OBJECTIVE South Asia, a historically low-incidence region for breast cancer, has produced many recent studies examining reproductive factors. We compiled these studies to confirm the reality of the significant association reported in the first, 1996 review of induced abortion as a risk factor, independent of abortion's known effect in abrogating the protection afforded by full-term pregnancy. METHODS We searched the medical literature for English language studies on breast cancer incidence in…

Menstrual and Reproductive Factors and Risk of Breast Cancer in Iranian Female Population: A Systematic Review and Meta-Analysis
TLDR

Reproductive history and breast cancer risk in women: based on logistic regression and survival analysis
TLDR
This study investigated the association between reproductive history and breast cancer risk of American women and found that receiving oophorectomy (both ovaries removed) has a positive association with Breast cancer risk, while the age at first live birth has a reduced risk in for women under 60 years old.
Geospatiotemporal and causal inference study of cannabis and other drugs as risk factors for female breast cancer USA 2003–2017
TLDR
Data show that exposure to cannabis and the cannabinoids Δ9-tetrahydrocannabinol, CBD, CBG and alcoholism fulfil quantitative causal criteria for BCI across space and time and establish cannabinoids as an additional risk factor class for breast carcinogenesis.

Induced Abortion as an Independent Risk Factor for Breast Cancer: A Critical Review of Recent Studies Based on Prospective Data
TLDR
Ten recent studies based on prospective data collection do not invalidate the large body of previously published studies that established induced abortion as a risk factor for breast cancer and should be part of the informedconsent process for abortion.
A meta-analysis of the association between induced abortion and breast cancer risk among Chinese females
TLDR
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.
Association between abortion and breast cancer: an updated systematic review and meta-analysis based on prospective studies
TLDR
The current prospective evidences are not sufficient to support the positive association between abortion (including IA and SA) and breast cancer risk, and the combined relative risks (RRs) and corresponding 95 % confidence intervals (95 % CIs) were not sufficient.
Abortion history and breast cancer risk: Results from the Shanghai breast cancer study
TLDR
It is suggested that a history of several induced abortions has little influence on breast cancer risk in Chinese women.
Induced and spontaneous abortion and incidence of breast cancer among young women: a prospective cohort study.
TLDR
Among this predominantly premenopausal population of young women, neither induced nor spontaneous abortion was associated with the incidence of breast cancer.
Breast cancer in relation to induced abortions in a cohort of Chinese women
TLDR
There was also no overall increase in risk in women with induced abortion after first birth, and increases in risk were observed in such women, they were not statistically significant and could have been due to recall bias.
Induced and spontaneous abortion and breast cancer risk: Results from the E3N cohort study
TLDR
It is concluded that there is no relationship between breast cancer and induced abortion but that an association with spontaneous abortion is possible and may depend on menopausal status.
Induced abortion and breast cancer: results from a population-based case control study in China.
TLDR
A population-based case-control study in Shanghai, China, suggests that a history of induced abortions may not increase the risk of breast cancer.
Breast cancer risk in relation to abortion: Results from the EPIC study
TLDR
Overall, the findings provide further unbiased evidence of the lack of an adverse effect of induced abortion on breast cancer risk, and there was some evidence of a slight increase in the risk of breast cancer among women who reported having had 2 or more spontaneous abortions.
