Women like those described above usually experience pain through what is known as a metastatic tumour, which simply means it has spread to beyond the breast to other parts of the body such as the bones and liver.
The study in question involved 124 women who were suffering with breast cancer. The group was split into two with half given hypnotherapy as part of group therapy sessions and the other half receiving nothing.
Over the course of the next year the participants continued to receive treatment and their pain levels were monitored throughout.
Though the hypnotherapy seemed to have no effect on the frequency of their pain it did appear to ease any discomfort when it happened.
