The research method used is based on the phenomenological line of thought, involving an in-depth exploration of thoughts and views of women with breast cancer who have faced decisions regarding their treatment. Ten women were individually interviewed, and later a group meeting of all these women was held for further discussion. Another group discussion with twelve women attending a 'Reach for Recovery' self-help meeting took place. In addition, seven nurses working as counsellors in breast cancer care were separately interviewed. Twelve themes emerged during the analysis of the data relating to the decision-making experience. These themes suggested a social process of decision-making which was experienced by the women. Three different social realities: the self-world, the relationship with the doctor, and the network of support are discussed in relation to decision-making. The doctor was seen as 'invading' the Self-World, and the Network of Support provided the means by which the women regain the stability of the Self-World. In relation to nurse counselling as a specific form of support, six themes were analysed: the timing of counselling, counselling as a source of information and advice, and emotional support given by the specialist breast-care-nurse-counsellor, the holistic approach to counselling, the training of the counsellor, and finally, the limitations of nurse counselling. A description of the women's and nurses' perceptions of each of these issues is given. The researcher herself and her experiences form an integral part of the research process. Based on the analysis of the data, practical matters related to breast care nurse counselling are addressed.
