Correlating Risk Factors
Non communicable diseases are not spread by person to person but instead causes by risk factors.
Types of Non Communicable Dieses
When a cell becomes cancerous, it begins to grow and divide uncontrollably. New cells are produced – even if the body does not need them. Causing tumours.
Benign-Grows slowly; usually grow within a membrane, so can easily be removed; does not invade other parts of the body
Malignant-Grows quickly; invades neighbouring tissues and can spread to other parts of the body in the bloodstream; as the tumour grows, cancer cells detach and can form secondary tumours in other parts of the body - this is called metastasis.
The main life style factors for:
the chemical carcinogens in cigarette smoke increasing the risk of lung cancer
alcohol intake is linked with certain cancers
exposure to ultraviolet radiation, part of which is ionising, during sunbathing or outdoor activities, leading to the development of skin cancers
diet, including fat and salt intake, increases the risk of cancer
what you do and the causes
Smoking increases the risk of cardiovascular disease in several ways:
Smoking damages the lining of the arteries, including the coronary arteries. The damage encourages the build-up of fatty material in the arteries. This can lead to a heart attack or a stroke.
Inhalation of carbon monoxide in cigarette smoke reduces the amount of oxygen that can be carried by the blood.
The nicotine in cigarette smoke increases the heart rate, putting strain on the heart.
Chemicals in cigarette smoke increase the likelihood of the blood clotting, resulting in a heart attack or stroke.
Effects on the liver and Brain
Drinking excess alcohol can damage the liver, the organ responsible for processing and breaking down alcohol.
Alcohol affects the brain in several ways, it:
The liver can regenerate its cells, but long-term alcohol abuse causes serious damage
