The following paper will reflect on my practicum experience at the Saskatchewan Cancer Agency, Allan Blair Cancer Centre. Utilizing critical self-reflection, review of current literature, and theory, I will highlight my learning goals and use these to focus on the contribution of the oncology social worker while stressing the importance of the multi-disciplinary team, the person centred approach to care, and best practice interventions with cancer patients. I will also describe how systems theory and the strengths perspective help to guide practice. Likewise, as I wanted to evaluate my own effectiveness in this occupation I will use relational theory to explore this in depth. Lastly, I will explain the importance of ethical practice in cancer care and suggest areas of emerging concern.
