Teenagers are most vulnerable and negatively impacted by abortion
and hormonal contraception.
At a time when
their breasts are already growing, induced abortion alters their
physiology in a way that results in a much higher risk of subsequent
abortion, a woman increases her risk of breast cancer in four
she creates in her breasts more places for cancers to
start, which is the “independent effect”;
she loses the
protective effect that a full-term pregnancy would have afforded
she increases the risk of premature delivery of future
thus losing the benefit to breast cells that a full-term
pregnancy gives; and
she lengthens her susceptibility window.
Following abortion, many teen women take hormonal contraceptives
that in most circumstances can elevate the risk of breast cancer
even more. Contraceptives containing estrogen-progestin
drugs increase breast-cancer risks by causing breast cells to
proliferate increasing the chance of mutations leading to cancer
cells, and by acting as direct carcinogens.
