October is Breast Cancer Awareness Month, which means pink ribbons, fundraising walks, and a fair few reminders to “get checked.” But between all the awareness-raising, the actual practical questions tend to get skipped — what does a mammogram involve, does it hurt, who’s even eligible for one? If you’ve been putting off booking one because you’re not quite sure what to expect, you’re not alone. A lot of the hesitation around breast screening comes down to the unknown rather than the process itself, and this is genuinely the month to sort that out rather than let it slide another year.

Breast cancer is the most commonly diagnosed cancer among Australian women, and the numbers are worth sitting with for a second: 1 in 7 women will be diagnosed with it in their lifetime. The flip side of that statistic is a more hopeful one — five-year survival rates have climbed from 75% to 94% since the late 1980s, largely because screening catches so much of it early. So let’s clear up what screening actually looks like, in plain terms.

Who’s actually eligible

BreastScreen Australia offers free mammograms to any woman aged 40 and over, no GP referral needed. Women aged 50 to 74 get an invitation in the mail every two years, but that’s a nudge, not a requirement — you can access the free service from 40 and keep going well past 74 if you want to.

If you’ve got a family history of breast cancer — particularly a first-degree relative diagnosed before 50, or diagnosed in both breasts — talk to your GP, since you may be recommended for screening earlier or more frequently than the standard two-year cycle.

What a mammogram actually is

A mammogram is a low-dose x-ray of breast tissue, designed to pick up changes well before they can be felt. That’s the whole point of screening — catching something small and treatable long before it becomes a lump you’d notice yourself. Around a quarter of breast cancer diagnoses happen in women under 50, so this isn’t a “wait until you’re older” issue either.

What to expect on the day

• It’s quick. The appointment itself takes about 20 minutes, and the actual imaging is a matter of minutes.
• It can be uncomfortable, not agonising. Each breast is compressed briefly between two plates to get a clear image. Most people describe it as a firm squeeze rather than genuinely painful, and it’s over fast.
• Timing matters. If you still get a period, booking your mammogram for the week after it finishes can make things more comfortable, since breast tissue is less tender then.
• Wear separates. You’ll need to undress from the waist up, so a shirt and skirt or trousers beats a dress.
• Results take a couple of weeks. They’re sent by mail, and the vast majority come back clear. Being called back for more images isn’t bad news — it often just means the radiologist wants a clearer look.

Self-checks still matter

Screening mammograms are for people without symptoms — they’re a background safety net, not a substitute for knowing your own body. Getting familiar with how your breasts normally look and feel makes it much easier to notice if something changes. If you ever do notice a lump, dimpling, discharge, or anything that feels different, see your GP without delay rather than waiting for your next scheduled screen.

The bottom line

Breast screening is free, it’s fast, and it’s one of the few genuinely simple things you can do that measurably improves your odds if something is there. If it’s been longer than two years, or you’ve never had one at all, October’s as good a reason as any to book it in. You can check your eligibility and book directly through BreastScreen Australia, or start with a conversation with your GP.

Gr8 Health is committed to raising awareness of breast cancer, not just for Breast Cancer Awareness Month, but year-round. This cause is close to our hearts — our founder, Sam, lost his sister to breast cancer, and it’s a big part of why early detection and open conversations about breast health matter so much to us.
