it is not uncommon for patients suffering from cancer to feel pain. Pain can be caused from the cancer itself, or from the treatments used to battle cancer, like chemotherapy treatment, radiation therapy and surgery.
Cancer can cause pain as it grows by destroying or pressing on nearby structures inside the body, such as nerves, organs and bones. Cancer that spreads from its original site (primary tumour) can travel to other parts of the body (metastasis) causing injury to these other sites by growth and damaging nearby structures here as well.
Not only can the cancer itself cause pain, but the treatments used to treat cancer can also cause pain. Surgery is done by a cancer specialist to remove all or as much of the cancer as possible. The recovery from surgery can be painful and takes time to heal and recover.
Radiation and chemotherapy can also cause pain after treatment due to injury to nearby structures. Some of the common side effects from these cancer treatments can include:
- Mucositis – painful sores around the mouth.
- Peripheral neuropathy – numbness and painful sensations in the feet, legs, fingers, hands and arms
- Nausea and vomiting
- Abdominal cramps
- Bone and joint pain
