Mapping review

Effectiveness of mastectomy for women with breast cancer: evidence base for a shared decision making tool

My treatment options “Mine behandlingsvalg” commissioned the Norwegian Institute of Public Health to identify and summarize key findings from systematic reviews about the effects of mastectomy for women with small breast cancer tumour (less than four centimetres) and no metastases and without previous cancer or treatment.

Key message

Breast cancer refers to a malignant tumor in the breast. There are several types of breast cancer, most of which originate from the breast glands. The preferred treatment strategy will depend on several factors, e.g. the size of the tumor, the properties of the cancer cells and metastatic status. Treatment decisions are individualised.

My treatment options “Mine behandlingsvalg” commissioned the Norwegian Institute of Public Health to identify and summarize key findings from systematic reviews about the effects of mastectomy for women with small breast cancer tumour (less than four centimetres) and no metastases and without previous cancer or treatment.

We identified one relevant systematic reviews comparing the effectiveness of mastectomy with immediate reconstruction versus mastectomy with the possibility of delayed reconstruction.

We prepared summary of findings tables and plain language sentences to summarize the main results. It is uncertain whether mastectomy affects the complications, aesthetic results and quality of life because we have very little confidence in the evidence.
