My personal belief is that for many cancers, psychological factors are of considerable importance. At the very least, psychotherapy can increase the quality of your life, no matter how much time you have left, because it will help you cope with this most stressful and fearful time. Psychotherapy may have the added benefit of clearing any emotional baggage that might be in the way of your healing. Unfortunately, at the mention of psychological influences, many people immediately assume that there are no aspects of their past that could negatively impact their healing. Since this material is unconscious and denied, it is difficult for a person to accurately judge this within themselves.
Many people are also frightened by psychotherapy.
