Surgery is one of the main treatments for breast cancer. The operation you have depends on the size and position of the cancer and your own preference. Your surgeon and breast care nurse will talk to you about your options. You may be asked to decide which operation you have.
Your surgeon will usually recommend surgery that keeps as much of the breast tissue and the shape of the breast as possible (breast-conserving surgery). But in some situations, they may recommend having all of the breast removed (mastectomy). Some women have hormonal therapy or chemotherapy before their operation to try to shrink the cancer to avoid having a mastectomy.
Your surgery will usually include removing some or all the nodes in your armpit.
