Population screening…
Set criteria by World Health Organisation with a principle that ‘programs do more good than harm’ at a reasonable cost.
Geneva Switzerland
World Health Organisation Principles
• Aim to increase detection and reduce the impact of disease by testing a healthy population
• There must be a good chance that subsequent treatment can increase survival from the disease
• Australia uses modified WHO principles to guide screening programs
• Acceptable screening test repeated at intervals
Population based Australian cancer screening programs www.cancerscreening.gov.au
Evidence for a population screening program for breast cancer
• Studies and randomised controlled trials over 20 years in 4 countries
• First mammography programs 1987 - Iceland and Sweden
• Now standard in many western countries - U.S.A, Canada, U.K., Israel, France, Germany and Switzerland.
BreastScreen Australia – a population screening program for breast cancer
• BreastScreen Australia established 1991
• Joint funding state/territory and Commonwealth
• State/territory implementation, local services manage
• National Accreditation Standards
BreastScreen Australia
GoalTo reduce breastcancer mortalityby 30% throughearly detection
AimTo screen 70% of women in the 50 to 74 age group
Why do we do this?

BreastScreen Victoria – The facts
• Free breast cancer screening program
• Asymptomatic women aged between 50-74
• GP referral not required
• Female radiographers
* In May 2013 the Commonwealth Government announced an extension to the target age range to 50-74. This
will be a staggered roll-out over the next 3 years
Recommendations for breast screening
• Communication strategies target 50-74 year olds
• All women over 40 are eligible
• Recommended every 2 years
• Complements Breast Awareness
BreastScreen Victoria program
Why women aged 50 to 74?
• Evidence shows breast screening reduces the most deaths in this age group
• Mammograms are the most effective screening method for finding early breast cancer in this age group
• Women in 40s and over are 74 still at risk

BSV Results- 11/12 financial year
• 204,279 women screened
• 83% women were aged between 50-69 years
• 84% women returning for 2nd + screen
• 996 invasive cancers and 308 DCIS diagnosed
• 608 invasive cancers were 15mm or less
Benefits of BreastScreen
• Regular screening prevents deaths from breast cancer
• Breast screens can detect majority of cancers early – even
before they can be felt or noticed.
• If breast cancer is found early, it is more likely to be small,
and successfully treated
• The earlier breast cancer is found, the better your chance
of surviving it
Limitations of BreastScreen
• Anxiety
• Over – treatment:
• Some women may be diagnosed with breast cancer that would not develop into a life-threatening cancer, therefore, some women may receive treatment that might not have been necessary.
• Exposure to radiation • Modern mammography machines use the smallest amount of radiation
possible while still getting a high quality X-ray picture. The radiation from screening (which involves two X-rays of each breast) is about the same as 18 weeks of exposure to natural radiation in the environment.
