Agreeing to medical treatment is called ‘consent’. A provider of health care must take reasonable steps to make sure that a patient is able to give informed consent to treatment. This means you must be able to understand key aspects of any treatment suggested before asked whether you agree to the treatment. Key aspects include, for example, what the treatment involves and the potential risks of that treatment. You agreeing to the treatment once you have been given the information and state that you understand what you have been told, is called ‘informed consent’ to treatment. Informed consent by a person who has capacity has validity.
