How effective is breast surgery for treating breast cancer?

Very effective: Surgery more effective today then in previous years because of early dx by mammo. Here non palpable tumors or DCIS is detected and wide resection with adequate margins free of disease can give close to 90% to 95% cure or better when RT employed if needed

Very Effective: Surgery is the primary curative treatment for most breast cancers. It can often remove all cancer cells from the body in early stages. Radiation therapy can be given after a lumpectomy to give similar local control rates to a mastectomy. Systemic therapy (chemotherapy, biologic and hormonal therapy) can also be given in addition to surgery to address the risk of cells in the bloodstream.
