THE
power of positive thought can help cancer patients live longer by boosting
their immune systems, according to new research.
The
research, presented at a British Psychological Society conference yesterday,
described how women diagnosed with cancer and trained in 'relaxation'
techniques developed more cells equipped to fight the disease.
Professor
Leslie Walker of Hull University worked with 80 women who had just been
diagnosed with breast cancer. All received normal treatment, including
chemotherapy, radiotherapy, hormone therapy and surgery.
But
half were also trained in relaxation techniques and guided imagery, where
they visualised their bodies' own defences fighting and overcoming cancer
cells.
By
the end of the 37-week trial, the second group a showed strengthened immune
systems. Levels of the white cells that play a vital role in fighting
disease increased and the 'killer cells' which scout out and destroy infected
or cancerous cells also became more active. Certain types of stress suppress
the immune system. Walker said:
'Some
of the muscle-relaxing exercises were specifically developed to help people
"switch off" their natural "fight/flight" response to high levels of stress.
This results in real changes in internal organs, and also affects white
blood cells.'
Throughout
the usually distressing post-diagnosis and treatment period, the 40 women
doing relaxation and visualisation therapy reported real improvements
in their quality of life.
Walker
said: 'Treatments for cancer are often invasive and very upsetting. Developing
straightforward techniques that nurses can teach to patients throughout
the NHS means that the benefits can be widespread.'
