What factors may predispose a person to cancer?

11 Nov 2013

It is important for the public to get an idea about situations that can predispose them to cancer as some of them are avoidable or modifiable. Factors that predispose individuals to medical conditions are called risk factors.  The risk factors that are commonly incriminated include smoking, consumption of alcohol, HIV& AIDS infections and excessive exposure to sunlight. Some cancers are known be caused by more than one risk factor (multi-factorial). Situations where a person may be at a higher risk of developing cancer can be classified under four broad groups, as given below. Behavioural risk factors: These are things that you do which may lead to the development of cancer.  These include smoking, drinking alcohol; chewing betel, tobacco or areca nut; eating unhealthy foods, consumptions of certain hormones, exposure to excessive UV light using ‘tanning beds’, being overweight and not taking enough exercise.
