Early and locally advanced breast cancers are invasive breast cancers. However, they have not spread beyond the breast and nearby lymph nodes to other parts of the body (they are non-metastatic).
Early breast cancer is contained in the breast. Or, it has only spread to the lymph nodes in the underarm area. This term often describes stage I and stage II breast cancer.
In the U.S., most breast cancers are found at these early stages.
Locally advanced breast cancer has spread beyond the breast to the chest wall or the skin of the breast. Or, it has spread to many lymph nodes in the underarm area (axillary lymph nodes). Locally advanced breast cancer can also refer to a large tumor.
With treatment, people with early breast cancer usually have a very good prognosis.
For example, from 2009-2015 (most recent data available) :
With recent improvements in treatment, survival for women diagnosed today may be even higher.
However, prognosis for breast cancer depends on each person’s diagnosis and treatment.
Treatment for early breast cancer (including invasive ductal carcinoma and invasive lobular carcinoma) usually involves some combination of surgery, radiation therapy, chemotherapy, hormone therapy and/or HER2-targeted therapy.
Surgery is usually the first step in treating early breast cancer.
You may have a mastectomy (the entire breast is removed) or a lumpectomy (only the tumor and some surrounding tissue are removed).
With either type of surgery, some lymph nodes in the underarm area (axillary nodes) may be removed to find out whether the cancer has spread there.
Women who have a lumpectomy also have radiation therapy to the breast to get rid of any cancer cells that may remain. This lowers the chances of the cancer coming back (recurrence) .
Most women who have a mastectomy don’t need radiation therapy, if there's no cancer in the lymph nodes.
However, in some cases, radiation therapy is used after mastectomy to treat the chest wall, the axillary lymph nodes and/or the lymph nodes around the collarbone.
For a summary of research studies on mastectomy versus lumpectomy plus radiation therapy and overall survival in early breast cancer, visit the Breast Cancer Research Studies section.
For a summary of research studies on radiation therapy following mastectomy in women with invasive breast cancer, visit the Breast Cancer Research Studies section.
Most people have treatments after surgery to help prevent the breast cancer from coming back. It's not common to have surgery as the only treatment.
Some combination of chemotherapy, hormone therapy and/or HER2-targeted therapy almost always follows breast surgery.
These drug therapies travel throughout the body to help ensure the body is rid of cancer. They may be called systemic therapy or adjuvant therapy.
Some drug therapies are given by vein (through an IV) and some are pills.
Which treatments you will need after surgery depends on:
For women, whether you are pre- or postmenopausal can also play a role in your treatment options.
Women with lymph node-negative, hormone receptor-positive tumors larger than 0.5 cm should consider getting tumor profiling testing (such as Oncotype DX®) to see if chemotherapy is needed .

Neoadjuvant therapy is treatment given before surgery. Treatment can be chemotherapy, HER2-targeted therapy or hormone therapy. Neoadjuvant therapy may also be called preoperative therapy.
Some women with early breast cancer may have neoadjuvant therapy as a first treatment. Neoadjuvant therapy may shrink a tumor enough so a lumpectomy becomes an option instead of a mastectomy.
Treatment for locally advanced breast cancer usually begins with neoadjuvant therapy. Neoadjuvant therapy helps shrink the tumor(s) in the breast and lymph nodes so surgery can better remove all of the cancer.
Learn more about neoadjuvant therapy.
With neoadjuvant chemotherapy, all the chemotherapy to treat the breast cancer is usually given before surgery . If the tumor does not get smaller with the first combination of chemotherapy drugs, other combinations can be tried.
If your tumor is HER2-positive, you may get neoadjuvant trastuzumab (Herceptin) and neoadjuvant pertuzumab (Perjeta), but not at the same time as the chemotherapy drug doxorubicin (Adriamycin) .
Some postmenopausal women with hormone receptor-positive tumors may get neoadjuvant hormone therapy (usually with an aromatase inhibitor) instead of neoadjuvant chemotherapy .
In rare cases, if a locally advanced breast cancer does not respond to neoadjuvant chemotherapy, radiation therapy may be given before surgery .

If you have been diagnosed with early breast cancer, Susan G. Komen® has a series of Questions to Ask Your Doctor resources that may be helpful. For example, we have a Questions to Ask Your Doctor About Breast Cancer Surgery resource and a Questions to Ask Your Doctor About Hormone Therapy resource.
You can download and print these resources and take them with you to your next doctor appointment. There’s plenty of space to write down the answers to these questions, which you can refer to later.
There are other Questions to Ask Your Doctor resources on many different breast cancer topics you may wish to download. They are a nice tool for people recently diagnosed with breast cancer, who may be too overwhelmed to know where to begin to gather information.
Although the exact treatment for breast cancer varies from person to person, guidelines help ensure high-quality care. These guidelines are based on the latest research and agreement among experts.
The National Comprehensive Cancer Network (NCCN) and the American Society of Clinical Oncology (ASCO) are respected organizations that regularly review and update their guidelines.
In addition, the National Cancer Institute (NCI) has treatment overviews.
Talk with your health care providers about which treatment guidelines they use. Since there’s often a lag time between the latest research and guideline updates, most providers prefer to base their treatment on the latest research.
You play an active role in making treatment decisions by understanding your breast cancer diagnosis, your treatment options and possible side effects.
Together, you and your health care provider can choose treatments that fit your values and lifestyle.
In 2013, the Health and Medicine Division of the National Academy of Sciences (formerly the Institutes of Medicine) released a set of recommendations (below) on improving cancer care in the U.S. The report, Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis recommended improvements to fix shortcomings that add cost and burden to cancer care. Susan G. Komen® was one of 13 organizations that sponsored this study.
The report identified key ways to improve quality of care:

Research is ongoing to improve all areas of treatment for breast cancer.
New therapies are being studied in clinical trials. The results of these studies will decide whether these therapies will become part of standard care.
After discussing the benefits and risks with your health care provider, we encourage you to consider joining a clinical trial.
BreastCancerTrials.org in collaboration with Susan G. Komen® offers a custom matching service to help you find clinical trials that fit your needs.
If you're newly diagnosed with early or locally advanced breast cancer, consider joining a clinical trial before starting treatment. For most people, treatment doesn’t usually start right after you’ve been diagnosed. So, there’s time to look for a clinical trial that you’re eligible for and fits your needs.
Once you’ve begun standard treatment for early or locally advanced breast cancer, it can be difficult to join a clinical trial.
