• where it is

• explain the treatments, benefits and side effects
• work with you to create a treatment plan that is best for you
• help you manage any side effects, including changes to your diet
• help and support you during your recovery

You'll have regular check-ups during and after any treatments. You may also have tests and scans.

If you have any symptoms or side effects that you are worried about, talk to your specialists. You do not need to wait for your next check-up.
