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.
Examples of studies used in these investigations include:Columbia, Missouri Serum Bank Follow-up Study
Follow-up Study of Women Evaluated and Treated for Infertility
Follow-Up Study of Women in the Fracture Intervention Trial (FIT)
Methodologic Study of Tissue Hormones
NIH-AARP Diet and Health Study
Prostate, Lung, Colon, and Ovary Prospective Study
Testicular Cancer among Military Servicemen: the STEED Study
