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.
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.
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.
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.
For a blood alcohol level of 0.15%, the risk of causing an accident is 25 times higher. Never drink and drive.
Unintentional injuries caused by falls, traffic accidents or unintentional poisoning (such as drug overdose) are a leading cause of death, and the first cause of death for those between 1 and 45 years old.
