Breast cancer is a malignant disease where early detection via screening improves outcomes. Treatment commonly starts with surgery (lumpectomy or mastectomy), with sentinel lymph node biopsy used for staging. Radiation, chemotherapy, hormone therapy (e.g., tamoxifen or aromatase inhibitors), and targeted drugs are used based on tumor subtype. Lifestyle measures and personalized screening reduce risk and detect disease earlier.

What is breast cancer?

Breast cancer is a malignant growth that arises in breast tissue and can spread (metastasize) to other organs. Early detection improves treatment choices and outcomes.

Prevention and early detection

Screening mammography remains the primary tool for finding many early breast cancers. Routine breast self-exam is no longer universally recommended as a formal screening test; instead, clinicians advise breast awareness (knowing your own breast pattern and reporting changes) and regular clinical exams when indicated. Guidelines for when to start and how often to screen vary, so discuss a personalized plan with your clinician.

Healthy habits can reduce risk: limiting alcohol, maintaining a healthy weight, staying physically active, and breastfeeding when possible are associated with lower breast cancer risk.

Main surgical options

Surgery to remove the tumor is usually the first local treatment. Common options now include:

  • Breast-conserving surgery (lumpectomy/segmental mastectomy) - removes the tumor and a margin of healthy tissue; usually followed by radiation to lower local recurrence risk.
  • Simple (total) mastectomy - entire breast tissue removed; may be chosen for multicentric disease or patient preference.
  • Modified radical mastectomy - breast and axillary lymph nodes removed, but chest muscles preserved.
  • Radical mastectomy - removal of breast, axillary nodes, and chest muscles; now rarely performed except in unusual situations.
Sentinel lymph node biopsy is routinely used to stage the axilla in early disease, often avoiding full axillary dissection and its long-term lymphedema risk.

Reconstruction (immediate or delayed) is an option after mastectomy and should be discussed with a surgical team.

Systemic and radiation treatments

  • Radiation therapy commonly follows breast-conserving surgery and may be recommended after mastectomy for larger tumors or nodal involvement.
  • Chemotherapy can be given before surgery (neoadjuvant) to shrink tumors or after surgery (adjuvant) to reduce recurrence risk.
  • Hormone (endocrine) therapy treats hormone receptor-positive tumors. Tamoxifen is commonly used, especially in premenopausal women; aromatase inhibitors are frequently used in postmenopausal women.
  • Targeted therapies treat specific tumor subtypes. For HER2-positive cancers, anti-HER2 drugs are standard. Newer antibody-drug conjugates and some immunotherapies are available for selected advanced or high-risk subtypes.
Treatment plans combine local and systemic approaches based on tumor biology (hormone receptor and HER2 status), stage, genetic findings, and patient preferences.

Key takeaways

Early detection expands treatment options. Surgery remains central for most early cancers, paired with radiation, systemic chemotherapy, hormone therapy, or targeted drugs as appropriate. Discuss screening, reconstruction, and a personalized treatment plan with a multidisciplinary team.

FAQs about Breast Cancer Treatment Options

What are the major treatment choices for early breast cancer?
Surgery (breast-conserving surgery or mastectomy) is the primary local treatment. It is often combined with radiation, and systemic therapies (chemotherapy, hormone therapy, targeted therapy) are added based on tumor stage and biology.
Is a lumpectomy as effective as a mastectomy?
For many early-stage cancers, breast-conserving surgery followed by radiation offers survival outcomes similar to mastectomy. The choice depends on tumor size, location, genetic factors, and personal preference.
When is tamoxifen used?
Tamoxifen is an endocrine therapy commonly used for estrogen receptor-positive breast cancer, especially in premenopausal women. Postmenopausal patients are often treated with aromatase inhibitors.
What is sentinel lymph node biopsy?
Sentinel lymph node biopsy identifies the first draining lymph node(s) from the tumor. If those nodes are cancer-free, patients can often avoid more extensive axillary dissection and lower lymphedema risk.
How can I lower my breast cancer risk?
Maintain a healthy weight, be physically active, limit alcohol, consider breastfeeding when possible, and follow a screening plan tailored to your risk profile.
