The role of narrative and metaphor in the cancer life story: a theoretical analysis.

Being diagnosed with cancer can be one of those critical incidents that negatively affect the self. Identity is threatened when physical, psychological, and social consequences of chronic illness begin to erode one's sense of self and challenge an individual's ability to continue to present the self he or she prefers to present to others. Based on the notion of illness trajectory and adopting a Ricoeurian narrative perspective, this theoretical paper shall explore the impact of cancer disease on identity and establish the crucial importance of metaphor in the narratives of life with cancer. Findings indicate that in cancer narratives the illness experience supplies the narrative structure with temporal and spatial meeting points that make the narrative comprehensible and meaningful. Cancer forces identity changes not only from having to endure the long-term physical and psychosocial effects of the disease, but also from inevitable existential questions about life's meaning. Improved medical knowledge today means improved ethnomedical practices. Metaphor can bridge the gap between the cancer experience and the world of technology and treatment, helping patients to symbolically control their illness.
