In Australia, BreastScreen actively invites women aged 50–74 to a free mammogram every two years — this is the main target group. Women aged 40–49 and 75+ are also eligible for free mammograms but aren't sent invitations. If you have symptoms or a strong family history, talk to your doctor, as you may need a different approach regardless of age.
Key takeaways
- BreastScreen actively invites women aged 50–74 (the main target group).
- Women 40–49 and 75+ can attend free but aren't sent invitations.
- Screening every two years is the standard interval in Australia.
- Symptoms or strong family history warrant a doctor's advice at any age.
“What age should I start?” is one of the most common questions about mammograms. In Australia, the answer is built around the BreastScreen program — and it differs from some overseas guidance, so it’s worth knowing the local rules.
How the ages work in Australia
- Ages 50–74 — BreastScreen actively invites women in this group to a free mammogram every two years. This is the main target group, where screening is most beneficial.[1]
- Ages 40–49 — eligible to attend free, but not sent invitations. Some women in this group choose to screen; it’s worth discussing with your doctor.[1]
- Ages 75 and over — also eligible for free mammograms, but not actively invited.[1]
You don’t need a referral to attend BreastScreen. (Some overseas programs, such as in the US, suggest starting annual screening at 40 — Australia’s program is 2-yearly and targets 50–74, so follow the local guidance and your doctor’s advice.)
Symptoms or family history change the picture
These ages are for routine screening of people without symptoms. At any age, if you notice a breast change — a lump, or skin or nipple change — see your doctor rather than waiting.[2] And if you have a strong family history of breast cancer, talk to your doctor, as you may need to start earlier or have additional tests such as MRI.
Frequently asked questions
When does BreastScreen start inviting you?
From age 50 — BreastScreen actively invites women aged 50–74 every two years. You can attend free from 40, but won’t be sent an invitation before 50.[1]
Should I get a mammogram in my 40s?
You can attend BreastScreen free from age 40. Whether to start then is worth discussing with your doctor, particularly if you have a family history.[2]
I’m over 75 — can I still be screened?
Yes — women 75 and over remain eligible for free mammograms, though they aren’t sent invitations. Discuss the benefits with your doctor for your situation.[1]
