The experience of weight gain during and after breast cancer treatment: a qualitative study

After breast cancer diagnosis and treatment, the majority of women will gain weight. The aim of this study was to describe the experiences of weight management among Australian women with breast cancer.

This is a secondary analysis of data from a qualitative study evaluating the feasibility of novel interventions for weight management after breast cancer. Participants were recruited via email invitation from a breast cancer consumer organization and breast cancer centre in Australia. Eligible participants had received treatment for breast cancer, and were fluent in English. Discussions were audio-recorded, transcribed verbatim and analysed using thematic analysis with the constant comparison method.

Thirty-seven women provided data in five focus groups and one semi-structured interview. Four themes were identified: Timing, milestones and turning points; Making sense of the journey; Factors leading to weight gain; and Information and health professional support. Varying trajectories of weight gain were described, the most common being gradual or fluctuating weight gain. Weight gain was attributed to a number of related factors including becoming postmenopausal, and the impact of treatment effects. Achieving a sense of autonomy and agency assisted with weight management. An overall lack of information and support relating to weight management was highlighted.

There is a need for a coordinated and systematic approach to weight management after breast cancer. Further research on the role of supportive care and systems-level support is warranted to mitigate the significant public health burden of excess weight after breast cancer treatment.
