It cannot be said that all women who have breast cancer have had abortions.  Similarly, not all women who have had abortions will get breast cancer.  Nevertheless, abortion is the most preventable risk factor for breast cancer.





Women have the right to know that two breast cancer risks are associated with abortion - a recognized risk and a debated risk.


All experts agree that the longer a woman waits to have her first full term pregnancy, the greater her breast cancer risk is. Delaying the birth of a first child significantly increases risk because the childless woman has immature, cancer-vulnerable breast tissue - Type 1 and 2 lobules where 95% of all breast cancers are known to develop. Her breast tissue does not mature into cancer-resistant tissue until the last months of a full term pregnancy. By the end of a 40-week pregnancy, 85% of her breast lobules are mature, cancer-resistant lobules known as Type 4 lobules.

A delayed first full term pregnancy increases her risk because it extends the length of time during which her breasts remain susceptible to carcinogens. Scientists define an early first full term pregnancy as one that takes place before age 24.

Although delaying the birth of a first child is a known cancer risk, few experts have the intellectual honesty or the political courage to admit that abortion contributes to the breast cancer epidemic by causing a countless number of women to delay their first full term pregnancies every year.


Experts debate whether an abortion further increases risk by leaving the woman with more cancer-vulnerable breast tissue than she had before she became pregnant. This effect is known as the "independent link."

The breasts grow considerably during pregnancy while under the influence of high levels of the hormone estrogen, a known carcinogen. Estrogen causes the woman's normal and cancer-vulnerable breast lobules to multiply. If she has an abortion, she's left with more places for cancers to start in her breasts. If she has a baby, then other pregnancy hormones mature her breast lobules into cancer-resistant lobules during the last months of pregnancy. She's left with more cancer-resistant tisue than she had before she became pregnant.

Seventy-two epidemiological studies have been conducted since 1957; and 80% of these studies have shown that abortion increases the risk of breast cancer independently of the effect of delaying the birth of a first child. These epidemiological studies establish a correlation between abortion and increased breast cancer risk. Most of the recent epidemiological studies focus exclusively on the effect of the independent link, not the known risk of delaying the birth of a first child.

Niagara Region Right to Life contracted LifeSiteNews to host a series of on line, half hour videos of a television program on life issues produced by the Life Issues Institute in Cincinnati, Ohio. The series, with host Brad Mattes, has been praised for its high quality, compelling and accurate productions on these crucial matters.

The series begins with "The Surprising Link", a convincing and moving investigation of the link between abortion and breast cancer.

The First video presents moving, compelling evidence of the abortion/breast cancer link. To view the video, visit:
