Radiation can be used to control pain by destroying a growing tumour that is invading or interfering with normal tissue, such as when a tumour presses on bones, nerves, or other organs. This may be done with radiation to part of the body or, in rare cases, with radiation to the whole body. Or you may be given a shot with a radioactive medicine.
Radiation therapy is the use of X-rays to destroy cancer cells and shrink tumours. Radiation damages the cells in the area being treated, stopping or slowing the growth of the cancer cells.
Radiation therapy is used to control pain when a growing tumour invades or interferes with normal tissues, such as bones, nerves, or other organs.
Side effects are common with radiation therapy and may depend on what area of the body receives radiation. Side effects can include:
Side effects can be treated with pain medicines and anti-nausea medicines. They usually go away 4 to 6 weeks after treatments are done. Long-term side effects are uncommon.
Radiation therapy can reduce pain by shrinking a tumour. And for cancer that has spread to the bones, walking and moving around may be less painful after this treatment. One or more treatments may be needed to relieve pain.
