The choice of treatment will depend on factors such as the type and stage of breast cancer, as well as the individual’s overall health and preferences.

According to the American Cancer Society, the survival rates for breast cancer vary depending on the stage at diagnosis. For example, the five-year relative survival rate for localized breast cancer is 99%, while the rate drops to 27% for breast cancer that has spread to distant organs.

It is essential for individuals diagnosed with breast cancer to work closely with their healthcare team to determine the most appropriate treatment plan tailored to their specific needs and circumstances.

Surgery: Types and Procedures

There are several types of surgery available for treating breast cancer, each with its own specific procedures and goals. Here is an overview of the common surgical options:

Lumpectomy

A lumpectomy, also known as breast-conserving surgery, involves removing the tumor and a small amount of surrounding tissue while preserving the breast. This procedure aims to remove the cancerous cells while maintaining the breast’s appearance. It is often followed by radiation therapy to ensure all cancer cells are destroyed.

Mastectomy

A mastectomy is the surgical removal of the entire breast, and it may be necessary if the cancer is large or if the patient prefers a more drastic approach. There are different types of mastectomy, including:

  • Simple or Total Mastectomy: Removal of the entire breast.
  • Modified Radical Mastectomy: Removal of the entire breast, some lymph nodes, and chest wall muscles.
  • Radical Mastectomy: Removal of the breast, lymph nodes, and chest muscles.

Lymph Node Removal

In some cases, lymph nodes in the armpit may be surgically removed to determine if cancer has spread beyond the breast. This procedure helps determine the stage of the cancer and guides further treatment decisions.

According to a study conducted by the American Cancer Society, approximately 310,000 women in the United States underwent breast cancer surgery in 2020. Surgical treatment remains one of the most effective ways to remove cancerous tissue and reduce the risk of recurrence.
