Abstract
Cancer patients suffer from a variety of pains. In the workshop of cancer care and palliative medicine, we have more opportunities today to learn the mental support to cancer patients than in the past. We also see the increased level of mental support by the medical staff. On the other hand, when mentally weak patients are diagnosed as cancer, they tend to become the risk of suicidal ideas or behaviors (for example, mental patients having difficulties such as developmental delay, personality and emotional problems, etc). Mental burdens such as accustomed pains, death of familiar people, no place to live, inconvenience to others bring a considerable decline of QOL and are perceived as reinforced psychological problems. The psychiatric staff members are requested to play an important role to give professional support to these people.
