Risk factors for females include the following:

  • Age older than 40 years
  • Family history of a first-degree relative with breast cancer
  • Menarche before age 12 years
  • Menopause after age 55 years
  • Nulliparity
  • First pregnancy after age 30 years
  • Therapeutic radiation over chest before age 30 years
  • Prediagnosis hormone replacement therapy remains controversial [32]
  • A history of smoking tobacco products for more than 15 years [33]
  • BRCA1 and BRCA2 mutations (responsible for approximately 5% of all breast cancers; inherited in an autosomal dominant fashion; women with mutations in either of these genes have a lifetime risk of breast cancer of 60%-85% and a lifetime risk of ovarian cancer of 15%-40%) [34]
  • Paget disease of the breast [35]
