BreastScreen Australia provides free two-yearly breast cancer screening to women through dedicated screening and assessment services. Women have a screening mammogram performed at a screening unit (which may be fixed, relocatable or mobile).
Women whose images are suspicious for breast cancer will be recalled for further investigation by a multidisciplinary team at an assessment centre. Further investigation may include clinical examination, mammography, ultrasound and biopsy procedures. Most women who are recalled for assessment are found not to have breast cancer.
BreastScreen Australia actively invites women aged 50-74 to have free two-yearly breast cancer screening. Women aged 40-49 and 75 or over are also eligible to attend. Women aged 50-74 are targeted because the risk of breast cancer has been found to increase with age, and screening mammography is known to be effective in reducing breast cancer deaths in this age group.
Screening mammography is less accurate in women under 40. Breast tissue in younger women is denser than in older women. As dense breast tissue and cancer both appear opaque on an x-ray, detecting cancer using mammogram in younger women is less likely to be accurate.
Given its reduced effectiveness in women under 40, the cost of mammogram in this age group (eg undergoing unnecessary procedures, discomfort during screening, exposure to low-dose radiation) is currently thought to outweigh the benefits.
