Oncoplastic Breast-Conserving Surgery vs Mastectomy

Understanding Breast Cancer Surgery in Sydney

When you receive a breast cancer diagnosis, one of the first questions is: Can I keep my breast, or do I need a mastectomy?

Modern breast surgery offers safe ways to remove cancer while maintaining a natural look. Your doctor will discuss what’s best for your body, considering the size and location of the tumour, your breast size, and personal preferences.

Breast cancer surgery isn’t just about removing cancer.  It’s also about preserving confidence, comfort, and appearance. Knowing your options helps you make informed decisions and feel more in control.

Oncoplastic Breast-Conserving Surgery (OBCS)

Oncoplastic breast surgery removes the cancer while keeping most of your breast. It combines cancer removal with reshaping techniques, so your breast looks natural.

Small Tumour Surgery (Type 1)

  • Removes a small area of tissue (usually less than 20% of the breast)

  • Breast is reshaped using your own tissue

  • Short recovery time, often back to normal activities quickly

Larger Tumour Surgery (Type 2)

  • Removes a larger area of tissue (20–50% of the breast)

  • Combines with a breast lift or reduction for symmetry

  • Usually requires slightly longer recovery, but preserves the breast

OBCS is a great option for patients who want to maintain their breast shape while ensuring complete cancer removal. Many patients are pleasantly surprised by the natural appearance after surgery.

Mastectomy Options in Sydney

Sometimes, removing the entire breast is the safest choice. Advances in surgical techniques allow reconstruction at the same time, preserving shape and appearance.

Skin-Sparing Mastectomy

  • Preserves most of the breast skin

  • Supports immediate reconstruction

  • Scars are smaller and placed strategically

Nipple-Sparing Mastectomy

  • Preserves the nipple when safe to do so

  • Works well with immediate reconstruction

  • Helps maintain a natural look

Choosing the right mastectomy depends on tumour size, location, genetics, and your preferences. Your doctor will guide you through options that balance safety and appearance.

Breast Reconstruction After Surgery

Reconstruction restores the breast shape and can be done using implants or your own tissue.

Implant Options

  • Pre-pectoral implants: sit on top of the chest muscle, avoiding movement-related distortion

  • Sub-pectoral implants: sit under the chest muscle for extra coverage

Using Your Own Tissue

  • Latissimus Dorsi flap: tissue from the back is used to rebuild the breast

  • Fat grafting (lipofilling): transfers small amounts of fat to improve shape and smooth contours

Reconstruction is usually planned before surgery to ensure the best outcome. Many patients return to normal life faster than expected with modern techniques.

Choosing the Right Surgery for You

Your treatment is guided by a multidisciplinary team (MDT) including surgeons, oncologists, and radiologists.  Your surgical plan may also include sentinel lymph node biopsy to assess whether breast cancer cells have spread to nearby lymph nodes.

 Factors considered include:

  • Tumour size, type, and location

  • Breast size and shape

  • Patient preferences and lifestyle

  • Need for reconstruction and cosmetic outcomes

Both oncoplastic breast-conserving surgery and mastectomy are safe. The choice is personal, balancing oncologic safety with appearance and comfort.

After surgery, follow-up care focuses on:

  • Early shoulder mobility exercises

  • Scar care and monitoring

  • Preventing swelling or lymphoedema

  • Pathology results to guide further treatment

Recovering from Breast Cancer Surgery

Recovery depends on the type of surgery, but most patients return to normal activities within a few weeks. Pain is usually manageable with medication, and scars fade over time.

Regular check-ups ensure your treatment was successful, and support services can help you adjust physically and emotionally. Patients often report improved confidence and peace of mind after surgery.
