Does lumpectomy treat breast cancer?

During a lumpectomy, the surgeon removes the known cancer with a border of normal-looking tissue. The remaining breast is preserved, although its shape or appearance can change. Tissue from the operation is examined to check the margins and to clarify the cancer's features.

A lumpectomy is usually considered when the cancer can be removed safely while leaving an acceptable amount of breast tissue. Tumour size, position, breast size, imaging findings, more than one area of disease, and previous treatment all affect the decision. Removing the visible tumour does not by itself address cancer cells that may be elsewhere in the body.

Ask the breast team how the scan results and biopsy findings affect the surgical choice. The plan may include lymph-node assessment and treatment after surgery, such as radiotherapy or medicines selected for the tumour's biology. The pathology report after lumpectomy helps determine whether the margin is clear and whether the next step should change.

Before surgery, discuss recovery, wound care, pain relief, activity limits, and whether a further operation could be considered if the margin contains cancer. A second opinion can help when the options feel difficult to compare.

Contact the surgical team promptly for increasing redness, warmth, swelling, drainage, fever, worsening pain, or a wound that opens. Seek urgent help for severe breathlessness, chest pain, fainting, or heavy bleeding. A new breast change, persistent lump, nipple change, or unusual discharge also deserves clinical assessment rather than self-diagnosis.

Which features make lumpectomy suitable for me? Will lymph nodes be checked? What margin is the surgeon aiming for? Could radiotherapy, hormone treatment, chemotherapy, or targeted treatment be recommended? How will the pathology report guide the next decision? What breast changes should I expect during healing?
