Your doctor will explain details of the surgery, general risks and side effects of surgery. Ask your doctor if you have questions. They may recommend:
stopping blood thinners (e.g. aspirin) before surgery to reduce the risk of bleeding
special stockings to reduce the risk of blood clots
early mobilisation (i.e not staying in bed) to reduce the risk of blood clots and chest infection
antibiotics to lower the risk of wound infection.
Before starting treatment, it is important that you consider stopping smoking to reduce the risk of infection and help you fully recovery after your treatment.
