Background: Breast cancer is the most common type of cancer among women. A range of treatments are offered, all of which have side effects. Previous research has shown that women suffer from various side effects associated with breast cancer treatment. Knowledge of the women's experiences is needed, to provide support and good care.

Aim: The aim of this study was to describe women’s experiences of side effects caused by breast cancer treatment.

Method: This literature-based study was based on qualitative research. Friberg's five-step model was used in the analysis of the study. Eleven articles were analysed.

Results: Four themes and eleven subthemes were identified. Themes that emerged were A different body, Different everyday life, Adherence to treatment and The need for knowledge and to be seen. A different body describes bodily-, sexual-, and cognitive changes. Different everyday lifedescribes how the women´s daily lives are limited by the different side effects. Adherence to treatment highlights emotions and how the emotions affected the women´s adherence to breast cancer treatment and The need for knowledge and to be seen describes experiences of lack of information and support.

Conclusion: Women experience several challenges during breast cancer treatment. By having a holistic perspective and conducting person centred care, side effects can become more manageable, and women's suffering can be alleviated.
