Common Abbreviations for Breast Cancer and Reconstruction

A breast cancer diagnosis can feel like being dropped into a foreign country where everyone speaks a language you haven't learned yet. Within days, your conversations with doctors are filled with terms like DCIS, BRCA, DIEP, and NSM, and it can be hard to feel like an active participant in your own care when you're not sure what anyone is actually saying.

This guide aims to change that. Below, you'll find a plain-language breakdown of the most common abbreviations you'll encounter during diagnosis, surgical planning, and reconstruction so you can walk into every appointment feeling informed, prepared, and confident.

Breast Cancer Abbreviations Common After Diagnosis

These are the terms you're most likely to hear early in your diagnosis:

• BRCA (BRCA1 / BRCA2) — The breast cancer gene. Mutations in these genes significantly increase the risk of breast and ovarian cancer. Genetic testing can determine whether you carry a BRCA mutation.
• DCIS (Ductal Carcinoma In Situ) — Early-stage breast cancer. Abnormal cells are contained within the milk ducts and haven't spread to the surrounding tissue.
• IDC (Invasive Ductal Carcinoma) — The most common type of breast cancer. Cancer cells have broken through the duct walls and may spread to nearby tissue.
• ILC (Invasive Lobular Carcinoma) — Cancer that begins in the milk-producing lobules. It can spread to the surrounding tissue.
• HER2 — A protein that promotes cell growth. HER2-positive cancers tend to grow faster, but also respond well to targeted therapies.
• TNBC (Triple-Negative Breast Cancer) — Tests negative for estrogen receptors, progesterone receptors, and HER2. It requires different treatment approaches than other breast cancers.
• ER/PR (Estrogen Receptor / Progesterone Receptor) — Describes whether a cancer's growth is fueled by estrogen, progesterone, or both. This information shapes your treatment plan.

Breast Reconstruction Abbreviations

Once treatment planning begins, you'll encounter surgical terms like these:

• MX (Mastectomy) — Surgical removal of the breast.
• DMX / BMX (Double or Bilateral Mastectomy) — Removal of both breasts. DMX and BMX are often used interchangeably in many practices.
• UMX (Unilateral Mastectomy) — Removal of one breast.
• NSM (Nipple-Sparing Mastectomy) — A mastectomy technique that preserves the nipple and areola. This approach can offer better cosmetic outcomes for reconstruction.
• SSM (Skin-Sparing Mastectomy) — Removes breast tissue while preserving most of the breast skin. Helps create a more natural result during reconstruction.
• OTM (Contralateral Total Mastectomy) — Removal of the opposite breast. Often chosen for symmetry or risk reduction.
• SNB / SLNB (Sentinel Lymph Node Biopsy) — Removes and examines the first lymph node(s) that cancer would likely spread to. Helps determine whether cancer has moved beyond the breast.
• ALND (Axillary Lymph Node Dissection) — Removal of multiple lymph nodes from the underarm area. Typically performed when cancer has been found in the lymph nodes.

Breast Reconstruction Abbreviations

This is where PRMA's expertise comes in. These terms refer to the reconstruction techniques your surgical team may discuss with you:

• DIEP (Deep Inferior Epigastric Perforator) Flap — A microsurgical procedure using skin and fat from the lower abdomen, without sacrificing muscle, to reconstruct the breast. One of the most popular and natural-feeling options available.
• TRAM (Transverse Rectus Abdominis Myocutaneous) Flap — An older technique using abdominal tissue, including muscle, for reconstruction. The DIEP flap is now generally preferred as it preserves abdominal strength.
• PAP (Profunda Artery Perforator) Flap — Uses tissue from the upper inner thigh to reconstruct the breast. This is a strong option for patients who are not candidates for abdominal flap procedures.
• LAP (Lumbar Artery Perforator) Flap — Uses tissue from the lower back for reconstruction.
• TUG (Transverse Upper Gracilis) Flap — Uses tissue from the inner thigh. Often a good fit for smaller breast reconstructions.
• LD (Latissimus Dorsi) Flap — Uses muscle and skin from the upper back. Sometimes used in combination with an implant.
• TE (Tissue Expander) — A temporary implant placed under the skin after mastectomy. Gradually stretches the tissue in preparation for a permanent implant.
• LVA (Lymphovenous Anastomosis) — A microsurgical procedure that reconnects lymphatic vessels to veins. Used to treat or prevent lymphedema.
• VLNT (Vascularized Lymph Node Transfer) — Transplants healthy lymph nodes from one part of the body to the affected area. Used to restore lymphatic function.

Other Common Abbreviations in Breast Cancer Care

You may also come across these terms throughout treatment and recovery:

• NED — No Evidence of Disease. Cancer is no longer detectable after treatment.
• PCR — Pathologic Complete Response. No cancer cells were found in the tissue after neoadjuvant (pre-surgery) treatment — an encouraging sign.
• BMI (Body Mass Index) — May come up when discussing reconstruction candidacy.
• CTA (CT Angiography) — Imaging used before DIEP flap surgery to map blood vessels and plan the procedure.
• WHCRA (Women's Health and Cancer Rights Act) — A federal law requiring health insurers to cover breast reconstruction after mastectomy.
• BCS (Breast-Conserving Surgery) — Also called a lumpectomy, it removes the tumor while preserving most of the breast.
• DX / TX / RX / SX (Diagnosis, Treatment, Prescription, and Surgery) — Shorthand you may see in medical notes.
