How these figures are counted
  • Trials on record is every trial tagged to this condition at any stage whose registry record agrees it is for this condition, except those withdrawn before starting or terminated early. Most are completed rather than ongoing, so this is a measure of research history, not of current activity. It is also smaller than the sitewide "trials tracked" figure, which does include withdrawn and terminated trials.
  • Recruiting now counts only trials whose registry status is "Recruiting" and whose registry record agrees they are for this condition. Trials listed as not yet recruiting or enrolling by invitation are excluded, so this understates how many may open to new participants soon.
  • Recruiting with an AU site counts trials counted under "Recruiting now" that list at least one Australian site. A site being listed does not mean it is currently enrolling, and Australian trials registered only on ANZCTR are not counted yet, so this understates local availability.
  • Phase 3 trials counts trials counted under "Recruiting now" that are at Phase 3.

Understanding Breast Cancer

Breast cancer is a condition where cells in the breast begin to grow in an uncontrolled way, forming a lump or tumour. Normally, cells in the body grow, divide, and die in an orderly way, but cancer cells do not follow these rules. Breast cancer most commonly starts in the ducts or lobules of the breast. There are several different types of breast cancer, and they can behave differently from one another, which is why doctors run a number of tests after a diagnosis to understand exactly what type is present and how far it may have spread.

In Australia, breast cancer is the most commonly diagnosed cancer among women, with around 20,000 Australians diagnosed each year. While it is far less common in men, it does occur. The risk of being diagnosed increases with age, though it can affect younger people too. Thanks to screening programs like BreastScreen Australia and advances in treatment, survival rates have improved significantly over recent decades, and many people go on to live full lives after a diagnosis.

Treatment for breast cancer in Australia is generally overseen by a team of specialists and is tailored to the individual, taking into account the type and stage of the cancer, as well as the person's overall health and personal circumstances. Common treatments can include surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy, and these are often used in combination. Your medical team will explain the options that are relevant to your specific situation. Support services are also available through organisations like the Cancer Council Australia, which can provide information and connect you with practical and emotional support.

PBS-subsidised medicines for Breast Cancer

24 medicines listed on the PBS for Breast Cancer. Filter by authority type, or open the full table below.

What the authority types mean Unrestricted: no clinical criteria; a doctor can prescribe it on the PBS for any appropriate use. Restricted benefit: subsidised only for the specific conditions or uses set out by the PBS. Streamlined authority: restricted, but the doctor does not need prior approval; they record a streamlined authority code confirming you meet the criteria. Authority required: restricted, and the doctor must get prior approval from Services Australia (by phone or online) before it is subsidised. Source: Pharmaceutical Benefits Scheme (pbs.gov.au).

The pills count listings, not medicines. A medicine subsidised for more than one indication has a row for each, so these four add up to 35 across 24 medicines. The figure above counts each medicine once; these never can.

Full PBS medicines table 24 medicines

These medicines are listed on the Pharmaceutical Benefits Scheme (PBS) for the specific indications shown. A listing does not mean a medicine is right for you; your doctor decides what is appropriate. The Government price column is the PBS-determined price the Government pays the pharmacy for the item — it is not what you pay at the counter. Most patients pay only the standard co-payment, up to AU$25.00 per script (general) or AU$7.70 (concession or Safety Net) in 2026, with the Australian Government subsidising the rest. Confirm the current amount with your pharmacist.

Medicine supply notices from the TGA

The Therapeutic Goods Administration currently reports a shortage of 1 of the 24 PBS-subsidised medicines listed above for Breast Cancer: Vinorelbine.

The TGA also expects a shortage of one of the 24 PBS-subsidised medicines listed above. This is a supplier's forecast of a shortage that has not started yet, not a shortage happening now:Medroxyprogesterone.

The TGA also has a discontinuation on record for 2 of the 24 PBS-subsidised medicines listed above. A discontinuation applies to a particular registered product — one brand, strength and dose form — so other brands or strengths of the same medicine may be unaffected:Goserelin, Trastuzumab.

A shortage does not usually mean a medicine is unavailable everywhere. It often affects particular brands, strengths or pack sizes and not others. This is national information: the TGA does not publish stock levels for individual pharmacies, states or territories, and neither do we. If one of these is a medicine you take, your pharmacist can tell you what is available and discuss alternatives with your prescriber. Do not stop or change how you take a medicine without speaking to your doctor or pharmacist.

How these counts work: we match the active-ingredient names in the TGA's register against the PBS medicines listed above, and count only medicines that appear in both. Each count above is out of that same list of 24. They therefore understate rather than overstate. A medicine that the PBS does not subsidise for Breast Cancer, one the TGA lists under an ingredient name we cannot match, and one used for Breast Cancer but subsidised under a different indication, are all missing from these counts. The presence of a medicine here is a co-occurrence — it says the TGA's record and the PBS listing are both real, not why the shortage happened. The TGA does not publish a reason for shortage, so we do not state one. A shortage the TGA has recorded as resolved is deliberately not counted here: it is not information about supply today.

Clinical trials for Breast Cancer

Showing 1424 of 1424 trials

6,171 trials are on record for Breast Cancer and 1,424 are listed here. The list carries trials we can show a plain English summary for: every trial open or about to open to new participants, plus concluded trials that have published their results. The great majority of the difference is research that finished without publishing a results summary, so there is nothing to read and nothing to join. A smaller part is trials that are open now but whose plain English summary has not been written yet. Nothing is being withheld: the larger figure counts research history, this list counts what is useful to read today.

The trial catalogue is checked nightly, but 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.

Common questions about Breast Cancer

The same six questions on every condition page, answered from the figures on this page at the moment it was built. Not medical advice.

Is there a clinical trial for Breast Cancer currently recruiting in Australia?

Yes. 39 of the 1042 clinical trials recruiting for Breast Cancer list at least one Australian site. That counts trials counted under "Recruiting now" that list at least one Australian site. A site being listed does not mean it is currently enrolling, and Australian trials registered only on ANZCTR are not counted yet, so this understates local availability.

Is there a clinical trial for Breast Cancer recruiting anywhere in the world?

Yes. 1042 clinical trials for Breast Cancer carry a registry status of Recruiting. That figure counts only trials whose registry status is "Recruiting" and whose registry record agrees they are for this condition. Trials listed as not yet recruiting or enrolling by invitation are excluded, so this understates how many may open to new participants soon.

Is treatment for Breast Cancer subsidised on the PBS?

Yes. 24 medicines are listed on the Pharmaceutical Benefits Scheme against Breast Cancer, across 35 separate listings. A PBS listing means the Australian Government subsidises that medicine for the indications written into the listing, which is narrower than the condition as a whole: a medicine can be listed for one use and not another. The listing itself does not say whether a particular person can be prescribed it.

Is there a medicine for Breast Cancer registered for supply in Australia?

Yes. At least one medicine listed on the PBS against Breast Cancer is a registered product, and a product cannot be listed that way unless its active ingredients are already included in the Australian Register of Therapeutic Goods. That is a statement about the active ingredients being included in the Register, not about any brand, and not a statement that any government body endorses or recommends a treatment. Inclusion in the Register also says nothing about whether a particular medicine is suitable for a particular person.

Is a medicine used for Breast Cancer currently in short supply?

The Therapeutic Goods Administration currently reports a shortage of 1 of the 24 PBS-subsidised medicines listed for Breast Cancer: Vinorelbine. The TGA also expects a shortage of 1 of the 24, which is a supplier's forecast of a shortage that has not started rather than one happening now: Medroxyprogesterone. The TGA also has a discontinuation on record for 2 of the 24. A discontinuation applies to one registered product — a single brand, strength and dose form — so other brands or strengths of the same medicine may be unaffected: Goserelin, Trastuzumab. A shortage does not usually mean a medicine is unavailable everywhere; it often affects particular brands, strengths or pack sizes and not others. This is national information — neither the TGA nor Voxsanity publishes stock levels for individual pharmacies or states. If one of these is a medicine you take, a pharmacist can tell you what is available and discuss alternatives with your prescriber; do not stop or change a medicine without speaking to your doctor or pharmacist. These are matched counts, not a survey of Australian supply, and they understate rather than overstate: a medicine in shortage that the PBS does not subsidise for Breast Cancer, or that the TGA lists under an ingredient name we cannot match, does not appear here. The TGA publishes no reason for a shortage, so none is given.

Has a new medicine for Breast Cancer been added to the PBS in the last 12 months?

Yes. capivasertib reached the PBS for the first time in the 12 months to 18 August 2026. "New" here means the medicine reached the PBS Schedule for the first time inside the 12-month window, which is the point it became subsidised in Australia. It does not mean newly invented, and this is a subsidy event rather than a regulatory approval — a medicine can be available in Australia for years before it is subsidised, and this figure would not count that.

Advocacy and support in Australia

Organisations that can offer information, support, or connection for Breast Cancer. Where more than one is listed, they serve different needs or regions, so choose whichever fits your situation.

Breast Cancer Network Australia (BCNA) offers patient support and a member network. The National Breast Cancer Foundation (NBCF) focuses on funding research. Both are national bodies serving different needs.
