<p>Background: This paper addresses a gap in the literature on breast cancer-related arm morbidity care regarding clinician responsibility for the management of women’s treatment-related arm morbidity needs. Using a qualitative research method, the authors spoke to general practitioners (GPs) about their perceptions, knowledge and experiences of breast cancer-related arm morbidity, and what role, if any, they thought they should or could play in this facet of women’s breast cancer-related care.</p>n<p>Methods: The study utilised qualitative, in-depth semi-structured interviews. Interviews lasted approximately 30–45 minutes and were audio-taped. Digital audio files were transcribed verbatim and analysed thematically.</p>n<p>Results: GPs are prepared to engage in the care of patients with breast cancer-related arm morbidity. However, several gaps were noted in GPs’ knowledge and understanding of these conditions, and the majority of GPs did not examine their patients specifically for signs of arm morbidity.</p>n<p>Conclusions: There are a number of gaps in GPs’ knowledge, understanding and experiences with breast cancer treatment-related arm morbidity, and there is a need for education about the complex nature of this condition. GPs are well positioned to improve the care that women living with arm morbidity need to receive.</p>n<p>Declaration of interest: None.</p>
