The first-line treatment for breast cancer depends on many factors, including the type of breast cancer, its stage, a person’s overall health, and their preferences.
For people with breast cancer, knowing which treatment options doctors might recommend first is essential. This way, people can make informed decisions.
This article provides an overview of the first-line treatment options for breast cancer. It also looks at factors that affect treatment decisions and provides tips on how to choose the best treatment option.
Some people may undergo systemic therapy before surgery.
For those with metastatic breast cancer that has spread to other areas of the body, the
It is important to note that a person’s treatment plan will depend on many factors and can vary based on a person’s individual situation.
Lymph node biopsies may also help determine if the cancer has spread.

Hormone receptor-positive breast cancers rely on hormones to grow.
Hormone therapy, which includes tamoxifen and aromatase inhibitors,
Some breast cancers have specific characteristics that certain drugs can target. For example, targeted therapies
Some examples of targeted therapies used for hormone receptor-positive breast cancer include:
- CDK4/6 inhibitors: Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors,
such asribociclib, palbociclib, and abemaciclib, are targeted therapies that work by blocking the activity of specific proteins involved in cell division. These inhibitors can slow down cancer cell growth and delay disease progression.
- Everolimus: This targeted therapy
inhibitsa protein called mTOR, which regulates cell growth. When combined with an aromatase inhibitor, everolimus can delay disease progression in some instances of hormone receptor-positive, HER2-negative advanced breast cancer.

Chemotherapy uses drugs to
Doctors may administer this before surgery (neoadjuvant chemotherapy) to shrink the tumor or after surgery (adjuvant chemotherapy) to target any remaining cancer cells.

Radiation therapy, or radiotherapy, is a localized treatment that uses high energy radiation beams to target and damage cancer cells.
The goal is to kill or damage cancer cells in a specific area while minimizing harm to surrounding healthy tissue.
Doctors may use this as a stand-alone curative treatment or to either shrink tumors before surgery (neoadjuvant) or eliminate any remaining cancer cells after surgery (adjuvant).
- External beam radiation: This involves aiming radiation beams at the tumor site from outside the body using a machine called a linear accelerator.
- Internal radiation (brachytherapy): In some cases, small radioactive sources are placed inside the body temporarily or permanently to deliver radiation directly to the tumor site.

Several factors influence the type of treatment a person needs for breast cancer. Oncologists consider these factors to develop an
Here are the key factors that affect treatment decisions:
- Type and stage of breast cancer: Different types and stages of breast cancer require different treatment approaches.
- Tumor characteristics: Tumor characteristics include
hormone receptorstatus, HER2/neu status, and other molecular markers. These characteristics determine whether hormone therapy, targeted therapies, or other treatments are appropriate.
- Lymph node involvement: Whether cancer has spread to nearby lymph nodes is an important consideration. Lymph node involvement can influence decisions about surgery, radiation, and systemic therapies.
- Presence of metastasis: If breast cancer has spread to other parts of the body, the treatment approach shifts to focus on controlling the disease and managing symptoms.
Managing side effects is an essential aspect of breast cancer treatment, as it helps improve a person’s quality of life and overall well-being during and after therapy.
- Pain management: Pain can be a common side effect of surgery, chemotherapy, and radiation therapy. Pain medication, both over-the-counter and prescription, can help manage pain effectively. Alternative therapies such as acupuncture, massage, and relaxation techniques may relieve pain.
- Nausea and vomiting: Chemotherapy can cause nausea and vomiting. Anti-nausea medications, lifestyle adjustments — such as eating small, frequent meals — and dietary changes may help manage these symptoms.
- Fatigue: Cancer treatment often leads to fatigue. Rest and sleep are important, and moderate exercise under medical guidance can help alleviate fatigue. Managing stress and anxiety can contribute to better energy levels.
Choosing the best treatment approach for breast cancer involves carefully considering various factors.
When making treatment decisions, people can consider the following:
- discussing treatment options and their potential outcomes with their healthcare team
- seeking a
second opinionfrom another qualified oncologist to ensure they have explored different perspectives on the treatment plan
- clarifying treatment goals, whether they are focused on curing the cancer, managing symptoms, or prolonging life
- understanding the duration of each treatment option and how it fits into a person’s schedule and responsibilities
Questions to ask the doctor
Some questions people might want to ask their doctor include:
- What is the goal of each treatment option?
- What are the potential risks and side effects of each treatment?
- How likely are these side effects, and how can they be managed?
- What are the potential benefits of each treatment?
- What are the expected outcomes of each treatment option regarding survival and recurrence rates?
First-line treatment for breast cancer will depend on a variety of factors, such as the type and stage of breast cancer and a person’s overall health.
Choosing the best first-line treatment for breast cancer can be challenging. Knowing all of the options empowers people to work with their healthcare team to make the best decision for their situation.
