Factors influencing cosmetic outcome in breast conservation

With more than 1 million new cases each year, female breast cancer is the second most common cancer in the world and the most common cancer among women. Breast cancer involves a multimodality treatment and a co-ordinated approach from various specialties. Breast-conserving therapy (BCT) is increasingly being integrated into the management of breast cancer. The obvious advantages of BCT are equivalent local and distant control rates as compared with mastectomy and the preservation of the breast. However, the key to a successful BCT is achieving a cosmetic outcome that is acceptable to the patient and the physician. Cosmesis in breast cancer is the end result of a range of factors that fall under the broad heads of surgery, radiotherapy, chemotherapy and hormonal treatment. All of these modalities can play a role in compromising breast cosmesis. This overview discusses the factors that are critical in affecting the final cosmetic outcome in patients with BCT.
