exp:

  • Family history of even 2nd degree relatives is associated with increased risk, although much less than that with 1Stdegree relatives.

  • Administration of estrogens alone is not associated with increased risk of breast cancer

Concamitant administration of progesterone and estrogen increase the risk of breast cancer. [Harrison 17/e p.563; Sabiston 18/e p864]
