A lady has cancer of the uterus. She could be cured by a potentially life-saving operation. However, because of other co-morbidities and other factors there is a considerable risk that she could die during the operation or in the post-operative recovery period. She herself lacks the capacity to make an informed decision, but she denies that she has cancer at all and opposes and is resistant to the operation. The medical team at the hospital consider that she would benefit from the operation and would like to perform it. The lady's three adult sons all strongly desire that she should have the operation and feel that the potential benefit outweighs the risk. The Official Solicitor, who acts as her litigation friend, considers, in a phrase, that it is too risky. The question for the court is whether, balancing all the relevant factors, it is in her overall best interests to have the operation or not.
