Comprehensive Guide to Breast Cancer Treatment Options and Therapies – Surgery, Radiation, Chemotherapy, Hormone Therapy, Immunotherapy, and Integrative Therapies

Overview of Breast Cancer Treatment

When it comes to treating breast cancer, there are several options available to patients depending on the stage and type of cancer. The main treatment modalities include surgery, radiation therapy, chemotherapy, hormone therapy, targeted therapy, immunotherapy, and integrative therapies.


One of the primary treatment options for breast cancer is surgery. There are different types of surgeries available depending on the extent of the cancer and whether the patient wants breast conservation or a full mastectomy. Common surgical procedures include:

  • Lumpectomy: A surgery to remove only the tumor and a margin of surrounding tissue.
  • Mastectomy: Removal of the entire breast.
  • Axillary Lymph Node Dissection: Removal of lymph nodes in the armpit to determine if cancer has spread.

It is important for patients to discuss with their healthcare team the best surgical option for their specific situation.

Radiation Therapy

Radiation therapy is often used after surgery to kill any remaining cancer cells. There are different types of radiation therapy:

  • External Beam: Radiation delivered from a machine outside the body.
  • Internal Radiation: Radiation delivered through implants placed near the tumor.

Side effects of radiation therapy may include skin changes, fatigue, and potential long-term effects on the heart and lungs.


Chemotherapy involves the use of drugs to kill cancer cells. There are different types of chemotherapy drugs available, and the administration can be intravenously, orally, or directly into the affected area. Common side effects of chemotherapy include hair loss, nausea, and increased risk of infection.

National Cancer Institute provides detailed information on chemotherapy options and effectiveness.

This section provides an overview of the main treatment modalities for breast cancer. Next sections will delve deeper into each treatment option and their implications for patients.

According to the, an estimated 281,550 new cases of breast cancer will be diagnosed in the United States in 2021, underlining the importance of understanding these treatment options.

Surgery: Lumpectomy, Mastectomy, Axillary Lymph Node Dissection

When it comes to breast cancer treatment, surgery is often one of the first options considered. There are several types of surgeries available, depending on the stage and characteristics of the cancer. The most common surgical procedures for breast cancer include:


Lumpectomy, also known as breast-conserving surgery, involves removing the tumor along with a small margin of surrounding healthy tissue. It is often recommended for early-stage breast cancer where the tumor is small and localized. This procedure aims to preserve as much of the breast tissue as possible while ensuring that the cancer is completely removed.


Mastectomy is a surgical procedure that involves removing the entire breast. There are different types of mastectomies, including:

  • Simple or Total Mastectomy: Removes the entire breast but not the lymph nodes.
  • Modified Radical Mastectomy: Removes the entire breast and some lymph nodes under the arm.
  • Radical Mastectomy: Removes the entire breast, lymph nodes, and chest wall muscles under the breast.

The choice of mastectomy type depends on various factors, such as the extent of the cancer and the patient’s preferences.

Axillary Lymph Node Dissection

Axillary lymph node dissection is a procedure that involves removing lymph nodes from the armpit area (axilla) to determine if cancer has spread beyond the breast. This procedure helps in staging the cancer and determining the need for further treatment, such as radiation therapy or chemotherapy.

It’s essential to discuss the surgical options with a healthcare provider to determine the most suitable approach based on the individual’s specific case.
