Most cancer pain is caused by the tumour pressing on bones, nerves or other organs in your body. Sometimes pain is related to your cancer treatment like chemotherapy drugs which can cause numbness and be tingling in your limbs or a burning sensation at the place where they are injected. Radiotherapy can cause skin irritation.

Also, You may have the general aches and pains that everyone gets from time to time.

Cancer pain can be acute or chronic. 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 is pain caused by changes in nerves. Nerve changes may occur 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. The pain continues long after the injury or treatment is over and can range from mild to severe. It can be there all the time and is also called persistent pain. Chronic pain can be difficult to treat, but painkillers or other pain control methods can successfully control it in about 95 out of every 100 people.

The amount of pain you have with cancer depends on

• The type of cancer you have
• Where is it?
• The stage of your cancer
• Whether cancer or treatment has damaged any nerves
• Other factors such as fear, anxiety, depression and a lack of sleep can also affect how you feel pain.

If you have pain it is very important to let your pain physician know straight away. If you try to put up with the pain, this can lead to nerve changes that may make the pain harder to control in the future.
