Quick Answer

Breast cancer treatment is personalized. It may include local treatments such as surgery and radiation, and systemic treatments such as chemotherapy, hormone therapy, targeted therapy, and immunotherapy. The plan depends on stage, tumor biology, ER, PR, HER2 status, grade, lymph nodes, overall health, and patient preferences.

Treatment Pathway

Breast Cancer Treatment Overview

Breast cancer treatment often combines more than one approach. Some treatments focus on the breast and nearby lymph nodes, while others travel through the body to treat cancer cells that may have spread.

How breast cancer treatment is planned

A breast cancer treatment plan is usually based on cancer stage, tumor size, lymph node involvement, whether the cancer has spread, tumor grade, biomarker status, overall health, and patient goals. Biomarkers such as estrogen receptor, progesterone receptor, and HER2 can strongly influence treatment choices.

Treatment may be local, systemic, or both. Local treatments focus on the breast or nearby area. Systemic treatments travel through the bloodstream and can affect cancer cells throughout the body.

Local treatments: surgery and radiation

Surgery

Surgery removes cancer from the breast and may include lumpectomy, which removes the tumor and a margin of normal tissue, or mastectomy, which removes the breast. Lymph nodes may also be checked.

Radiation Therapy

Radiation therapy uses high-energy radiation to kill remaining cancer cells in a specific area. It is often used after breast-conserving surgery and may also be recommended in other situations.

Systemic treatments: medicines that travel through the body

Chemotherapy

Chemotherapy uses medicines that kill fast-growing cells or stop them from dividing. It may be given before surgery to shrink a tumor or after surgery to lower recurrence risk.

Hormone Therapy

Hormone therapy may be used for hormone receptor-positive breast cancer. It works by lowering hormone production or blocking hormone effects on cancer cells.

Targeted Therapy

Targeted therapy focuses on specific proteins or pathways that help cancer cells grow, divide, and spread. HER2-positive breast cancer is one example where targeted therapy may be used.

Immunotherapy

Immunotherapy helps the immune system recognize and attack cancer cells. It may be used for some breast cancers, including certain triple-negative breast cancers depending on biomarker testing and clinical context.

Neoadjuvant and adjuvant treatment

Treatment timing matters. Neoadjuvant treatment is given before the main treatment, often to shrink a tumor before surgery. Adjuvant treatment is given after surgery to lower the chance that cancer will return. Some patients may also receive maintenance or long-term therapy depending on tumor type and risk.

1

Before surgery

Possible neoadjuvant chemotherapy, targeted therapy, hormone therapy, or other treatment.

2

Local treatment

Surgery, and sometimes radiation therapy depending on the case.

3

After surgery

Possible adjuvant radiation, chemotherapy, hormone therapy, targeted therapy, or immunotherapy.

4

Follow-up care

Monitoring, survivorship planning, symptom management, and long-term support.

Treatment side effects and supportive care

Side effects depend on the treatment type and the individual person. They may include fatigue, pain, nausea, skin changes, hair loss, infection risk, lymphedema, menopause-related symptoms, emotional distress, fertility concerns, or long-term effects. Supportive care helps prevent, reduce, and manage symptoms during and after treatment.

Breast Cancer Treatment FAQ

Main treatment types include surgery, radiation therapy, chemotherapy, hormone therapy, targeted therapy, and immunotherapy. Many people receive a combination of treatments.

No. Treatment depends on cancer stage, type, grade, ER, PR, HER2 status, lymph nodes, whether cancer has spread, overall health, and patient goals.

Chemotherapy attacks rapidly dividing cells. Targeted therapy focuses on specific proteins or pathways that help cancer cells grow, divide, or spread.

Hormone therapy may be used when breast cancer cells have estrogen receptors or progesterone receptors. These cancers are called hormone receptor-positive.

Immunotherapy may be used for some breast cancers, including selected triple-negative breast cancers, depending on biomarkers and the clinical situation.
