Which cancer patients are the most probable users of CAM
• 1. Former users of CAM (40% earlier use)
• 2. Patients between 30-60 years
• 3. Knowledge of cancer more than 3 mnd
• 4. Symptoms of their disease (mild)
• 5. Only palliative treatment
• 6. In north Norway: women more than men
Why do cancer patients use Non-Conventional Therapy
• Medical: – Cure (seldom)– Improvement of general health (common)– “man is a rational animal”: a number of the users are
sicker than believed by their physicians. (the “survival study”)
• Coping/Psychological– «Do something/together with the family»– «support in an otherwise hopeless situation»– «advocated by others/earlier experiences»
Sorts of Alternative medicine used by the patients
Depends on:– Geography
• Northern and western parts: «Spiritual forms»• Central parts/Larger cities «Non-spiritual forms»
– Age• Young: Healing by prayers (Miracles)• Middle aged: Prayers/ Traditional forms
(Homeopathy/Injections etc)• Old age: Very little use of NCT
