Breast-conserving surgery (lumpectomy)

This surgical approach involves removing only the tumor from the breast while preserving the rest of the breast tissue. It is usually recommended for patients with smaller tumors and is often followed by radiation therapy to target any remaining cancer cells. Lumpectomy allows women to retain their breast shape and offers excellent cosmetic outcomes.

Mastectomy (single or double)

Mastectomy involves the complete removal of the breast tissue. It is generally recommended for patients with large tumors, multiple tumors, or those who prefer a more aggressive surgical option. There are two types of mastectomy:

  • Unilateral Mastectomy: In this procedure, only the affected breast is removed, while the healthy breast remains unaffected.
  • Bilateral Mastectomy: This involves the removal of both breasts, even if cancer is present in only one breast. Some patients choose bilateral mastectomy as a preventive measure if they have a high risk of developing breast cancer in the healthy breast.

Sentinel Lymph Node Biopsy

Breast cancer often spreads to the nearby lymph nodes, making it essential to check whether the cancer has spread beyond the breast. A sentinel lymph node biopsy helps determine the involvement of lymph nodes. It involves the removal and examination of the first few lymph nodes to which the cancer cells are most likely to spread. This procedure helps determine the staging of cancer and influences further treatment decisions.

Reconstructive Surgery

Reconstructive surgery is an option for patients who have undergone mastectomy and would like to restore the appearance of their breasts. There are various techniques for breast reconstruction, including implants and tissue flap reconstruction. Implants involve the use of silicone or saline implants to recreate breast shape, while tissue flap reconstruction utilizes the patient’s own tissue to reconstruct the breast mound. The choice of reconstructive surgery depends on individual patient preferences, body shape, and overall health.
