Breast cancer risk is not the same for every woman. While population-level screening programs are designed around average risk, a meaningful proportion of women have personal or family histories that place them at a level of risk that warrants a different screening approach — starting earlier, screening more frequently, or using more sensitive imaging modalities than standard mammography alone.

A formal breast cancer risk assessment with a breast specialist provides a clear, evidence-based picture of your individual risk level and translates that into practical, personalised screening advice. It is one of the most useful and empowering consultations a woman concerned about breast cancer risk can have.

What Does a Risk Assessment Involve?

At your consultation, your surgeon will take a comprehensive history covering the following areas.

Personal history — any previous breast conditions, biopsies, and their findings; prior breast imaging results; reproductive history including age at first period, pregnancies, breastfeeding, and menopausal status; and current and past use of hormonal medications including the oral contraceptive pill and hormone replacement therapy.

Family history — a detailed account of breast and ovarian cancer in your family, including which relatives were affected, their ages at diagnosis, whether bilateral disease was present, and whether any family members have undergone genetic testing. Family history on both the maternal and paternal sides is relevant.

Lifestyle and other risk factors — weight, alcohol consumption, physical activity, and smoking history are all documented as part of a complete risk profile.

Breast density — if you have had a recent mammogram, the reported breast density is an important component of risk assessment, as dense breast tissue is both associated with elevated risk and affects the sensitivity of mammographic screening.

This information is used alongside validated risk assessment tools — such as the Tyrer-Cuzick model — to estimate your lifetime and ten-year risk of developing breast cancer, and to classify your risk as average, moderately elevated, or high.

If you would like to assess your risk of breast cancer, we suggest using the online tool iPrevent.  It is important to know your mammographic breast density as stated on your last BreastScreen assessment or Mammogram report, as well as knowing your’s family’s history - family members' ages, and age of cancer onset.  The more detail you put in, the more accurate the risk estimate is.  Family members without cancer are just as important as those with cancer for the tool to be accurate.

Screening Recommendations by Risk Level

Average risk — women at average population risk are recommended to participate in two-yearly screening mammography through BreastScreen Australia from age 50 to 74. Women aged 40 to 49 and 75 and over are also eligible for free BreastScreen mammography on self-referral. Annual clinical breast examination and ongoing breast awareness are encouraged for all women regardless of risk.

Moderately elevated risk — women at moderately elevated risk based on family history or personal risk factors may be advised to commence mammographic screening earlier than the standard program (typically from age 40), to screen annually rather than two-yearly, and in some cases to add ultrasound as a supplementary tool. Referral to a familial cancer service for genetic counselling may be recommended.

High risk — women at high risk, including confirmed gene mutation carriers and those with a very strong family history or prior high-risk breast lesion, are recommended an intensive surveillance program incorporating annual breast MRI and mammography commencing from age 30 to 35, regular clinical examination, and coordinated specialist review. Risk-reducing interventions including chemoprevention and prophylactic surgery are also discussed where appropriate for this group.

Who Should Have a Formal Risk Assessment?

A formal specialist risk assessment is particularly worthwhile in the following situations. You have one or more first-degree relatives diagnosed with breast cancer, particularly at a young age. You have a family history that includes both breast and ovarian cancer, or bilateral breast cancer in a family member. A male relative has been diagnosed with breast cancer. You have been told you have dense breast tissue and want guidance on whether additional screening is appropriate. You have previously had a breast biopsy showing a high-risk lesion such as atypical ductal hyperplasia or lobular carcinoma in situ. You have had prior chest radiotherapy. You are of Ashkenazi Jewish ancestry. You simply want a specialist opinion on whether your current screening approach is appropriate for your circumstances.

A risk assessment is also useful for women who have been anxious about their breast cancer risk for years without ever having had a formal discussion with a specialist. For many patients, the assessment provides genuine reassurance that their risk is closer to average than they feared.

Frequency and Duration of Surveillance

High-risk surveillance is a long-term commitment. For confirmed gene mutation carriers, annual MRI and mammography is recommended from the age specified by current guidelines through to age 70 to 75, at which point the surveillance program is reviewed. The frequency and modalities used are adjusted as the patient ages, as breast density changes, and as new evidence or updated guidelines emerge.

For women who proceed with risk-reducing mastectomy, formal breast imaging surveillance of the chest wall is not routinely required after surgery, as the risk is substantially reduced. However, clinical review and ongoing surveillance of the residual risk continues under specialist oversight.

After Your Assessment

At the end of your consultation you will have a clearly documented risk estimate, a personalised screening and surveillance plan with specific recommendations for imaging type, frequency, and starting age, guidance on whether referral for genetic counselling is warranted, and practical advice on modifiable lifestyle risk factors where relevant.

We communicate the outcome of your assessment clearly in writing to both you and your referring GP, so that your screening plan is documented and can be followed consistently over time.

Booking an Appointment

A GP referral is required for a specialist risk assessment consultation. If you have concerns about your personal or family history of breast cancer and would like a formal assessment, please ask your GP for a referral to our practice.
