Dent or Deformity After Lumpectomy: Reconstruction Options

Why do lumpectomy and radiation change the breast?

Lumpectomy, typically followed by radiation, is the most common surgical treatment for breast cancer in the United States. For many women the cosmetic impact is minor. For others, particularly after radiation, the breast is left with significant changes: asymmetry, contour irregularities, skin tethering, scarring, and sometimes pain or restricted movement.

When breast tissue is removed, the surrounding tissue fills the void imperfectly. [Radiation compounds this through fibrosis](link: after radiation page): permanent scarring and reduced blood flow in the treated area. The combined effect can produce dimpling, hollowing, or visible deformity at the lumpectomy site. These changes are not simply aesthetic. They can affect how clothing fits, how the breast feels, your sense of your body after treatment, and in some cases physical comfort and range of motion.

How is a lumpectomy deformity reconstructed?

We approach this as a problem of tissue quality, not just contour. Radiated tissue has reduced blood flow, and reliable reconstruction requires bringing healthy, well-vascularized tissue to the area.

• Local perforator flap surgery. For more significant deformities, we use microsurgical techniques to move adjacent tissue, with its own robust blood supply, into the area of need. The three flaps we use most frequently are the ICAP (intercostal artery perforator), TDAP (thoracodorsal artery perforator), and IMAP (internal mammary artery perforator) flaps. Each has its own donor site, scar pattern, and indications.
• Fat grafting. Fat grafting can improve contour irregularities and hollowing, but radiated tissue limits how well transferred fat survives. It is often most effective as an adjunct to flap reconstruction, or for smaller, contained deformities.
• Combined approaches. Many women benefit from a combination of techniques, performed in sequence, to address the full range of changes.

Why is this work specialized?

Local perforator flap reconstruction after lumpectomy and radiation is not performed by many plastic surgeons. It requires microsurgical training, comfort operating in radiated tissue, and deliberate surgical planning. We have performed these procedures extensively and consider them part of the specialized work Altris exists to do.

Is reconstruction after lumpectomy right for you?

Not every lumpectomy-related change requires surgery, and not every woman is a candidate. Candidacy depends on the extent of the deformity, the degree of radiation fibrosis, overall health, and personal goals. If you have been told nothing can be done about your post-lumpectomy result, come in for a second opinion. You may have more options than you have been led to believe.
