This study explores the life experiences of young youths with cancer in Taiwan and is designed by using Edmund Husserl’s Phenomenology method. Purposive sampling and case selection require participants to be between ages of eleven to eighteen whose cancer is pathologically confirmed, to be self-identified as cancer patients and to be able to communicate in Taiwanese or Chinese. They must acquire their parents or guardians’ consent before participation. Data of each one-on-one interview are analysed by Colaizzi's seven stages method (1976) where sixteen cases studied are divided into four main themes and seventeen sub-themes. First main theme is unconnected solo with subthemes of delayed education, limited activities, absence of peer relationships, and dull life. Second one is suffering rondo and it includes sufferings from symptoms, sufferings from therapies, torment from cancer recurrence, the feeling of being trapped in hospital, and the burden of food therapy. Next theme is string quintet of heart, which includes fear, worry, sadness, anger, and loneliness. Finally we have sunward aria that includes strong family relationships, optimistic thinking and healthy lifestyles. These young youths with cancer are under enormous suffering and stress and in order to improve their quality of life, health care providers should develop not only physical care but also emotional care by understanding their life experiences. This study also suggests that educational institution should establish certain learning system suitable for young patients such as distance learning. It’s also beneficial that nurses conduct health education classes directly in their schools so these young patients' classmates can become more aware and sympathetic of their illness.
