Immunotherapy
The immune system is made up of many different cells (including T – cells) which act as a defence mechanism for the body. Normally the T – Cells find and destroy any cells which they think are a foreign body, such as, bacteria, viruses and cancer cells.
Cancer develops when abnormal cells are undetected by the T-cells. The reason for this is that cancer cells can block the activity of the T-cell so that they are hidden and can carry on growing and dividing.
Immunotherapy works by unblocking the activity of the T-cell. This then gives the T-cell the ability to recognize that there are abnormal cancer cells in the body and start to fight them.
Immunotherapy is not used to treat all types of cancer, as some cancers respond better to chemotherapy. Your oncologist will advise you of your treatment options.
