Double mastectomy without reconstruction: what to know

During a flat closure, the surgeon removes excess skin and shapes the chest wall as part of closing the incisions. The result can be intentionally flat, but scars, folds or asymmetry may remain while healing develops. Sensation may be reduced or altered. Choosing no reconstruction now does not necessarily prevent discussing reconstruction later, and external breast forms or clothing inserts are optional rather than required.

The operation may include lymph-node assessment when the diagnosis calls for it. Breast cancer or Paget disease findings, previous treatment and pathology guide any further medicines or radiotherapy. A flat closure is a treatment and body-image choice, not a sign that follow-up is finished.

Before surgery, discuss the intended chest contour, drains, pain relief, showering, sleep position and when arm movement can begin. Prepare loose clothing and arrange help with meals, washing and transport. Follow dressing instructions, keep appointments and protect the incisions from friction. Gradual shoulder exercises can help restore movement when approved by the team.

If you later want an external prosthesis, a specialist fitter can help after the wounds settle. Ask about scar care once the skin is closed. Swelling of the arm or chest after lymph-node treatment deserves assessment; lymphoedema therapy may provide targeted support.

Report fever, worsening redness or warmth, wound separation, increasing fluid, foul-smelling drainage, or pain that is not improving. Contact the team promptly if one side becomes suddenly more swollen or tense. Seek emergency care for severe breathlessness, chest pain, fainting or sudden collapse.

Ask how flat the closure is expected to be, whether lymph nodes will be assessed, how drains are managed, and which movements are safe. Discuss future reconstruction, external forms, scar treatment, pathology review and the schedule for oncology follow-up.
