Lumpectomy is a surgical procedure done to remove cancer cells and other affected tissues from the breast. Lumpectomy is also known as breast-conserving surgery, wide local excision or partial mastectomy. In this surgery, only a small portion of the affected breast is removed. Sometimes, doctors may advise lumpectomy as an excisional biopsy procedure. In this surgery, while the doctors remove the affected lump, they also take some part of the surrounding normal or healthy tissue just to ensure that all the affected cells are removed. Lumpectomy is a very useful and effective surgical procedure as it assists in detecting cancer cells at an early stage. It is usually the first choice of treatment in many breast cancer cases. If the cancer cells are further detected after lumpectomy, the procedure of lumpectomy is followed by radiation therapy, in order to prevent the recurrence of the cancer cells. The lumpectomy is usually performed on a solid mass of breast, to detect its malignancy.
