Breast Cancer Treatments: An Informational Overview

Breast Cancer Treatments

Breast cancer treatments refer to the broad categories of medical approaches used to address breast cancer after diagnosis. These treatments vary depending on the stage of the disease, tumour characteristics, biological markers such as hormone receptor and HER2 status, and other individual factors assessed by healthcare professionals. Each category of treatment serves a different purpose in managing the condition, and treatment plans are designed by medical teams based on clinical evaluation.

Breast cancer treatment options fall into several major groups. These groups reflect different methods of managing cancer cells, limiting their growth, or addressing their presence in specific areas of the body. Understanding these categories can help individuals learn more about how breast cancer is approached in medical settings.

Surgery

Surgery is often used to remove cancerous tissue from the breast or surrounding areas. It plays a central role in the management of early-stage breast cancer and may also be part of treatment plans for more advanced disease.

Common surgical approaches include:

Breast-Conserving Surgery

This involves removing the tumour while preserving as much of the breast as possible. The goal is to remove the area containing cancer cells while retaining the surrounding breast structure.

Mastectomy

A mastectomy involves removing the entire breast. There are several types, ranging from simple mastectomy to more extensive procedures that remove additional surrounding tissues depending on the cancer’s characteristics.

Lymph Node Surgery

Lymph node involvement is an important part of breast cancer assessment. Surgeons may remove sentinel lymph nodes or axillary lymph nodes to examine whether cancer has spread beyond the breast.

These surgical approaches help determine how far the cancer has progressed and assist in forming a comprehensive care plan.

Radiation Therapy

Radiation therapy uses targeted energy to address cancerous cells in a specific area. It is commonly used after breast-conserving surgery and may also be used after mastectomy or in cases where cancer affects nearby lymph nodes.

Types of radiation approaches include:

External Beam Radiation

This is the most widely used method and delivers radiation from outside the body to the affected area.

Internal Radiation

Also known as brachytherapy, this involves placing small radiation sources inside or near the tumour site for a limited period.

Radiation therapy is typically localized, meaning it focuses on a specific region rather than the entire body.

Systemic Therapies

Systemic therapies circulate throughout the body. These may be used in early-stage or metastatic breast cancer, depending on clinical assessment. They target cancer cells that may be present in the breast, lymph nodes, or distant areas.

Chemotherapy

Chemotherapy uses medications that affect cell growth. These medications travel through the bloodstream and can reach cancer cells beyond the original tumour site. Chemotherapy may be given before surgery (neoadjuvant) or after surgery (adjuvant).

Hormone Therapy

Some breast cancers depend on hormones such as estrogen or progesterone to grow. Hormone therapy helps reduce or block the influence of these hormones on cancer cells. It is primarily used for hormone receptor-positive breast cancers.

Targeted Therapy

Targeted therapy focuses on specific biological features present in some breast cancers. For example, HER2-positive breast cancers may receive medications designed to interact with the HER2 protein. Different targeted therapies exist depending on tumour characteristics identified through biopsy.

Immunotherapy

Immunotherapy uses medications designed to support the body’s immune system as it interacts with cancer cells. It may be used for certain breast cancer types, including some triple-negative breast cancers. Immunotherapy eligibility is determined by studying tumour markers.

Systemic therapies vary based on factors such as tumour biology, receptor status, and medical team recommendations.

Neoadjuvant and Adjuvant Treatment

Breast cancer therapies may be given at different points in the treatment timeline:

Neoadjuvant Treatment

This refers to treatment given before surgery. It may be used to shrink a tumour, evaluate tumour responsiveness, or address cancer cells that may have spread beyond the breast.

Adjuvant Treatment

Adjuvant treatment is given after surgery to help address cancer cells that might remain in the body. This phase often includes radiation therapy, chemotherapy, hormone therapy, or targeted therapy depending on tumour characteristics.

These phases help ensure treatment is organized in a way that aligns with the cancer’s biology and the overall medical plan.

Treatment Planning and Monitoring

Breast cancer treatment is individualized. Medical teams consider:

Tumour size and location

Stage of disease

Hormone receptor and HER2 status

Lymph node involvement

General health factors

Other biological markers

Monitoring may include imaging, physical examinations, and laboratory tests to assess how the cancer responds over time. Treatment plans may change based on clinical findings.

Advanced and Metastatic Breast Cancer

For metastatic (stage IV) breast cancer, treatment focuses on systemic approaches that address cancer throughout the body. Medical teams may use ongoing therapies tailored to tumour biology, response patterns, and the individual’s overall health. Treatments for metastatic disease vary widely and may include combinations of hormonal, targeted, immune-based, or chemotherapy medications.

Clinical Research and Evolving Treatment Strategies

Breast cancer research continues to progress, providing more insight into tumour behaviour, biomarkers, and genetic patterns. Studies examine new treatment pathways, improved diagnostic tools, and therapies designed to target specific tumour characteristics. Research developments contribute to the ongoing refinement of medical approaches used by healthcare professionals.

Supportive Care

Supportive care includes services that help individuals manage the physical, emotional, and practical aspects of breast cancer. This may involve pain management, nutrition support, mental health resources, and other forms of care that address overall well-being. Supportive care is relevant at all stages of breast cancer and may be adapted based on individual needs.

Key Takeaways

Breast cancer treatment includes surgery, radiation therapy, chemotherapy, hormone therapy, targeted therapy, immunotherapy, and supportive care. Treatment plans are individualized according to tumour biology, stage, and medical assessment. Understanding these categories helps individuals become more informed about how breast cancer is managed in medical settings.
