About one percent of breast<unk>  develops in<unk> s. It is estimated that about 2,140 new cases are diagnosed annually in the United States (US) and about 300 in the United Kingdom (UK). The number of annual deaths in the US is about 500. In a study from India, eight out of 1,200 (0.7%)<unk><unk>  diagnoses in a pathology review represented breast<unk> . Incidence of<unk>  has been increasing which raises the probability of other family members developing the disease. The relative risk of breast<unk>  for a female with an affected brother is approximately 30% higher than for a female with an affected sister. The tumor can occur over a wide age range, but typically appears in<unk> s in their sixties and seventies. Known risk factors include radiation exposure, exposure to female hormones (estrogen), and genetic factors. High estrogen exposure may occur by medications, obesity, or liver disease, and genetic links include a high prevalence of female breast<unk>  in close relatives. Alcohol use disorder has been linked to<unk> . The highest risk for<unk>  is carried by<unk> s with Klinefelter syndrome.<unk>  BRCA mutation carriers are thought to be at higher risk for breast<unk>  as well, with roughly 10% of<unk>  cases carrying BRCA2 mutations, and BRCA1 mutation being in the minority.
