How you might feel

Finding out that you can’t be cured is distressing and can be a shock. It’s common to feel uncertain and anxious. It's normal to not be able to think about anything else.

Lots of information and support is available to you, your family and friends. Some people find it helpful to find out more about their cancer and the treatments they might have. Many people find that knowing more about their situation can make it easier to cope.

Talk to your doctor or specialist nurse to understand:

• what treatment is available

Everyone is different and there is no right way to feel.

Making decisions about treatment

Deciding about treatment can be difficult when you have advanced cancer. Treatments such as chemotherapy or short courses of radiotherapy can help to reduce symptoms and might make you feel better. But they also have side effects that can make you feel unwell for a while.

Ask your doctor to explain what treatment you may have, the possible side effects and how it might affect your quality of life. 

Your doctor might offer you a choice of treatments. You can discuss the benefits and risks of each treatment with them and ask how they can control any side effects. This helps you make the right decision for you. You also need to think about the other factors involved in each treatment, such as:

• whether you need extra appointments

• if you need more tests

• the distance you need to travel to and from hospital

You might have to make further choices as your situation changes. It helps to find out as much as possible each time. You can stop a treatment whenever you want to if you find it too much to cope with.

You might also find it helps to talk things over with a close relative, a friend or a counsellor at the hospital.

Your treatment

Treatment depends on:

• the size of the cancer and where it is in the body
