Oncoplastic Breast Reduction: Cancer Surgery and Reconstruction Together

By Dr. Killeen, published on April 6, 2026

You deserve to feel good about your body, and it's so much easier if we're part of things early on in plastic surgery than if you include us later.

What Is an Oncoplastic Reduction?

An oncoplastic reduction is a breast reduction performed at the same time as a lumpectomy for breast cancer. It's a powerful option that combines cancer treatment with reconstruction — but how often it's done depends a lot on where you're getting your care.

How Common Is It?

At centers like Dr. Killeen's, where there's a dedicated breast center, oncoplastic reductions are done all the time. In other environments, they're much less common — and that's a missed opportunity for many patients.

Dr. Killeen believes this procedure should be considered far more often than it currently is.

Why It Matters: Asymmetry After Lumpectomy and Radiation

One of the biggest problems after a lumpectomy followed by radiation is asymmetry. A recent study showed that the average shrinkage of the breast after lumpectomy and radiation is about 30% — leaving many women visibly asymmetric.

This isn't just a cosmetic concern. Significant asymmetry can:

  • Look and feel noticeably unbalanced
  • Affect your neck and back from uneven weight distribution
  • Make clothing and bras difficult to fit
  • Impact quality of life in ways patients don't always anticipate

Does It Affect Your Cancer Outcomes?

This is one of the most important questions — and the answer is reassuring:

Oncoplastic reductions do not have worse oncologic outcomes. In fact, there's some data suggesting they may have better oncologic outcomes. This is likely because a reduction takes significantly more tissue than a standard lumpectomy, creating wider margins around the cancer.

The Problem: Patients Often See Plastic Surgery Too Late

Dr. Killeen regularly sees patients who had a lumpectomy followed by radiation without ever being referred to plastic surgery first. By the time they come in, they're dealing with significant asymmetry that was often predictable from the start — and managing it after radiation is much more challenging than addressing it at the time of the original surgery.

What You Should Do

If you've been diagnosed with breast cancer and are planning a lumpectomy, especially if you have:

  • Pre-existing breast asymmetry
  • A larger lumpectomy planned (larger lesion being removed)
  • Larger breasts overall

...talk to your general surgeon and request a plastic surgery consultation before your cancer surgery.

Why Early Involvement Matters

Getting plastic surgery involved early means:

  • More options — you can plan an oncoplastic reduction rather than fix problems later
  • Better outcomes — addressing things before radiation is far easier than after
  • One surgery instead of two — treating cancer and reshaping the breast at the same time

The Bottom Line

You deserve to feel good about your body, even after cancer treatment. Oncoplastic reduction is a safe, effective way to combine cancer treatment with reconstruction — and it's one of the reasons Dr. Killeen is passionate about breast reconstruction and breast cancer care. If you're facing a lumpectomy, ask for a plastic surgeon to be part of your team.
