Hormones and mood changes
Hormones are natural substances made by the glands of our hormone (endocrine) system. They are carried around our body in our bloodstream.

Talk to your doctor or nurse if you feel sad or anxious and are finding it difficult to cope.

- do relaxation or deep breathing exercises
- take regular exercise that you enjoy, such as walking, swimming or yoga
- avoid alcohol
- get enough sleep – this can be difficult if you are feeling anxious or sad, but lack of sleep can make it harder to cope
- get help to control other symptoms – if you don’t feel well it can make coping with mood changes more difficult
It can help to talk to people about how you feel. Sometimes the idea of talking about your treatment and feelings can be difficult. But speaking to your family and friends can often help you cope.
