Breast Cancer Risks

Quick summary

Knowing the risk factors that contribute to breast cancer can help you evaluate the likelihood of getting the disease. In some cases, it's possible to make changes now that will improve your chances of avoiding it. Here's what researchers know about breast cancer risks.

Menstruating longer, having children late

Breast cancer risk is affected by changes in hormone levels throughout life. Longer periods of high estrogen levels lead to a higher risk of breast cancer -- for example, women who had their first period before the age of 12, entered menopause later than 55, and either didn't have children or had their first child when they were older than 30. In contrast, becoming pregnant at an early age or having multiple children decreases a woman's risk of breast cancer.

Similarly, breastfeeding for one and a half or two years affects a woman's hormone levels and thus decreases her breast cancer risk.

I would be hesitant to believe that a high fat diet raises your risk. It's sugar that directly feeds cancer cells because they can't live without it. So the fats they were studying were probably low quality PUFA fats and trams fats. If you eat high quality fats like coconut oil, avocados, olive oil, and animals fats from healthy free range animals that will help you stay healthy I think. Never over generalize what the study actually measured.

Worried Sis, with such a strong family history of recurring BC in your family, it would be a no brainer for you all to be DNA tested for the BC gene mutations BRCA1 and 2. Both of my sisters and I are carriers and have all had BC, multiple times for my sisters. One sister had it 4 times, with the last (primary) cancer being 25 YEARS after the the previous ones. Follow the health suggestions in this article, and get tested!

80% of women who get breast cancer have NO risk factors. The 20% who do usually have only 1. We are ALL at risk. I nursed had my babies before 30, exercised, did not consume alcohol, smoke or have any family history. It's what we need to be telling women. It's our environment, not our genetics.

Heart disease kills more women than all the cancers combined. Worry more about heart health.

Sad that you left out that several reputable studies (mostly out of the politically charged USA) have shown some linkage between abortion (especially of a first pregnancy) and breast cancer. The physiology of the maturation of breast tissue through first pregnancy makes this almost a common-sense connection. While science is unclear in several of the risk factors you presented, this is the one you chose to leave out. I understand you would be attacked by certain groups. But don't you think you owe it to young women who may want to weigh these factors in their decision-making?

What about women who have had an aboration? That is a possible fact in breast cancer.

Why did you not mention the increased risk due to use of oral contraceptives? One of the deadliest forms of breast cancer, triple negative BRCA is linked to that. Also why did you not mention the increased risk caused by abortion? There are a multitude of studies on this which were suppressed in 2003 by the NCI. Dr. Swinton in January of 2009, reversed her position on the abortion-breast cancer link and now states there is a link.

My mom and sister both have had breast cancer.My mom twice .My sister going through it for second time. If I had known this eleven years ago I would have gotten tested for breast cancer. I myself went through breast cancer once. My doctor told me Ii won't come back after so long. How can she say fhat? I'm not sure on how long between moms that it came back, but my sister had hers the same time as me and now it is back. What are the chances of this happening ? Thank you for letting us know these helpful, interesting and very informing articles.

My maternal grandmother died from cancer of the liver. A doctor said it was secondary cancer, which began from breast cancer. My mother died at the age of 82 years, but did NOT have either cancer of the breast or liver. I am now 64, and my daughter is 41, but neither of us have shown any signs of either cancer. What risk do we stand?
