[en] Introduction: Breast cancer is the most common kind of cancer affecting women worldwide. Both the diagnosis of this disease and its treatment, have a great impact on the lives of these women. There are several treatments available for breast cancer. From these options, mastectomy is considered as one with numerous side effects. Given the symbolic importance of breasts in our society, their removal may be considered a mutilation with direct impact on the patient's sexuality. Objectives: To define the effects on the sexuality of women with breast cancer who undergo mastectomy, explore the factors which influence the most and determine which interventions can be carried out to minimize the impact of this procedure. Development: This review was carried out based on the following databases: BUCea, Dialnet, IBECs, LILASCs, PubMed and SciELO. A total of 15 papers were found complying with the inclusion criteria. Discussion: Women who have undergone a mastectomy showed changes in sexuality manifested by: a decrease in sexual desire, arousal, satisfaction and frequency of intercourse, mainly due to distortion of body image and the derived negative impact on self-esteem caused by this treatment. Conclusions: Mastectomy seriously affects women's sexuality. This is often not considered relevant enough and therefore is not taken into account given that the main medical care focus is placed on disease treatment. There are numerous factors involved which can be modified, so it is important to take into account the characteristics of each patient and their personal situation in order to carry out the most suitable nursing care in accordance with their own individual needs.
