Breast conserving therapy (BCT) is the standard treatment for early breast cancer patients, but the cosmetic outcomes are sometimes poor and influence the quality of life. Oncoplastic surgery is the method modified from breast reduction surgery. Now, oncoplastic surgery was demonstrated by several authors using retrospective analyses. It seems to be safe and widely used now.
　　Oncoplastic surgery defines the appropriate adequate surgery to excise the lesion in the breast combined with partial or total reconstruction (immediate or delayed) with access to a full range of techniques to correct excision defects 1. In general techniques may range from simple mastectomy by separating the breast parenchyma from the pectoralis fascia for better re- closure of small defects to extensive local parenchymal flaps by breast reduction techniques for tissue displacement or lavish procedures such as pedicled or free myocutaneous flaps for tissue replacement
　　However, there are several indications including Breast/Tumor size relation (resection of at least 20% of the breast) Tumor location (central and medial) and Macromastia and Ptosis. Several authors reported about advantages of oncoplastic surgery. However, no prospective randomized or retrospective trial comparing lumpectomy and oncoplastic surgery. Thus, there is only little evidence that oncoplastic surgery may in fact improve oncologic results. However, the possibility of increased resection volume plays a central role in raising the rate of BCT. This may reduce the necessity of performing neoadjuvant therapy in patients with a large breast cancer or an unfavourable breast/tumor size relation and thus, improving quality of life. Oncoplastic surgery may also reduce the re-excision rate.
　　Beside the prolongation of operative time, oncoplastic techniques my increase local morbidities. Skin necrosis and wound dehiscence are the most often reported complications after oncoplastic surgery. Obese patients, smokers and patients with diabetes bear an increased risk to develop local complications.
