Though still rare, when breast cancer shows up in women in their 30s, it's not a kinder, gentler form of the disease. Quite the opposite. Scientists are beginning to understand why this is and what interventions might calm its cruelty.

Cancer surgery is a fine line between removing too little and leaving cancer behind, and removing too much at cost to the patient's quality of life.

Figuring out the molecular puzzles that can change a healthy cell to a cancer cell would be difficult even if you could watch the process happen.

Drugmaker Roche has halted a pivotal late-stage clinical trial for an experimental medication designed to increase "good" HDL cholesterol after the study revealed it did not offer a benefit.

When a woman has a baby, the cells of her unborn child circulate in her body for decades after childbirth. Likewise, some of her cells are in the body of her child for years, too. This is called microchimerism.

Hundreds of proteins on the outside surface of cells interact with the world, moving things in, moving things out, acting as relay stations for signals to grow, move, divide and die.

Common sense would say that hiring an extra person to oversee a patient’s care would cost a great deal more. However, new research suggests that integrative health care will actually lower cost and improve results in certain cases.

When it comes to feeding babies, it's not just what you feed your child but how you feed your child. Even breastmilk in a bottle affects weight gain differently than milk directly from the breast.

A recent study has found that infants fed only by bottle gained more weight each month than if they were only breastfed, regardless of whether the bottle had breastmilk or another food.

Of course you adore your adorably chubby little toddler, but you do know how much of that chubbiness is normal or whether your child might actually be overweight? Many moms don't.

A recent study found that the vast majority of mothers whose toddlers were overweight had a different perception of their little ones and could not correctly identify an image representing their baby's body size.

Erin Hager, PhD, of the University of Maryland School of Medicine, led the study of 281 pairs of moms...

Depression and dementia often happen to the same people. Does this mean that depression is a risk factor for dementia?
