Abstract
Objective
To evaluate the association between induced abortion (IA) and breast cancer risk among Chinese females.
Methods
We searched three English databases (PubMed, ScienceDirect, and Wiley) and three Chinese databases (CNKI, WanFang, and VIP) for studies up to December 2012, supplemented by manual searches. Two reviewers independently conducted the literature searching, study selection, and data extraction and quality assessment of included studies. Random effects models were used to estimate the summary odds ratios (ORs) and the 95 % confidence intervals (CIs).
Results
A total of 36 articles (two cohort studies and 34 case&#8211;control studies) covering 14 provinces in China were included in this review. Compared to people without any history of IA, an increased risk of breast cancer was observed among females who had at least one IA (OR = 1.44, 95 % CI 1.29&#8211;1.59, I 2 = 82.6 %, p < 0.001, n = 34). No significant publication bias was found among the included studies (Egger test, p = 0.176). The risk increased to 1.76 (95 % CI 1.39&#8211;2.22) and 1.89 (95 % CI 1.40&#8211;2.55) for people who had at least two IAs and at least three IAs, respectively. Subgroup analyses showed similar results to the primary results. Meta-regression analysis of the included studies found that the association between IA and breast cancer risk attenuated with increasing percent of IA in the control group (&#946; = &#8722;0.022, p < 0.001).
Conclusion
IA is significantly associated with an increased risk of breast cancer among Chinese females, and the risk of breast cancer increases as the number of IA increases. If IA were to be confirmed as a risk factor for breast cancer, high rates of IA in China may contribute to increasing breast cancer rates.

China ought to have the world's largest testing ground for anything correlated with abortion.

As I can't access the actual study (needs $), I had to rely on the abstract. A lot of it is in statistic-ese, and since it's been some time since I took all two of my statistics classes, I may need some deciphering. I recognize that they're using z-scores, and that's about it.

Given their extreme pollution issues, I don't see why you'd want to use anything correlated to cancer in China.

Justice will be served, one way or another.

Kill a child, get breast cancer, you get what you deserve.

Did you know that carrying a child to term and giving birth also increases the risk for breast cancer?

By the way, yet another disgusting post out of you.

It's behind a paywall so I can't see what analyses were input into their meta-analysis, but enormous studies have been done in the past involving more than a million subjects in some cases and have found no link between abortion and breast cancer.

It's possible that this study changes the medical landscape on this, depending on its content, but I wouldn't hold my breath.

 

[Texashiker]

By the way, yet another disgusting post out of you.

Disgusting post because I object to the slaughter of innocent children?

In the womb - open season, kill as many as you want.

Out of the womb - oh the horror of anyone harming a child.

That mindset makes me sick.

I'd wager it's because you wished cancer on women who have abortions.

 

[OverVolt]

Could be a socioeconomic issue. The same women having abortions and can't afford to bribe for more children are probably the same ones living downstream from the factory pollution.

Looking over wikipedia and there appears to be a wide gamut of opinion.

I read your post, and decided I will keep my opinion to myself.

The slaughter of sperm! The slaughter of eggs monthly! The slaughter of fertilized cells! Outrage!!!

The fact that this hasn't been observed elsewhere, I would be more inclined to think it's sampling issues.

I've yet to hear anyone put forth a theory on the mechanics of abortion=> breast cancer. Other than loonies that are trying to justify views based on jesus loving babies or something.

Na, that is over simplification.

We are talking about a beating heart.

 

[fskimospy]

Not among medical experts and authoritative research bodies.

Just by Wiki's count the American Medical Association, American College of Obstetricians and Gynecologists, World Health Organization, the United States National Cancer Institute and the American Cancer Society have all evaluated the link and dismissed it.

Anything is possible, but that's an awful lot of research firepower that says there is no measurable link.

Kill a child, get breast cancer, you get what you deserve.

OK -- so women who have abortions deserve breast cancer, eh?

Yeah, this is a disgusting thing to say. You really need help, seriously.

To kill children is ok, eh?

Yeah, this is a disgusting thing to say. You really need help, seriously.

Yea, that is disgusting to say, you need help.

Should we feel sorry for the drug addict who caught hiv?

Should we feel sorry for the drunk driver who hits a tree?

 

[serpretetsky]

I want to confirm what I'm reading. This is simply a coorrelation right? They're not saying one necessarily can increase the chance of the other right?

 

[Atreus21]

To kill children is ok, eh?

No, it's not.

Neither is wishing death and misery on people who have abortions. Ultimate judgment is for God.

Should we feel sorry for the drug addict who caught hiv?

Yes.

Should we feel sorry for the drunk driver who hits a tree?

No.

 

[fskimospy]

Most research deals with correlations. You rarely see studies that say X caused Y, it is usually that one independent variable (abortion) is associated with an increase of the dependent variable (cancer). If you develop a significant body of research that all shows this correlation and you feel like you have adequately controlled for other variables, a reasonable conclusion would be that abortion causes breast cancer.

The only thing is that in this case the most credible evidence generally points the other way, that there is no link.

From what the abstract sez, the more abortions you have, the higher your risk for breast cancer.

You wish cancer on people, get some help. If you're a Christian you need to really step back and think if your wish for physical harm to other human beings is really something Jesus would teach.

 

[serpretetsky]

Everything I read in the abstract goes to great lengths to not imply one leads to the other. They use the term "association" repeatedly. Which leads me to believe there is a statistical coorelation, but having one is not necessarily cause for having the other.

For example (warning, this example may not be true!): Women that have abortions very often may also be statistically more likeley to ingest some sort of carcogen. The carcogen is the cause of the increased cancer. Simply getting more abortions does not increase cancer.

 

[Retro Rob]

To kill children is ok, eh?

No, but who are you to say that they deserve breast cancer?

Yea, that is disgusting to say, you need help.

LOL -- how is what I said disgusting? You DO need help if you're wishing cancer on people who do things you don't agree with.

Should we feel sorry for the drug addict who caught hiv?

If they deliberately ignored the consequences of using drugs, then no, I don't.

Should we feel sorry for the drunk driver who hits a tree?

No.

Should we feel sorry for the drug addict who caught hiv?

Shouldn't we?

Or are people only deserving of sympathy/pity/empathy if they've lived their life exactly the way you think they should?

Why don't you simply accept that the issue of abortion is quite a controversial one, and while you have your own opinion, listen and accept that others have opinions that differ from yours, instead of being a douchebag who thinks that it's OK to disparage others for their opinions, believes that yours is the only one that counts and wish death on other people?

 

[Texashiker]

You DO need help if you're wishing cancer on people who do things you don't agree with.

I never said I wished cancer on anyone.

You are jumping to conclusions.

Or are people only deserving of sympathy/pity/empathy if they've lived their life exactly the way you think they should?

You have your opinion and I have mine.
