Women, wouldn't you like to know your precise risk of developing breast cancer, ovarian cancer and endometrial cancer? And wouldn't you like to know what changes you could make in your life to reduce that risk? Researchers from the National Cancer Institute would like to help you. They've just published a study in the journal PLOS Medicine that takes a significant step toward that goal. Ruth Pfeiffer , a senior investigator in the National Cancer Institute's Division of Cancer Epidemiology and Genetics, and colleagues focused on the predictive value of more than a dozen variables, including a woman's body mass index , number of children she has, how long she took birth control pills, whether she used hormone therapy to treat symptoms of menopause, family history of gynecological cancers, and use of cigarettes and alcohol.

These days, it's just good to have a job. But remaining gainfully employed can take a toll on health, especially if your work has you up at odd hours and sleeping irregularly. Shift work, say two studies out this week, poses particular problems for women, who appear to be at greater risk of Type 2 diabetes and possibly breast cancer if they maintain work schedules that mess with their internal clocks. Researchers have uncovered a host of links between humans' respect for their circadian rhythms and their health prospects.

Are people who suffer from mental illnesses more likely to commit violent crimes? That question has been on the nation's mind since a 22-year-old community college dropout with a history of odd behavior was charged with shooting 19 people outside a Tucson supermarket this month, killing six and wounding Rep. Gabrielle Giffords (D-Ariz.), who police say was his target. The answer may seem obvious to the general public, given the popularity of movies, TV shows and books in which mentally unbalanced individuals are portrayed as homicidal maniacs.

Researchers have discovered a gene mutation that protects people in Southeast Asia against malaria in much the same fashion that a sickle cell trait protects Africans from the disease. But while the sickle cell protects against the frequently lethal form of the disease caused by the parasite Plasmodium falciparum , the newly discovered gene mutation protects against Plasmodium vivax , which is generally thought to be more benign. Malaria causes an estimated 1 million deaths per year worldwide, and at least half the world's population lives in areas at risk for the disease.

The 2009 H1N1 "swine flu" epidemic killed up to 203,000 people across the globe -- a death toll 10 times greater than initially estimated by the World Health Organization, researchers say. In a study published Tuesday in the journal Plos Medicine, epidemiologists used data on respiratory deaths in 20 nations to calculate a global mortality rate for the pandemic. Prior to this research, the WHO counted just 18,631 lab-confirmed cases of H1N1, a viral infection of the airways.

It will be an even 20 for Michelle and Jim Bob Duggar, who announced Tuesday that they're expecting their 20th child. The Duggars, stars of their own TLC show, are a source of fascination for some people, since super-sized families aren't the norm the way they were about a century ago. Michelle Duggar, you'll recall, didn't have such an easy time around with her last pregnancy in 2009. Daughter Josie was delivered early when it was discovered that Michelle had preeclampsia and gall bladder problems (Josie is now doing fine)

Want to gauge your risk for developing Type 2 diabetes? Don't just step on the scale - reach for a measuring tape too, a new study suggests. The circumference of your waist can tell you a lot about your chances of getting diabetes, according to a study published Tuesday in the journal PLoS Medicine . Health providers usually rely on body mass index to determine patients' diabetes risk, but adding waist circumference to the equation would...

Taking folic acid supplements for a year before conception reduces the risk of very premature birth by at least 50%, researchers reported Monday. Shorter courses of the supplement were not as effective, according to the study of nearly 35,000 women reported in the Public Library of Science journal PLoS Medicine. Folic acid's effectiveness in reducing the risk of neural-tube and other birth defects -- even without such a long course -- is long established.

With $3 billion in new pledges, world leaders say they believe that an ambitious goal to stop deaths from malaria by 2015 is finally within reach. A plan billed as the most comprehensive ever to tackle the mosquito-borne disease, which kills nearly 1 million people each year, was unveiled last week at a United Nations gathering of heads of government, global health leaders and philanthropists.

The twin plagues of economic hardship and low academic attainment turn out to be an inflammatory problem, not just for society but for the human bodies beset by them. And for many, including those in minority groups who disproportionately experience stunted economic and academic prospects, high rates of Type 2 diabetes are the common result, a new study says. The new research, based on a long-running study of British government workers, offers a partial explanation for a trend that is firmly established in industrialized democracies -- that where calories are plentifully available, those clinging to the lower rungs of the economic ladder are most likely to develop Type 2 diabetes.
