Sharla, you say the surgeons want to do a lumpectomy after the chemo. So I'm not quite sure why you're mentioning a mastectomy. Having a mastectomy would, of course, lessen your chance of a recurrence in the breast. But since the cancer has spread out of the breast, there's no way, unfortunately, to guarantee it won't come back. Chemo will definitely help - but as I said, no guarantee you're cancer free. If you're hormone receptive, then you'll also take long-term drugs, and that'll help, too. Treatment is getting better and better all the time. So - go through treatment, stay positive, take the drugs as directed, and live your life. Worry doesn't accomplish anything. Best of luck to you - and stay connected here, OK? - PJH
