Causes of Cancer
Most cancer pain is caused by the tumor pressing on bones, nerves or other organs in your body. Pain can also be related to your cancer treatment. For example, some chemotherapy drugs can cause numbness and tingling in your hands and feet or a burning sensation at the place where they are injected. Radiotherapy can cause skin redness and irritation.
Factors That Influence
- 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 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 doctor know right 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.
Types of Cancer Pain
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 away when the wound heals. In the meantime, medication can typically keep it under control.
Chronic pain is pain caused by changes to nerves. Nerve changes may occur due to cancer pressing on nerves or due to chemicals produced by a tumor. 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 medication or other pain control methods can successfully control it in about 95 out of every 100 people.
