Breast cancer is the most common cancer in women. Every year, around 2 million people worldwide are diagnosed with breast cancer and about 600,000 people die from the disease.

Breast-conserving surgery in breast cancer includes many levels: excision of the tumor, partial mastectomy, and quadrant resection of the breast. The surgeon will cut the tumor and surrounding tissue with a safe margin based on the guidance of the ultrasound and mammograms as well as their perception.

The surgical methods for breast cancer can leave serious complications such as: Long scar shrinkage, loss of one breast, restriction of shoulder movement on the operating side... To reduce complications, two doctors Fisher and Veronesi proposed breast-conserving therapy with partial mastectomy with radiation therapy. The success rate and aesthetic results are very positive.
