Introduction: Breast cancer is the most frequent malignant neoplasm in women. The evaluation of the quality of life has become a treatment parameter as important as survival.
Objective: The aim of the study was evaluation of the quality of life among women treated for breast cancer who underwent surgical procedures using two alternative methods: mastectomy or breast conserving therapy (BCT).
Materials and method: 85 patients treated with BCT and 94 patients who underwent mastectomy were evaluated. Standard questionnaires for the evaluation of the quality of life of cancer patients were used - QLQ-C30 (Quality of life questionnaire - core 30) with QLQ-BR23 (Breast Cancer Module). The Hospital Anxiety and Depression Scale was also applied.
Results: Social and demographic factors (age, education, marital status) influenced the evaluation of the life quality among both groups. Obtained data was also dependent on the type of surgical procedure and chemical treatment. The level of anxiety and depression also influenced the general quality of life and was higher in women who underwent mastectomy.
Conclusions: Quality of life plays an important role in the treatment process. Women after BCT declared a higher quality of life compared to patients after mastectomy. The process of making the decision concerning the planned surgical procedure should take into consideration the influence of the intervention on the quality of patients' future life.
