Summary: Induced Abortions and
Estrogen: A Likely Cause for Breast Cancer
According to Dr. Angela Lanfranchi, abortion causes breast cancer in
about 5% of women who have an abortion. This results in
approximately 10,000 cases a year of breast cancer that can be
attributed to abortion. After an induced abortion, the female is
exposed to very high levels of estrogen, which can act as a mitogen
and a carcinogen on breast tissue. This would
leave her with more places for cancers to start.
In an article written by Dr. Angela Lanfranchi in
a journal called Imago Hominis, the author talks about the ongoing
controversy regarding the link between breast cancer and abortion.
According to Lanfranchi, abortion causes breast cancer in about 5%
of women who have an abortion. This results in approximately 10,000
cases a year of breast cancer that can be attributed to abortion.
Studies have shown that the longer a pregnancy exists before an
abortion, the higher the risk of breast cancer. This is due to the
presence of estrogen in the breast. During normal pregnancy, breast
tissue contains microscopic units called lobules, which mature and
differentiate to become functional mammary tissue (type 3 lobules).
After an induced abortion, breast tissue does not achieve this
maturation and estrogen levels remain very high. Estrogen then
induces the proliferation of the more immature (type 1 and 2)
lobules, which are more sensitive to DNA damage and cancer
formation. A woman who is pregnant and gets an abortion loses the
protection against breast cancer that a full term pregnancy would
have given her because more cancer-resistant type 3 lobules would
not be formed and the higher numbers of the immature lobules would leave her breast with more places for
cancers to start. Abortions also increase the risk of having
premature deliveries of subsequent pregnancies which in themselves
increase the breast cancer risk.1
