Oncoplastic lumpectomy combines plastic surgery techniques with lumpectomy surgery to give you a better cosmetic outcome after the cancer is removed, or to give women with larger tumors more options for breast conservation.

You can think of oncoplastic lumpectomy — also called oncoplastic surgery— as a reconstructive surgery aimed at preventing problems with the breast’s appearance that can be caused by the lumpectomy. It is usually done at the same time as lumpectomy.

There are many different oncoplastic approaches that surgeons can use to reshape the breast after removing the cancer. These choices are tailored to the cancer’s location and size, as well as an individual woman’s breasts, body, and preferences.

Oncoplastic surgery techniques are generally used to either:

  • Rearrange nearby breast tissue to fill in the space left behind after the cancer is removed to prevent “dents” and place the scar where it is less visible.
  • Remove the breast tissue containing the cancer and combine this procedure with a breast reduction, a breast lift, or both. This is usually done together by a plastic surgeon.

If necessary, the surgeon can also alter the other breast to create a symmetric appearance.

If you’re eligible for lumpectomy, you may want to ask your surgeon if an oncoplastic approach makes sense for you.

Traditional Lumpectomy vs. Oncoplastic Surgery: What’s the Difference?

Lumpectomy — also called partial mastectomy or breast-conserving surgery — removes the breast cancer and a rim of healthy tissue called a margin, preserving most of the breast. In some cases, a divot or dent forms and causes a visible indentation of the breast or can distort the appearance of the nipple. Radiation therapy can also change the appearance and shape of the breast and scar.

Oncoplastic lumpectomy combines plastic surgery techniques with lumpectomy to both remove the cancer and reconstruct and reshape the breast. It can be useful for achieving a good cosmetic outcome in many women who choose lumpectomy, such as those who have:

  • Mid- to large-sized breasts and the need to have a large amount of tissue (20-50 percent) removed from the affected breast.
  • Existing issues with their breasts, such as excessive sagging (ptosis), very large size (macromastia), or obvious lack of symmetry (balance), which could be addressed at the same time the cancer is removed.

The procedure may not be possible if there are multiple tumors throughout the breast or if a woman has a small breast size.
