Dealing with the breast cancer diagnosis affects the biopsychosocial structure of the diseased person. Pain as an inevitable multimodal entity is projected in multidimensional way through aspects of human existence and functioning, starting with physical pain which necessarily lies in the nature of surgical treatment of the breast cancer, as well as the invasive neoadjuvant therapies; all to psychological and emotional dimensions of pain which are determined by the subjective experience of one's own illness. Distressful factors are undeniable, especially in the early stages of the postoperative procedure. Except for the use of analgesic therapy in the treatment of the postoperative pain, it is proven that nonphfarmacological, complementary therapies-such as Music Therapy-will facilitate the reduction of the pain. The objective of this paper was to question the effect of the receptive Music Therapy on the reduction of the objective influence and subjective experience of the pain in women with localized malignant process in breast and axilla during the postoperative period after the surgical removal procedure of the breast cancer (segmentectomy, mastectomy, dissection of axxilary). This study was carried out with quantitative and qualitative methodology, on the sample of 64 examinees who were hospitalized at the Clinic for tumors in Zagreb due to surgical treatment of the breast cancer and were distributed in the experimental and control groups. Apart from the use of the conventional analgesic therapy in both groups, the additional treatment of the receptive Music Therapy was used with the experimental group. The choice of the music depended on the personal preferences of each participant, and music was listened twice a day in the duration of 30 minutes with the help of the device for reproduction of the music and headsets, during the entire period of the hospitalization. In both groups of participants, the intensity of the pain and the level in which pain interferes everyday functioning was questioned with the assessment tool "Brief Pain Inventory". The objective of the qualitative methodology was to acknowledge individual perspective of the participants about the experience of pain and the contribution of the Music Therapy. The study results have showed statistically significant interactional effect of the treatment of the Music Therapy and the effect of time on variables level in which pain interferes everyday functioning (p<0.05) and level in which pain interferes everyday activities (p<0.05). Accordant to the results, the benefit of the receptive Music Therapy as complementary-supportive therapy with conventional medical and analgesic therapies in the treatment of breast cancer is manifested in efficacy of the treatment of specific variability of postoperative pain, dealing with the subjective experience of the pain, the improvement of the functioning during the period of the hospitalization, the contribution to the facing the breast cancer and its noninvasive character without harmful consequences.
