Does that also apply to miscarriages?
Apparently not. From righttolife.org:
"Is abortion a risk factor for breast cancer?
When a woman becomes pregnant her body begins to go through biological changes in order to prepare for childbirth. Increased levels of estrogen during pregnancy cause a woman’s breasts to enlarge with cells that will eventually allow for milk production. By the time of a full-term birth these cells have differentiated into milk producing tissue and have stopped multiplying. These cells are resistant to cancer because they have been differentiated into a specific type of cell and the cell multiplication process has been stopped.
If a woman has an abortion before her 3rd trimester of pregnancy, her breasts are left with more undifferentiated cells that are more vulnerable to cancer than if she had never been pregnant.
What about miscarriages?
Researchers have found that most miscarriages don’t raise the risk of breast cancer because these pregnancies don’t produce enough estrogen, which is the driving factor behind the proliferation of undifferentiated, cancer-vulnerable cells.
What do the scientific studies show?
Fifty-eight out of 74 worldwide studies dating back to 1957 show that abortion increases a woman’s risk of getting breast cancer later in life. In studies done on women from the United States, 19 out of 24, show an increased risk of breast cancer associated with abortion."
I guess the next "non-argument" will be oh, that's hardly an impartial site...?
It might, but misscarriage is not a choice, it is a natural phenomona. Therefore, it is a non-sequitor straw man to bring into the discussion.
