Find your recommended mammogram screening pathway based on Australia's BreastScreen program — including the actively-invited 50–74 age group, self-referral eligibility, and when a personalised schedule from your doctor applies instead.
If you're aged 50 to 74, BreastScreen Australia actively invites and recommends a free mammogram every 2 years — this is the core target group for population screening. If you're 40–49 or 75 and over, you're still eligible for a free mammogram but you'll need to self-refer rather than wait for an invitation. Under 40, routine population screening isn't recommended, and mammograms at that age are usually only done for specific clinical reasons on a doctor's advice. Anyone at higher-than-average risk should follow a personalised schedule set by their doctor or specialist instead of the standard interval.

This calculator applies the standard population pathway used by BreastScreen Australia, the national mammogram screening program. It considers your age, whether you've indicated a higher-than-average risk factor, whether you'd like a supplementary note about earlier screening discussions as an Aboriginal or Torres Strait Islander woman, and, optionally, the date of your last mammogram, to estimate your general pathway and next due date.
| Age Range | Standard Pathway |
|---|---|
| Under 40 | Not recommended for routine screening — mammograms only for specific clinical reasons, on a doctor's advice |
| 40–49 | Eligible for a free mammogram — self-refer (not automatically invited) |
| 50–74 | Actively invited for a free mammogram every 2 years |
| 75+ | Still eligible for a free mammogram — self-refer (not automatically invited) |
| Higher-than-average risk (any age) | Personalised schedule set by your doctor or specialist |
A mammogram is a low-dose X-ray of breast tissue, usually taken from two angles for each breast. A specially trained mammographer positions the breast and briefly compresses it between two plates so the image is clear — the compression itself only lasts a few seconds per view, and the whole appointment is typically quite short. Some people find the compression mildly uncomfortable for a moment, but it shouldn't be painful, and you can always let the mammographer know if you need a pause.
BreastScreen Australia is the national program that provides free mammograms to eligible people. Its approach is split by age: people aged 50 to 74 are actively invited, meaning the program proactively sends reminders roughly every two years, because this is where population-wide screening delivers the clearest overall benefit. People aged 40 to 49 and those 75 and over are still eligible for exactly the same free service, but they aren't automatically chased up — they need to self-refer, which simply means picking up the phone or booking online themselves rather than waiting for a letter. Under 40, the program doesn't offer routine population screening at all, since mammograms are less useful as a general screening tool at younger ages and any imaging needed is instead directed by a doctor for a specific clinical reason.
| Age / Situation | Standard Pathway | Notes |
|---|---|---|
| Under 40 | No routine screening | Mammograms only for specific clinical reasons, on your doctor's advice |
| 40–49 | Self-refer for a free mammogram | Eligible but not automatically invited; benefit is smaller than for 50–74 |
| 50–74 | Automatically invited, free, every 2 years | Core target group for population screening |
| 75+ | Self-refer for a free mammogram | Still eligible; automatic invitations stop after age 74 |
| Any age, higher-than-average risk | Personalised schedule from your doctor or specialist | Standard 2-yearly interval does not apply |
| Aboriginal/Torres Strait Islander, under 50 | Consider starting the conversation from age 40 | Gentle guidance — discuss timing with your GP or Aboriginal Health Worker |
Aboriginal and Torres Strait Islander women may wish to start considering mammogram screening discussions from around age 40, a little earlier than the standard 40–49 self-referral guidance implies for the general population, reflecting documented health equity considerations in breast cancer outcomes. This is offered as gentle, general guidance rather than a strict rule — the most useful next step is simply a conversation with your GP or an Aboriginal Health Worker, who can talk through timing and options that suit you personally.
Why are ages 50 to 74 the actively invited group for mammograms?
BreastScreen Australia focuses its automatic invitations on the 50–74 age band because this is where population screening delivers the clearest overall benefit. If you're in this age range, you can expect an invitation roughly every two years for a free mammogram — you don't need a doctor's referral to take part.
What does "self-refer" actually mean?
Self-referring simply means booking your own mammogram appointment with BreastScreen Australia rather than waiting for an invitation letter. It's available to eligible people aged 40 and above who aren't in the actively-invited 50–74 group — you contact the service yourself, at a time that suits you, instead of being sent a reminder.
Why isn't routine mammogram screening recommended under 40?
Below age 40, population-wide mammogram screening isn't recommended because breast cancer is far less common at this age and mammograms are less useful as a general screening tool in younger women. If a mammogram is needed under 40, it's usually because a doctor has identified a specific clinical reason to investigate — not as part of routine screening.
What should I do if I'm at higher-than-average risk of breast cancer?
If you have a strong family history, a known BRCA1 or BRCA2 gene mutation, a history of chest radiotherapy, or you've had breast cancer yourself, your screening needs may differ from the general population. Speak with your doctor or a specialist about a personalised plan — this can mean starting earlier and/or screening more often than the standard two-yearly interval, and this calculator deliberately won't try to set that schedule for you.
What actually happens during a mammogram?
A mammogram is a low-dose X-ray of breast tissue, usually taken from two angles for each breast. A trained mammographer positions and briefly compresses the breast between two plates to get a clear image — the compression only lasts a few seconds per view, and the whole appointment is typically quite short.
Is a BreastScreen Australia mammogram really free?
Yes. Mammograms through BreastScreen Australia are provided at no cost to eligible people, whether you're automatically invited (ages 50–74) or you self-refer (ages 40–49 and 75+). There's no separate fee needed because the service itself is free at the point of care.
How do I book a mammogram appointment?
If you're aged 50 to 74, you'll typically receive an invitation with instructions for booking. If you're outside that range but still eligible (40–49 or 75+), you can contact your local BreastScreen Australia service directly to arrange an appointment — no GP referral is required either way.
What happens if my mammogram result comes back abnormal?
If your result shows something that needs a closer look, BreastScreen Australia will contact you to arrange further tests, such as additional imaging or a biopsy. An abnormal result doesn't automatically mean cancer — many follow-up assessments turn out to be non-cancerous — but it's important to attend any follow-up appointments promptly and discuss the result with your doctor. This calculator only estimates screening timing; it cannot interpret results.
I'm 75 or older — can I still get a free mammogram?
Yes. BreastScreen Australia doesn't send automatic invitations once you're past 74, but you remain eligible for a free mammogram for as long as you want to keep screening. You simply self-refer and book directly, and it's worth chatting with your doctor about whether continuing suits your individual circumstances.
Should Aboriginal and Torres Strait Islander women start screening earlier?
Aboriginal and Torres Strait Islander women may wish to start considering screening discussions from around age 40, reflecting documented health equity considerations in breast cancer outcomes. This is general, gentle guidance rather than a fixed rule — the best next step is a conversation with your GP or an Aboriginal Health Worker about what timing suits you.
