It’s the most commonly diagnosed cancer in Australian women, and with more than 20,000 people diagnosed with the disease last year alone, chances are you know someone with breast cancer. What’s a breast cancer check and who does it? A mammogram (an x-ray of your breasts completed by a radiographer) is the recommended screening tool for detecting breast cancer early. Although your chances of developing cancer are low when you’re young, keep in mind that 7% of women diagnosed with breast cancer worldwide are under 40. If you have a family history of breast cancer, your doctor may begin conducting breast examinations in your teenage years.
