Protective Effect of First Full Term Pregnancy on Breast Cancer (review 2/05)

ACOG, along with the NCI,  agrees that a first full term pregnancy [FFTP] confers a “protective effect” against future development of breast cancer: Yet, [ACOG and NCI] continue to deny the impact of the sudden termination of that pregnancy:  “Long term risks, sometimes attributed to surgical abortion include potential effects on reproductive function, cancer incidence, and psychological sequelae. However, the medical literature, when carefully evaluated, clearly demonstrates no significant negative impact on any of these factors with surgical abortion.”  They are demonstrably wrong in all three categories. Consider the information below: Protection Against Future Breast Cancer First Pregnancy Delivered vs. First Pregnancy Aborted A Gail Model Risk Analysis The protective effect of an early first full term pregnancy [FFTP] against future development of breast cancer has been undisputed for 35 years. The landmark study establishing this protective effect [MacMahon, et al, (1970) Bulll WHO 43:209-221] is widely accepted in  the medical world.  MacMahon, and group reanalyzed their 1970 data [Trichopolous D, Hsieh C, MacMahon B, Lin T, et al,, Age at any Birth and Breast Cancer Risk, International J Cancer, 1983:31:70l-704], finding that each one year delay in the first full term pregnancy increased relative breast cancer risk by 3.5% (compounded).  Obviously, aborting a first pregnancy eliminates the protective effect against breast cancer. In an attempt to calculate the risk in numbers that both patient and physician can more readily relate to, Thorp applied the Gail model risk analysis to typical real-life situations (Thorp et al., Long Term Physical and Psychological Health Consequences of Induced Abortion: Review of the Evidence; Obstetrical and Gynecological Survey, Vol 58, #1, Jan 2003, pp 75,76).  The following...
