Mastectomy is breast surgery that removes almost all or all breast tissue according to the treatment plan. It may be recommended for certain patients with breast cancer, such as when the tumor is large compared with breast size, when there are multiple areas of disease in the same breast, or when breast-conserving surgery is not suitable. Modern mastectomy techniques may help preserve the breast skin or nipple in carefully selected patients, and breast reconstruction may sometimes be performed during the same operation. This article explains the main types of mastectomy, what to expect, and how to care for yourself after surgery.
What is a mastectomy?
A mastectomy is an operation designed to control disease in the breast by removing breast tissue within an appropriate surgical margin. It is different from breast-conserving surgery, also called lumpectomy, which removes the tumor and a rim of surrounding tissue. In suitable patients, breast-conserving surgery followed by radiation therapy may provide survival outcomes similar to mastectomy. The best option depends on the cancer characteristics, breast size, treatment plan, and patient preference.
Main types of mastectomy
· Total or Simple Mastectomy: Removal of the whole breast, including the nipple and areola, without full removal of the axillary lymph nodes. Sentinel lymph node biopsy may still be performed when indicated.
· Modified Radical Mastectomy: Removal of the whole breast together with axillary lymph node dissection. This may be recommended when there is an indication to remove lymph nodes in the armpit.
· Skin-Sparing Mastectomy: Removal of breast tissue and the nipple-areola complex while preserving as much breast skin as possible. This technique is often used when breast reconstruction is planned.
· Nipple-Sparing Mastectomy: Removal of breast tissue while preserving the skin, nipple, and areola. It is suitable only for carefully selected patients whose disease does not involve the nipple or tissue beneath the nipple.
Who may be suitable for mastectomy?
Mastectomy may be considered for patients with a large tumor relative to breast size, multiple disease areas in the same breast, limitations to radiation therapy, a history of previous radiation to the breast area, or for patients who choose this approach after receiving full information. Suitability must be assessed individually by the breast surgeon and multidisciplinary team.
Preparation and what happens during surgery
Before surgery, the team will review your general health, biopsy results, imaging findings, lymph-node plan, and whether breast reconstruction is possible or appropriate. Mastectomy is usually performed under general anesthesia. The duration of surgery depends on the type of mastectomy and whether reconstruction is done at the same time. A temporary drain may be placed to remove fluid from the surgical area.
Self-care after surgery
· Care for the wound and drain according to the nursing team’s instructions.
· Start appropriate arm and shoulder exercises as advised to reduce stiffness.
· Avoid heavy lifting or strenuous activity during the early recovery period.
· Watch for warning signs such as fever, increasing redness or swelling, worsening pain, or unusually large amounts of fluid or bleeding, and contact the hospital if these occur.
· Pay attention to emotional recovery. Losing a breast can affect body image and confidence. Speaking with the care team, family, or patient-support groups may help.
Breast reconstruction after mastectomy
Some patients may choose breast reconstruction, either at the same time as cancer surgery, called immediate reconstruction, or at a later stage, called delayed reconstruction. Reconstruction may use an implant, the patient’s own tissue, or a combination. The decision should take into account the need for radiation therapy, medical conditions, tissue quality, and the patient’s goals.
Frequently Asked Questions (FAQ)
Is mastectomy better than breast-conserving surgery?
Not always. In suitable patients, breast-conserving surgery with radiation therapy may offer survival outcomes similar to mastectomy. The choice should be based on the disease pattern and the patient’s preferences after discussion with the medical team.
Will I need radiation therapy after mastectomy?
Some patients still need radiation after mastectomy, for example when the tumor is large, lymph nodes are involved, surgical margins or other risk factors are present. The doctor will assess this individually.
Can breast reconstruction be done at the same time?
Yes, in selected patients. Some patients are better suited to delayed reconstruction, especially when radiation therapy is planned.
How long does recovery take?
Many patients gradually return to daily activities within a few weeks. Recovery may take about 4-6 weeks or longer depending on the type of surgery, whether reconstruction is performed, and the patient’s overall health.
Does mastectomy guarantee that breast cancer will never come back?
No. Mastectomy reduces local disease risk but cannot guarantee zero recurrence. Regular follow-up according to the doctor’s plan remains important.
