Studies show that women who worked night shifts face a significantly higher risk of breast cancer -- up to 60 percent higher, according to one study published by the National Cancer Institute. The thinking is that nighttime work, which entails exposure to light at night, interferes with the body's production of melatonin, the sleep-inducing hormone. Sleep deprivation and melatonin interruption in turn stimulate increased estrogen production, researchers believe.
Additional studies have linked low melatonin levels in general with breast cancer. The connection is strong enough that researchers are exploring whether taking supplemental melatonin can protect against 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?
