Pink News: Reproductive factors linked to breast cancer

Font size: Decrease font Enlarge font

A new Iranian study found women who have not given birth or given birth at an older age or undergone an abortion were at much higher risk of developing breast cancer.

Hajian-Tilaki K.O. and Kaveh-Ahangar T. from Babol University of Medical Sciences in Babol, Iran compared 100 newly diagnosed breast cancer cases with 200 age-matched controls for the difference in a number of reproductive factors.

The researchers found having first pregnancy at an older age and an abortion boosted breast cancer risk by 310 percent and 193 percent respectively.

On the other hand, increasing parity or the number of birth was found to reduce the breast cancer risk significantly.  Women with parity equal to or greater than 5 had their risk of breast cancer reduced by 91 percent compared with those nulliparous women or those who did not given birth.  And each additional birth reduced the risk by 50 percent.

The duration of breast feeding was found inversely associated with breast cancer risk.  But after adjustment for parity, the protective effect of breastfeeding was not observed. This could mean giving birth is more important than breastfeeding when it comes to preventing breast cancer.

The findings were reported in the April 3, 2010 issue of Medical Oncology.

Another case-control study conducted in Sri Lanka found women who breastfed 24 months or longer in their lifetime were 60 percent less likely to develop breast cancer compared with those who breastfed less than 24 hours.

The study was conducted by De Silva M and colleagues from the University of Colombo in Colombo, Sri Lanka and published in the June 2010 issue of Cancer Epidemiology.

De Silva et al. also found women who breastfed 12 to 23 months were 66.3 percent less likely to be diagnosed with breast cancer than those who breastfed 0 to 11 months in their lifetime.

When women breastfed for 24 to 35 months, the risk of breast cancer was reduced by 87.4 percent compared with those who breastfed 0 to 11 month.  Those who breastfed 36 to 47 months were 94 percent less likely to have breast cancer.

Women who had an abortion in the past were 242 percent more likely to have breast cancer and exposure to passive smoking could boost the risk by 196 percent.

The study involved 100 recent cases of breast cancer and 203 controls with age and parity matched.

Breast cancer is expected to be diagnosed in about 200,000 women and kill about 50000 women in 2010 in the United States, according to American Cancer Society.

More reports will be published here on foodconsumer.org in the National Breast Cancer Awareness  Month to help readers better understand breast cancer and how to prevent the disease.  

Critics like naturalnews.com suggested the pink month is no more than a commercial campaign to promote sales of a variety of products some of which can even promote breast cancer.

In the pink month, we's like readers to be aware of one thing, that is, breast cancer in many cases is preventable. Even if a person has a family history of the disease or genetic risk, he can still minimize the risk by following modified lifestyle parameters like diet.

Six Research Studies Linking Abortion to Breast Cancer


1st Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:

Fred Hutchinson Cancer Research & National Cancer Institute stated abortion is linked to elevated breast cancer risk in a 2009 published research paper titled, "Risk Factors For Triple-Negative Breast Cancer In Women Under The Age of 45 Years." Study was published in Cancer Epidemiol Biomarkers Prevention Journal 2009: 18 (4) April 2009.

Line 3-5 at the top left column of page 1163 in Cancer Epidemiol Biomarkers Prevention Journal, the study clearly concludes, ".....induced abortion & contraceptive use were associated with increased risk for breast cancer."

2nd Breast Cancer Research Paper Linking Abortion To Breast Cancer:
This study was conducted by Fred Hutchinson Cancer Research & was published in American Journal of Epidemiology. It concludes in part, “Among women who had been pregnant at least once, the risk of breast cancer in those with a prior induced abortion was 20% higher than that in women with no history of abortion (95% confidence interval 1.0–1.5). “

3rd Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:
This study was published in reputable Journal of Surgery Oncology 2009:
Turkish breast cancer study. Citation: Ozmen et al. Breast cancer risk factors in Turkish women - a university hospital-based nested case control study. Published in World Journal of Surgery Oncology 2009;7:37 Turkish study reported a statistically significant 66% increased risk of breast cancer for women with abortions. It concluded: “These findings suggest that age and induced abortion were found to be significantly associated with increased breast cancer risk whereas oral contraceptive use was observed to be associated with decreased breast cancer risk among Turkish women in Istanbul.

4th Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:
China breast cancer study by Xing P, Li J, Jin F. A case-control study of reproductive factors associated with subtypes of breast cancer in Northeast China.” Humana Press, e-publication online September 2009. The study’s abstract concluded: “Breastfeeding protected parous women from any subtype of breast cancer. Postmenopause and spontaneous abortion were inversely associated with the risk of luminal tumors. By contrast, multiparity, family history of breast cancer and induced abortion increased the risk of breast cancer.”

5th Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:
Sri Lanka - De Silva et al. Cancer Epidemiol. 2010 Jun;34(3):267-73. Epub 2010 Mar 24.
Title of research paper, “Prolonged breastfeeding reduces risk of breast cancer in Sri Lankan women: a case-control study.” Published by De Silva M, Senarath U, Gunatilake M, Lokuhetty D
Department of Community Medicine, Faculty of Medicine, University of Colombo, 25 Kynsey Road, Colombo, Sri Lanka.
It concluded, in part: “The significant factors associated with increased risk of breast cancer were: post-menopausal women (OR=1.74; 95%CI=1.01, 3.01); having an abortion in the past (OR=3.42; 95%CI=1.75, 6.66) and exposure to passive smoking (OR=2.96, 95%CI=1.53, 5.75).” In other words, as the Daily Mail UK reported, although the study was focused on the association between the duration of breastfeeding and the risk of breast cancer, other risk factors were discovered, and “the highest of the reported risk factors was abortion.” To read abstract: http://www.ncbi.nlm.nih.gov/pubmed/20338838

6th Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:

Babol, Iran (LifeNews.com) — Researchers in Iran have published the results of a new study showing women who have an abortion face a 193% increased risk of breast cancer. On the other hand, women who carry a pregnancy to term find a lowered breast cancer risk compared with women who have never been pregnant.
Title of breast cancer research paper is, “Reproductive factors associated with breast cancer risk in northern Iran” and the findings were reported in the April 3, 2010 issue of Medical Oncology.
Researchers Hajian-Tilaki K.O. and Kaveh-Ahangar T. from Babol University of Medical Sciences compared 100 cases of women who were newly diagnosed with breast cancer compared with 200 age-matched controls to review several reproductive factors.
The researchers discovered abortion significantly elevated breast cancer risks. Also, having a first pregnancy at an older age increases the breast cancer risk by 310 percent.

The abstract of the study concludes, "Nulliparity, late age at first birth and abortion were the most important reproductive factors associated with breast cancer risk; therefore, it is recommended to women with these risk factors to perform breast cancer screening tests earlier."
