Mastectomy

A mastectomy is the surgical removal of the entire breast. It may be recommended as part of breast cancer treatment or used to lower the risk of cancer for people with a high genetic risk.

Types of Mastectomies

Different types of mastectomies are available depending on your diagnosis, treatment plan, and personal preferences.

  • Total (Simple) Mastectomy

    Removes the entire breast, including the nipple and areola. Lymph nodes may be removed at the same time

    May be recommended if you:

  • Modified Radical Mastectomy

    Removes the entire breast and some or all of the lymph nodes under the arm (axillary lymph node dissection)

    May be recommended if you:

    • Cancer has spread to the nearby lymph nodes
    • You have inflammatory breast cancer
  • Skin-Sparing Mastectomy (SSM)

    Removes breast tissue, nipple, and often the areola, but keeps most of the natural breast skin

    May be recommended if you:

    • Commonly done when immediate reconstruction is planned
    • keeping the skin can help create a more natural-looking reconstruction
    • May not be recommended if:

    • Cancer involves or is close to the skin
    • You have been diagnosed with inflammatory breast cancer

    If needed, lymph node removal is typically done during the same surgery.

  • Nipple-Sparing Mastectomy (NSM)

    Removes breast tissue while preserving the nipple, areola, and most of the breast skin. Usually combined with immediate reconstruction

    May be recommended if you:

    • Have early-stage breast cancer best treated with a mastectomy
    • Have no cancer near or involving the nipple

    Keeping the nipple may help emotional well-being and give more natural looking results. However, NSM requires careful planning and surgical skill to ensure proper blood supply to the nipple.

    NSM is not available in all regions and may depend on your surgeon’s training and a plastic surgeon’s availability. When appropriately selected, the risk of cancer recurrence in the nipple area is low.

  • Double (Bilateral) Mastectomy

    Removes both breasts

    This is often done for people with:

    • A high genetic risk (e.g., BRCA1 or BRCA2 mutation carriers)
    • Cancer in both breasts
    • A personal decision to reduce future cancer risk
  • Radical Mastectomy

    Removes the entire breast, underlying chest wall muscles, and lymph nodes

    This extensive surgery is rarely performed today and is typically reserved for:

    • Advanced breast cancer that has spread to the chest muscles
    • Select recurrent cases where other treatment options are limited

Coverage for Prophylactic Mastectomy
In Canada, prophylactic mastectomy is publicly funded for individuals with a BRCA mutation or those considered high risk. However, eligibility criteria vary by province. Speak with your healthcare provider to determine your coverage options.

Coverage also varies for patients with cancer in one breast who wish to remove the other. In most cases, the decision is made between the patient and physician based on individual circumstances.
