery disease

Smoking is linked to about 36% of CAD cases. It damages the arteries, raises the blood pressure and reduces the amount of oxygen in the blood, forcing the heart to pump harder.

CAD is the most common cardiovascular disease and a top cause of death. The arteries become narrow as the artery-wall thickens, causing a limitation of blood flow to the heart. Up to 90% of cases may be prevented if the risk factors are avoided.

To prevent: exercise, do not smoke, maintain a healthy weight, limit alcohol intake, eat a balanced diet, check blood pressure, check cholesterol level

COPD

Risk: very high
Incidence rate: 200 Case fatality: 50.0% (?)
COPD

Smoking is the most common cause of COPD. Even at late stages of the disease, Smoking cessation reduces the rate of worsening lung function and delays the onset of disability.

Chronic obstructive pulmonary disease (COPD) is a lung disease involving poor airflow. It affects nearly 5% of the global population. Symptoms include shortness of breath and productive coughing. COPD worsens over time and it has no cure, but its progression can be delayed.

Stroke

Risk: very high
Incidence rate: 300 Case fatality: 30.0% (?)
Stroke

Smoking increases the risk of high blood pressure, which is the biggest risk factor for stroke.

A stroke is a "brain attack". It happens when there is a disruption in the blood flow to the brain and results in cell death. Stroke often leads to permanent disability and is a top cause of death.

Diabetes

Risk: very high
Incidence rate: 590 Case fatality: 2.5% (?)
Diabetes

Smoking raises blood sugar levels and weakens the body's ability to respond to insulin.

Diabetes is a group of diseases in which the level of sugar in the blood is too high. Insulin is a hormone that regulates blood sugar, but in diabetes either the pancreas is not producing enough insulin or the cells are not responding to it. Diabetes can cause many complications and premature death.

Hypertension

Risk: high
Incidence rate: 6,000 Case fatality: 0.1% (?)
Hypertension

The nicotine in cigarette smoke raises the blood pressure and heart rate.

Hypertension, or high blood pressure, is a condition in which the blood pressure in the arteries is persistently elevated. It can have no symptoms, but it's a major risk factor for dangerous diseases. Hypertension affects 25% of the population and is believed to be a factor in 18% of deaths.

Pneumonia

Risk: high
Incidence rate: 1,000 Case fatality: 5.0% (?)
Pneumonia

Tobacco damages the lung's ability to fight infection.

Lower respiratory tract infections (LRTI), the most common types being pneumonia and bronchitis, are inflammatory conditions of the lung. Children and the elderly are at higher risk, but pneumonia is a major cause of death among all age groups, accounting for 7% of the world's yearly total.
