Summary: Higher Exposure to
Estrogen, Higher Risk of Breast Cancer
The Breast Cancer Prevention Institute claims that the more estrogen
a women is exposed to in her lifetime, the higher her risk for
breast cancer. Abortion in women under 18 and over 30 years old
carries the greatest risk of getting breast cancer.
Fact sheet from the Breast Cancer Prevention
Institute claims that the physiology of the breast provides the
strongest evidence of the causal link between abortion and breast
cancer. This is based on two principles: the more estrogen a woman
is exposed to in her lifetime, the higher her risk for breast cancer.
This is due to the fact that estrogen can cause cancer by either
damaging DNA inside the cells or by causing cells to divide without
control. If a woman starts
her menstrual cycle early and continues to menstruate into her late
50ís, she is at higher risk for breast cancer, as she has been
exposed to monthly estrogen elevations for a long period of time.
The second principle indicates that the earlier a woman's breast
matures from prepubescent to reproductive/lactative, the lower her
risk of breast cancer. Women who undergo full-term pregnancies have a lower risk of breast
cancer and women who remain childless have a higher risk of breast
cancer. Abortion in women under 18 and over 30 years old carries the
greatest risk because these women have the highest percentage of
immature lobules in their breasts (this is where the cancers usually arise).1
