Reproductive Factors

Reproductive factors are known to influence hormone-related cancers like those of the breast and ovary. Some can be classified as lifestyle factors (such as parity), while others are classified as host factors (age at menarche).  DCEG researchers investigate the role of parity (the number of live-born children a woman has delivered), infertility, age at menarche and menopause and other factors in relation to cancer risk.
