All treatments (procedures or medications) have risks despite the highest standards of care.

While your doctor makes every attempt to minimise risks, any complications may have permanent effects.

The doctor cannot guarantee that the treatment will always be successful or that there is no risk. The treatment and its outcome might not meet your expectations.

It is not usual for a doctor to outline every possible complication.

However, it is important that you have enough information to fully weigh up the benefits, risks and limitations of a treatment.

Any discussion of frequency of risks or benefits ( e.g. 1 patient in a 100, rare etc.) can only be estimates as outcomes of clinical research can vary widely. Such outcomes can depend on many factors.
