Breast Cancer: Surgery, Radiation and Chemotherapy

A breast cancer diagnosis often brings many questions and uncertainties. One of the most common concerns is understanding which treatment may be recommended and why some patients require surgery, while others may need radiation therapy, chemotherapy, or a combination of treatments.

The reality is that there is no single treatment approach for every patient. Breast cancer treatment is highly personalized and depends on factors such as the type of cancer, tumor size, stage of the disease, and other clinical considerations that help the oncology team develop the most appropriate treatment plan.

At BlueNetHospitals, our Oncology and Surgical Oncology specialists guide patients through every step of care, from diagnosis and treatment to long-term follow-up, providing evidence-based care tailored to each individual’s needs.

The most effective treatment plan depends on several factors, including:

• Tumor size and location
• Type and biological characteristics of the cancer
• Stage of the disease
• Whether lymph nodes are involved
• Overall health and medical history
• Personal preferences and treatment goals

In many cases, combining different treatment approaches helps reduce the risk of recurrence and improve long-term outcomes.

Surgery is often one of the most important treatments for early-stage and locally advanced breast cancer.

The primary goal is to remove the tumor and, when necessary, evaluate or treat nearby lymph nodes.

Also known as breast-conserving surgery, a lumpectomy removes the tumor along with a small margin of healthy tissue surrounding it.

This procedure is often recommended when:

• The tumor is relatively small.
• The cancer is localized.
• Most of the breast can be preserved.

In many cases, a lumpectomy is followed by radiation therapy to reduce the risk of recurrence.

A mastectomy involves the removal of all breast tissue affected by cancer.

This procedure may be recommended when:

• The tumor is large relative to breast size.
• Multiple areas of the breast are affected.
• Cancer has recurred.
• The patient chooses this option after discussing available treatments with the medical team.

Many women are candidates for breast reconstruction following a mastectomy or as part of a comprehensive treatment plan.

Depending on the individual case, reconstruction may be performed immediately during surgery or at a later stage of treatment.

Radiation therapy uses high-energy radiation to destroy cancer cells that may remain after surgery.

Its primary purpose is to reduce the risk of local recurrence.

Radiation therapy may be recommended after:

• Breast-conserving surgery
• Certain mastectomies
• Treatment involving affected lymph nodes

• Reduces the risk of cancer recurrence
• Complements surgical treatment
• Helps preserve the breast in many cases
• Improves local disease control

The duration and treatment schedule vary depending on each patient's specific diagnosis and treatment plan.

Chemotherapy uses medications that travel throughout the body to destroy cancer cells or stop their growth.

Unlike surgery or radiation therapy, chemotherapy is a systemic treatment, meaning it can target cancer cells that may have spread beyond the original tumor.

Known as neoadjuvant chemotherapy, this approach may be used to:

• Shrink the tumor before surgery
• Allow for less extensive surgery
• Evaluate how the cancer responds to treatment

Known as adjuvant chemotherapy, this treatment helps eliminate microscopic cancer cells that may remain after surgery.

Its primary goal is to lower the risk of recurrence.

When breast cancer has spread beyond the breast and nearby lymph nodes, chemotherapy may play an important role in controlling the disease and improving quality of life.

No.

Every breast cancer diagnosis is unique, and not all patients require all three treatments.

Some patients may achieve excellent outcomes with surgery and radiation therapy alone, while others may benefit from additional treatments such as chemotherapy, hormone therapy, targeted therapy, or immunotherapy.

Treatment decisions are made on an individual basis by a multidisciplinary team of specialists.

An accurate diagnosis and comprehensive evaluation are essential for determining the most appropriate treatment plan.

Oncology and Surgical Oncology specialists play a critical role in:

• Confirming the diagnosis
• Determining the stage of cancer
• Developing a personalized treatment strategy
• Explaining available treatment options
• Providing ongoing care throughout treatment and recovery

The best treatment depends on the type of breast cancer, the stage of the disease, and individual patient factors. Many patients benefit from a combination of treatments.

No. Some patients can be successfully treated with surgery, radiation therapy, hormone therapy, targeted therapy, or a combination of these treatments without chemotherapy.

Yes. When the tumor size and clinical situation allow, breast-conserving surgery followed by radiation therapy may be an option.

No. Radiation therapy itself is painless. Some side effects may develop gradually during treatment, depending on the treatment area and individual response.

Breast reconstruction may be performed during the same surgery as a mastectomy or at a later stage, depending on the patient's treatment plan and medical condition.
