Which mammogram path do you need?

No symptoms? Screening
BreastScreenRoutine screening with no symptoms is handled by the free government program — book directly with BreastScreen Victoria via their official website. No referral needed.

Symptoms? GP first
Don't waitA lump, pain, discharge, or skin change needs a diagnostic work-up, not a screening slot. See your GP promptly for a referral.

Referral works anywhere
Your choiceYour referral isn't locked to one provider. Compare mammography clinics on Radly — bulk billing, prices, and how soon you can get in — and request a time online.

Report to your GP
1–3 daysFor diagnostic mammograms, a radiologist reports to your referring GP, usually within a few days — often with a breast ultrasound done in the same visit.
What is BreastScreen Victoria?
BreastScreen Victoria is the Victorian part of BreastScreen Australia, the government-run program that provides free screening mammograms to eligible women. It operates separately from private radiology clinics - you book directly with the program, and no GP referral is needed for screening.
Radly is not affiliated with BreastScreen Victoria and doesn't take bookings for the program. For eligibility, locations, appointment details, and bookings, always go to the official BreastScreen Victoria website - it's the source of truth for how the program works.
What this guide can help with is the question many women get stuck on: whether screening is the right path for you, or whether you need a diagnostic mammogram at a radiology clinic instead.
Screening vs diagnostic mammogram: the key difference
Both use the same type of imaging, but they answer different questions:
• Screening mammogram - a routine check for women with no breast symptoms, looking for changes too small to feel. In Australia this is what the free BreastScreen program provides. • Diagnostic mammogram - a targeted examination when there's a specific concern: a lump, pain, nipple discharge, skin change, or something that needs a closer look. This is done at a radiology clinic with a GP referral, often together with a breast ultrasound, and with Medicare the out-of-pocket cost is commonly $0-$80.
The rule of thumb: no symptoms and just due for a check → screening via BreastScreen. Any symptom or specific concern → GP first, then a diagnostic mammogram. See our full mammogram guide for what the test itself is like.
Who is free screening for?
Eligibility for free screening is set by the BreastScreen program and is broadly age-based - women from their 40s upward can attend, with the program actively inviting its target age group every two years. Because the details (ages, intervals, and locations) are the program's to define and can change, check the current rules on the BreastScreen Victoria website rather than relying on any third-party summary, including this one.
One thing that doesn't change: screening is specifically for women without symptoms. If you've noticed any breast change, screening is not the right queue to wait in - see your GP promptly instead.
Women at higher risk (strong family history, known gene mutations like BRCA1/2) may need a different schedule or additional imaging - that's a conversation for your GP.
When do I need a diagnostic mammogram instead?
See your GP - and expect a referral for diagnostic imaging rather than screening - if you have:
• A new lump or thickening in the breast or armpit • Breast pain that persists • Nipple discharge or a newly inverted nipple • Skin changes - dimpling, redness, puckering • A finding from screening that needs further tests • A strong family history your GP wants investigated
A diagnostic work-up is more thorough than a screen: extra mammogram views, usually a breast ultrasound, and sometimes a biopsy. It's also faster to arrange when something needs answers - you're not waiting for a routine screening slot.
How do I book a diagnostic mammogram?
Once your GP writes a referral:
1. Your referral works at any radiology clinic that offers mammography - not just the one printed on the form 2. Compare mammography clinics near you on Radly - check bulk billing, prices, and how soon you can get in 3. Request a booking online with your referral - the clinic replies with its next available time
Before the appointment: skip deodorant, powder, and creams on the day (they can affect the images), wear a two-piece outfit, and bring any previous breast imaging so the radiologist can compare.
If you're after free routine screening with no symptoms, that path stays with BreastScreen Victoria directly.
