Where the trials are

Listed sites in each state and territory. Choose one to show only the trials with a site there, and choose it again to show them all.

19 listed sites on this page do not say which state they are in, so the counts above are lower than the real number of sites in some states. The trials themselves are all listed below.

Trials for Breast Cancer

103 of 103 trials shown.

This Australian count is likely to be on the low side. It counts the trials this site files under this condition; the registry’s own search is broader and also returns closely related conditions, some of which have their own page here. If you are searching widely, check the registry as well — every trial below links to its own record.

Some Australian trials are registered only on the Australian New Zealand Clinical Trials Registry and are not shown here. Search them at Australian Clinical Trials.

Trials overseas

3,259 trials for this condition are open to new participants outside Australia, as ClinicalTrials.gov listed them on 11 October 2026. Voxsanity does not publish a page for any of them; the searches below reach them at the registry.

These overseas counts are likely too high. They come from the registry’s own search, which expands a condition name to related conditions, so some of the trials counted are for a different disease in the same family.

About Breast Cancer

The text below is reproduced exactly as its source published it. It has not been edited, shortened or rewritten.

What is breast cancer? Breast cancer is a cancer that starts in breast tissue. It happens when cells in the breast change and grow out of control. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Sometimes the cancer does not spread any further. This is called "in situ." If the cancer spreads outside the breast, the cancer is called "invasive." It may just spread to nearby tissues and lymph nodes. Or the cancer may metastasize (spread to other parts of the body) through the lymph system or the blood. Breast cancer is the second most common type of cancer in women in the United States. Rarely, it can also affect men. What are the types of breast cancer? There are different types of breast cancer. The types are based on which breast cells turn into cancer. The types include: - Ductal carcinoma, which begins in the cells of the ducts. This is the most common type. - Lobular carcinoma, which begins in the lobules. It is more often found in both breasts than other types of breast cancer. - Inflammatory breast cancer, in which cancer cells block lymph vessels in the skin of the breast. The breast becomes warm, red, and swollen. This is a rare type. - Paget's disease of the breast, which is a cancer involving the skin of the nipple. It usually also affects the darker skin around the nipple. It is also rare. What causes breast cancer? Breast cancer happens when there are changes in the genetic material (DNA). Often, the exact cause of these genetic changes is unknown. But sometimes these genetic changes are inherited, meaning that you are born with them. Breast cancer that is caused by inherited genetic changes is called hereditary breast cancer. There are also certain genetic changes that can raise your risk of breast cancer, including changes in the BRCA1 and BRCA2 genes. These two changes also raise your risk of ovarian and other cancers. Besides genetics, your lifestyle and the environment can affect your risk of breast cancer. Who is at risk for breast cancer? The factors that raise your risk of breast cancer include: - Older age - History of breast cancer or benign (noncancer) breast disease - Inherited risk of breast cancer, including having BRCA1 and BRCA2 gene changes - Dense breast tissue - A reproductive history that leads to more exposure to the estrogen hormone, including: - Menstruating at an early age - Being at an older age when you first gave birth or never having given birth - Starting menopause at a later age - Taking hormone therapy for meopause - Radiation therapy to the breast or chest - Obesity - Drinking alcohol What are the signs and symptoms of breast cancer? The signs and symptoms of breast cancer include - A new lump or thickening in or near the breast or in the armpit. - A change in the size or shape of the breast. - A dimple or puckering in the skin of the breast. It may look like the skin of an orange. - A nipple turned inward into the breast. - Nipple discharge other than breast milk. The discharge might happen suddenly, be bloody, or happen in only one breast. - Scaly, red, or swollen skin in the nipple area or the breast. - Pain in any area of the breast. How is breast cancer diagnosed? Your health care provider may use many tools to diagnose breast cancer and figure out which type you have: - A physical exam, including a clinical breast exam (CBE). This involves checking for any lumps or anything else that seems unusual with the breasts and armpits. - A medical history. - Imaging tests, such as a mammogram, an ultrasound, or an MRI. - Breast biopsy. - Blood chemistry tests, which measure different substances in the blood, including electrolytes, fats, proteins, glucose (sugar), and enzymes. Some of the specific blood chemistry tests include a basic metabolic panel (BMP), a comprehensive metabolic panel (CMP), and an electrolyte panel. If these tests show that you have breast cancer, you will have tests that study the cancer cells. These tests help your provider decide which treatment would be best for you. The tests may include: - Genetic tests for genetic changes such in the BRCA and TP53 genes. - HER2 test. HER2 is a protein involved with cell growth. It is on the outside of all breast cells. If your breast cancer cells have more HER2 than normal, they can grow more quickly and spread to other parts of the body. - An estrogen and progesterone receptor test. This test measures the amount of estrogen and progesterone (hormones) receptors in cancer tissue. If there are more receptors than normal, the cancer is called estrogen and/or progesterone receptor positive. This type of breast cancer may grow more quickly. Another step is staging the cancer. Staging involves doing tests to find out whether the cancer has spread within the breast or to other parts of the body. The tests may include other diagnostic imaging tests and a sentinel lymph node biopsy. This biopsy is done to see whether the cancer has spread to the lymph nodes. What are the treatments for breast cancer? Treatments for breast cancer include: - Surgery such as - A mastectomy, which removes the whole breast - A lumpectomy to remove the cancer and some normal tissue around it, but not the breast itself - Radiation therapy - Chemotherapy - Hormone therapy, which blocks cancer cells from getting the hormones they need to grow - Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells - Immunotherapy Can breast cancer be prevented? You may be able to help prevent breast cancer by making healthy lifestyle changes such as: - Staying at a healthy weight - Limiting alcohol use - Getting enough exercise - Limiting your exposure to estrogen by - Breastfeeding your babies if you can - Limiting hormone therapy If you are at high risk, your provider may suggest that you take certain medicines to lower the risk. Some women at very high risk may decide to get a mastectomy (of their healthy breasts) to prevent breast cancer. It's also important to get regular mammograms. They may be able to identify breast cancer in the early stages, when it is easier to treat. NIH: National Cancer Institute

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.

Questions to ask your doctor

General questions, the same on every condition page. Print this page to take them with you.

Is a clinical trial something I should consider at this point?
What would taking part involve week to week?
What are the risks, and what happens if I change my mind?
Would being in a trial change the care I get now?
Who would I see, and how far would I need to travel?
Are there costs, and is travel or time off work covered?
Can you refer me, or do I contact the trial site myself?

Is a medicine on the PBS?

Search the PBS on the Pharmaceutical Benefits Scheme's own website. Voxsanity does not publish PBS listings.
