Extra weight lowers Breast Cancer risk before menopause, increases it afterward

Women who are heavier in young adulthood have a lower risk of developing breast cancer before they reach menopause, new research shows. The finding, published in the Nov. 27 issue of the Archives of Internal Medicine, confirms and expands on previous research suggesting that larger body size before menopause helps fend off breast cancer. That's not a license for women to gain weight, however, experts stressed. "We have to remind women that obesity is pretty much bad for everything else and, as soon as you become postmenopausal, obesity is one of the strongest predictors of breast cancer," said lead researcher Karin B. Michels, an associate professor of obstetrics, gynecology and reproductive biology at Harvard Medical School and Brigham and Women's Hospital in Boston. --Click the title of this post to read the full article from its source--

Red Meat-Breast Cancer Link Is Junk Science

“Breast cancer risk linked to red meat, study finds,” headlined the Washington Post’s front page last Tuesday. “Younger women who regularly eat red meat appear to face an increased risk for a common form of breast cancer, according to a large, well-known Harvard study of women's health,” began the Post’s report. The researchers studied 90,659 women aged 26-46 over 12 years. Red meat intake was assessed three times via self-administered questionnaire during those 12 years. By the end of the study period, 1021 cases of invasive breast cancer had been documented. Contrary to the Post’s headline, however, the researchers actually reported no statistically significant correlation between red meat intake and all types of breast cancer.
Now you might think that the researchers would have stopped at that point and moved on to some other more promising health scare. Instead, they opted to dig deeper into their data. They seemingly struck health scare gold by mining an apparent statistical correlation between red meat intake and so-called “hormone receptor-positive” breast tumors – that is, tumors in which hormones like estrogen and progesterone are thought to play key roles. --Click the title of this post to read the full article from its source--

Flame-grilled foods linked with higher risk of breast cancer

Women who eat flame-grilled meats may run a significantly higher risk of developing breast cancer compared to women who never eat grilled meat, according to a new study. Researchers from Johns Hopkins University examined the diets and eating patterns of 312 women with breast cancer and 316 women without the disease, and found that women who ate flame-grilled foods more than twice per month experienced a 74 percent increased risk of breast cancer compared to women who never ate flame-grilled foods. --Click the title of this post to read the full article from its source--

Heavy Red Meat Consumption Raises Breast Cancer Risk Significantly

If an American woman consumes one-and-a-half servings of red meat each day, her risk of developing breast cancer is double that of a woman who consumes three servings per week or less, say researchers from Brigham and Women's Hospital and Harvard Medical School, USA. You can read about this new study in the Archives of Internal Medicine.The scientists examined data on 90,000 pre-menopausal women in the Nurses Health Study II (1989-2003). All the participants had completed questionnaires which included details on their eating and drinking habits. The questionnaires were first filled-in in 1995, and then in 1995, and finally in 1999. The study also had an update, every two years, on who had developed breast cancer. It was also possible to determine whether those who had developed breast cancer, did so as a result of an oestrogen or progesterone trigger. A total of 1,021 women developed breast cancer, of which 512 were oestrogen and progesterone-receptor positive, 167 were oestrogen and progesterone-receptor negative, 110 mixed, and 232 unknowns. --Click the title of this post to read the full article from its source--
