This treatment is not chemotherapy. It is used to reduce the damage caused to the bones by the cancer. It works by helping the bones to heal where damaged and increasing the strength of the bones. By doing this it reduces pain, fractures and the need for radiotherapy to treat bone metastases.

The treatment schedule below explains how the drug for this treatment is given.

Denosumab (Xgeva®)
This treatment cycle is repeated every 28 days. Your doctor will advise you of the number of treatments you will have.

Changes to your dose or treatment delays

Sometimes a treatment may be started at a lower dose or the dose needs to be changed during treatment. There may also be times when your treatment is delayed. This can happen if your doctor thinks you are likely to have severe side effects, if you get severe side effects, if your blood counts are affected and causing delays in treatment, or if you are finding it hard to cope with the treatment. This is called a dose reduction, dose change or treatment delay. Your doctor will explain if you need any changes or delays to your treatment and the reason why.
