Causes and types of cancer pain

Cancer pain has many different causes and there are different types. You can have pain control and get support to help you manage any pain you might have.

Causes of cancer pain

Most cancer pain is caused by the tumour pressing on bones, nerves or other organs in the body.

Sometimes pain is due to your cancer treatment. For example, some chemotherapy drugs can cause numbness and tingling in your hands and feet. Or they might cause a burning sensation at the spot where you have the drug injection.

Radiotherapy can cause skin redness and irritation.

Remember that some pain might have nothing to do with your cancer. You could have the general aches and pains that everyone gets from time to time.

Acute and chronic pain

Cancer pain can be acute or chronic.

Acute pain

Acute pain is due to damage caused by an injury and tends to only last a short time. For example, having an operation can cause acute pain. The pain goes when the wound heals. In the meantime, painkillers will usually keep it under control.

Chronic pain

Chronic pain can be due to changes to the nerves. Nerve changes may be due to cancer pressing on nerves or due to chemicals produced by a tumour. It can also be caused by nerve changes due to cancer treatment. Chronic pain continues long after the injury or treatment is over and can range from mild to severe. It can be there all the time.

Sometimes pain can come on quickly, for example when you have a dressing changed or you move around and change position. This type of pain is called incidental pain.

Chronic pain is also called persistent pain.

Types of cancer pain

It is extremely important for your doctor to find out the type and cause of your pain. Then they can treat it in the right way. Different types of pain need different treatment. 

How much pain you might have

The amount of pain you have with cancer depends on:

  • the type of cancer you have
  • where it is
  • the stage of your cancer
  • whether the cancer or treatment has damaged any nerves

Other factors can also affect how you feel pain, such as fear, anxiety, depression and a lack of sleep.

It’s very important to let your medical team know straight away if you have pain. Don’t try to put up with it. This can cause nerve changes that could make the pain harder to control in the future.

Controlling chronic pain

Chronic pain is also called persistent pain. It can be difficult to treat, but often painkillers or other pain control methods can successfully control it.

Pain that is not well controlled can develop into chronic pain. So it is important to take the painkillers that the doctor prescribes for you. Trying to put up with the pain can make it harder to control in the future.

People with chronic cancer pain might have times when their medicines do not control the pain all the time. This is called breakthrough pain.

Tell your doctor or nurse if you’re taking regular painkillers but still get pain at times. They can prescribe extra doses of painkillers for you to take when you need them.

Getting support with cancer pain

Pain can greatly affect your quality of life. Chronic pain can make it hard for you to do everyday things such as bathing, shopping, cooking, sleeping and eating.

This can be hard for your close friends and relatives to understand. You might need support to deal with how pain can affect you and your loved ones
