Regarding the diagnosis of cancer, the author of the textbook states: "Psychological research shows that how someone responds to a diagnosis may have a long-term impact on that person's psychological as well as physical health" (page 381). Why, specifically, do you feel that this is the case? This is primarily a psychosomatic issue, where the mind is affecting the body. What is your opinion of the psychosomatic implications involved here, not only with the diagnosis of cancer, but with other health-related issues as well, such as chronic illness, back pain, chronic fatigue syndrome, etc.? Elaborate on all of this.
