In April, the U.S. Food and Drug Administration (FDA) approved a new screening test for colon cancer, making it the first blood-based test for this type of cancer.

A decline in sex hormones is a natural part of growing older. Still, it's only natural to want to feel robust, mentally sharp, and healthy as we age. So it's no surprise that hormone therapy—which has been touted by drug companies as a way to restore youthful vigor, first for women and more recently for men—has generated so much interest.

It appears people with the highest levels of physical activity have lower rates of cancer of the esophagus, lung, kidney, colon, head and neck, rectum, bladder and breast, compared with people with the lowest levels of physical activity.

A group of scientists wants to develop technology to create a synthetic human genome, which could lead to improved organ transplantation, vaccines and medicines, and to new ways to fight cancer and infections.

It appears that four healthy habits—getting 150 minutes of moderate-intensity exercise per week, maintaining a body mass index between 18.5 and 27.5, no smoking, and drinking only in moderation—may prevent many cancer cases and death in white people.

Miscarriages can be devastating — especially for women who experience recurrent miscarriage, defined as three or more in a row. Doctors used to give these women supplements of progesterone, a hormone that helps maintain a healthy pregnancy. However, a recent study has confirmed that these supplements don’t improve pregnancy outcomes. For those who experience recurrent miscarriage, the best solution may be to simply keep trying.

The hype around human growth hormone (HGH) comes from a few studies that showed HGH injections can increase lean body mass and shrink body fat, which led to claims of HGH as an “anti-aging” hormone.

Body mass index (BMI) is still the best way to assess body fat for most people.
