Using the saturation criterion, 18 sessions of the referred support group were selected, in which, in total, 93 women participated. The collected data were submitted to a qualitative appreciation by a thematic analysis of content. The obtained results show that breast cancer diagnosis caused, among an expressive number of participants, an important psychological impact, once unchained surprise and tension experiences, stimulated acceptance and force demonstrations, motivated explanation attempts, redefined relationships and intensified religiosity. The comprehension of each one of those processes, in their positive and negative dimensions, supplies useful elements for the improvement of psychological services offered to this population.
