Breast Cancer & Women


One in eight women in Australia will develop breast cancer before the age of 85 years.1 Women-together_w.jpg

Amongst other factors, some of the risk factors for breast cancer:

  • Being a woman

  • Age - the risk increases as you get older. Information from Cancer Australia6 tells us that about 75% of breast cancer cases in women occur after 50 years of age. Of the 15,600 women expected to be diagnosed with breast cancer in 2015, an estimated 795 women will be diagnosed between the ages of 20 and 39. This accounts for 5% of all breast cancers diagnosed.

  • Family history - women with a family history of breast cancer are 1.5 – 3.9 times more likely to develop breast cancer than are women without a family history, depending on the number and degree of relatedness of the family members affected.6
  • Medical history

  • Drinking alcohol

  • Being overweight

  • A number of hormonal factors

  • Child-bearing history 2
