This section discusses treatment for early and locally advanced breast cancers (stages I, II and III). These breast cancers include invasive ductal carcinomas and invasive lobular carcinomas. This section also discusses treatment for ductal carcinoma in situ (DCIS or stage 0).

If you’re looking for information about treatment for metastatic breast cancer, you can find it in ourMetastatic Breast Cancer section.

Starting Treatment for Early Breast Cancer or DCIS

Starting treatment for breast cancer can be overwhelming. You may be feeling anxious, scared or even in shock. Understanding your treatment options will help you be better informed as a patient. Your treatment options are based on your uniquebreast cancer diagnosis.

Each treatment has benefits and risks to consider along with your own values and lifestyle. It’s important to make thoughtful, informed decisions in partnership with your doctor. It’s also important tocomplete your breast cancer treatment plan. Those who complete their full course of treatment have a higher chance of survival.

Treatment for early breast cancer is designed to remove the cancer from the breast and kill any cancer cells that might still be in your body. Based on your specific breast cancer diagnosis, your doctor will recommend how to best treat your cancer. Your treatment will be based on your personal preferences and:  

• The biology of the tumor, including biomarkers (such ashormone receptor status andHER2 status) 
• Tumor profiling test results (for some estrogen receptor-positive (ER-positive) breast cancers) 
• Whether you have aBRCA1 orBRCA2 inherited gene mutation (for some HER2-negative breast cancers)
• Thestage of the breast cancer 
• Your overall health, age, menopausal status and other medical issues 

Types of treatment 

Early invasive breast cancer is cancer that has spread from the original location (milk ducts or lobules) into the nearby breast tissue and possibly into the lymph nodes.

Treatment for early invasive breast cancers includes some combination of surgery, radiation therapy and drug therapy (such as chemotherapy).

Treatment for breast cancer in men is similar to treatment for breast cancer in women.

Young women
With treatment, the chances of survival foryoung women with early breast cancer are good. However, young women may be concerned about loss of fertility (the ability to have a natural pregnancy) and other issues.

Breast cancer recurrence
Everyone who’s had breast cancer is at risk ofrecurrence (return of breast cancer), but risk varies greatly from person to person. Most people diagnosed with breast cancer will never have a recurrence. Talk with your doctor about your risk of recurrence.

Clinical trials
Over the past 40 years, breast cancer treatment has greatly improved due to findings from clinical trials. Research is ongoing to improve treatment for breast cancer. New therapies are being studied inclinical trials. The results of these studies will decide whether these therapies become part of the standard of care. After discussing the benefits and risks with your doctor, we encourage you to consider joining a clinical trial.

Emerging areas
Perhaps the most promising treatments under study for breast cancer are targeted therapies. Unlike many standard treatments, targeted therapies attack specific cancer cells and leave healthy cells alone. The hope is they may help limit side effects and improve survival. Learn about these and other breast cancer therapiesunder study.

Managing side effects is an important part of breast cancer care. All treatments for breast cancer have some side effects. The good news is most side effects can be managed and many can be prevented. Before any treatment begins, talk with your doctor about possible side effects and ways to deal with them.

Learn aboutpossible short-term side effects of treatment.

Supportive care(palliative care)
Supportive care is all the care given to improve your quality of life during and after treatment for breast cancer. It includes taking care of your physical,emotional, social and spiritual needs.

Talk with your doctor about how you’re coping during treatment. They care about your overall well-being and want to help. They may connect you to a mental health provider on your health care team, such as a social worker, for emotional support. They may also recommend you or your loved ones find a counselor orsupport group.
