The treatment options for breast cancer depend on the type and stage of cancer, as well as individual patient factors. Here are the main treatment modalities:

1. Surgery

• Lumpectomy: Also known as breast-conserving surgery, it involves removing the tumor and a small margin of surrounding tissue while preserving most of the breast.

• Mastectomy: Involves removing the entire breast. Types include total mastectomy (simple mastectomy), modified radical mastectomy, and radical mastectomy.

• Sentinel Lymph Node Biopsy and Axillary Lymph Node Dissection: These procedures involve removing lymph nodes to check for the spread of cancer.

2. Radiation Therapy

• External Beam Radiation: The most common type, which uses high-energy rays to target and kill cancer cells in the breast.

• Brachytherapy: Involves placing radioactive seeds or pellets inside the breast tissue near the tumor site.

3. Chemotherapy

• Neoadjuvant Chemotherapy: Given before surgery to shrink tumors.
• Adjuvant Chemotherapy: Given after surgery to eliminate remaining cancer cells and reduce the risk of recurrence.

4. Hormone (Endocrine) Therapy

• Tamoxifen: A selective estrogen receptor modulator (SERM) used for both premenopausal and postmenopausal women.
• Aromatase Inhibitors: Drugs such as anastrozole, letrozole, and exemestane, used primarily in postmenopausal women.

5. Targeted Therapy

• HER2-Targeted Therapies: Trastuzumab (Herceptin), pertuzumab (Perjeta), and other drugs target the HER2 protein on cancer cells.
• CDK4/6 Inhibitors: Such as palbociclib (Ibrance) and ribociclib (Kisqali), used in combination with hormone therapy.

6. Immunotherapy

• Checkpoint Inhibitors: Such as pembrolizumab (Keytruda), used for certain types of triple-negative breast cancer.
• Sources: American Cancer Society, Mayo Clinic

7. Clinical Trials

• Description: Participation in clinical trials can provide access to new treatments and therapies that are not yet widely available.

Personalized Treatment Plans

The choice of treatment depends on several factors including the type and stage of cancer, hormone receptor status, HER2 status, patient’s overall health, and personal preferences. Treatment often involves a combination of therapies tailored to the individual patient’s needs.
