Over the past 30 years, treatment of breast cancer has greatly improved due to lessons learned through clinical trials.
Clinical trials test the safety and benefits of new treatments, diagnostic methods and screening tests. People volunteer to take part in these research studies. Whether a new therapy or test becomes part of standard treatment (or diagnosis or screening) for breast cancer depends largely on clinical trial results. For example, clinical trials showed the benefit of hormone therapies and trastuzumab (Herceptin) in breast cancer treatment and these drugs are now part of standard care. Large randomized clinical trials are viewed as the best basis for making treatment guidelines.
Clinical trials take place across the country (and around the world) in many types of medical centers and hospitals. Often, trials are funded by a single agency like the National Cancer Institute (a government agency) and are carried out at the same time in many sites across the country. These are called cooperative group clinical trials, and they allow researchers to increase the number of people in a given study.
Dedicated physicians, researchers and other health professionals, as well as hospitals, medical research centers and funders are all key to clinical trials. However, most important are the participants. These are the people willing to join clinical trials that will help further the knowledge base that ultimately helps improve breast cancer care.
There are four main types of clinical trials that look at new breast cancer treatments:
If you have breast cancer, we encourage you to join a clinical trial. Clinical trials offer the chance to try new treatments and possibly benefit from them. Learning a new therapy is better than the standard treatment can also help others. And, as new therapies are developed, they can open doors to other drugs and procedures that may be even more effective.
Some people worry they will get a placebo instead of an effective treatment in a clinical trial. However, placebos are not used in metastatic breast cancer clinical trials and are not commonly used in other cancer trials. Your health care provider or the clinical research staff can tell you if there is a placebo in the study. Most often in a breast cancer treatment clinical trial, you will get either the new treatment or the standard treatment. So, even if you do not get the new drug (or other new therapy), your breast cancer will be treated just as it would if you were not in the trial. Sometimes in a non-metastatic cancer trial, you may get standard treatment plus a placebo rather than standard treatment plus a new treatment.
Where you live may be a factor in choosing to join a clinical trial. Some clinical trials are done only in one (or a few) medical centers, while others are done in many locations across the country. There may not be a clinical trial that is right for you in your local area.
The risks of a new treatment may not be fully understood, so there may be some unexpected side effects. Though testing keeps these risks as small as possible, all the side effects of a new treatment are often not revealed until after long-term testing and follow-up.
New treatment or tests being studied are usually paid for by the clinical trial. Out-of-pocket costs for most clinical trials are the same as those for standard treatment.
The Affordable Care Act (health care reform) now requires insurance companies to cover non-research, standard care costs related to a clinical trial (and not covered by the trial itself) plus any standard treatment given (learn more). Before enrolling in a clinical trial, talk with your insurance provider and find out exactly which costs are covered (and which are not). This ensures you do not have any unexpected costs, such as out-of-network fees.
Clinical trials at the Clinical Center of the National Institutes of Health (NIH) in Bethesda, Maryland are free of charge to those who are eligible to join and willing to get treatment at the center. For more information on these studies, visit the NIH clinical center website or call 1-800-4CANCER.
Though clinical trials usually study treatments, there are trials that focus on other areas of breast cancer, such as prevention and screening. These studies often look for women who have never had breast cancer to take part in the study.
There are also many clinical trials for breast cancer survivors who are not undergoing active treatment. These trials may include studies of long-term effects of breast cancer treatments and studies of the survival benefits of lifestyle behaviors (such as diet and exercise). Learn more about ways for survivors to get involved in breast cancer research.
All clinical trials have specific criteria for joining the study. For example, each trial will have a list of medical conditions that people must have (or not have) in order to join the study.
If you are newly diagnosed with breast cancer, you should consider joining a clinical trial before starting treatment. For most people with early breast cancer, treatment doesn’t start right after diagnosis. So, there is time to find a clinical trial that might meet your needs as part of your treatment options. Once you have begun standard treatment for early breast cancer, it can be difficult to join a clinical trial.
If you have a breast cancer recurrence, you should consider joining a clinical trial before treatment for recurrence begins or when your health care provider is considering changing treatments. If you are diagnosed with metastatic breast cancer, consider joining when your provider is considering changing treatments or before starting a new treatment.
Before you join a clinical trial, discuss the risks and benefits with your health care provider. There may be a research nurse or coordinator from the clinical trial who can give you more information about the study. See below for questions to ask your provider and/or the research staff about joining a clinical trial.
Talking with friends and family is also helpful during your decision-making process.
All clinical trials have guidelines (eligibility criteria) for who can join the study. These criteria vary from study to study and may be based on:
Most clinical trials are designed for select groups of people, so it is important to find a trial that fits your situation.
If you and your health care provider decide a clinical trial is a good option for you, your provider should put you in touch with a research nurse or coordinator from the trial. This person will guide you through the enrollment process.
Informed consent is the process of reviewing the risks, benefits and options for the study. It is required for all clinical trials. Before joining a trial, a research coordinator or nurse will go over the study protocol with you. The protocol describes in detail:
The research coordinator or nurse will answer any questions you have. Once you decide to join the study, you will be asked for your written permission. The document you sign is called a consent form and you will get a copy. This form includes the study protocol as well as the potential risks and benefits of the treatment or test.
Remember that being in a clinical trial is voluntary. You may leave the trial at any time, for any reason. Consenting and giving written permission to join the study does not force you to stay in the study.
Questions to Ask Your Doctor about Clinical TrialsTopic Card
Before joining a clinical trial, talk to the research coordinator, nurse or physician from the study. This person can answer your questions and discuss any concerns you may have. You may want to take a friend or family member with you to help ask questions, take notes and give you support. Also, you may wish to record the discussion so you can review it later.
It is a good idea to bring a list of questions and concerns. The following questions may be useful for your discussion.

Most clinical trials are funded by the National Cancer Institute (NCI), a part of the National Institutes of Health (NIH). NCI also sponsors groups that study the same cancer topic, such as the American College of Radiology Imaging Network. These groups include many hospitals, universities and physicians who work together to study certain cancer issues.
The Department of Defense and the Department of Veterans Affairs are other government sources of funding for clinical trials. Pharmaceutical and biotechnology companies and nonprofit organizations also sponsor clinical trials.
