Women whose breasts appear dense on mammograms have a higher risk for some aggressive breast cancers.

One of the strongest known risk factors for breast cancer is high breast density — that is, relatively little fat in the breast and more connective and glandular tissue, as seen on a mammogram. Now, a study has found that higher breast density in postmenopausal women increases the risk of specific types of breast cancer, including some that have a relatively poorer prognosis.

The bad news is that — like gender, race, family history, and genetic endowment — breast density is pretty much out ...

Ugly and annoying, warts never seem to go away fast enough. Treating them may help speed their departure.

Warts are generally harmless and often disappear on their own over time, but they're unsightly, and some, like those found on the soles of the feet, can make walking and exercise painful. Getting rid of warts can be a challenge, but fortunately, the most effective treatments are the least invasive.

Wart anatomy

Warts grow only in the epidermis, the upper skin layer. A typical wart has a raised, rough surface. (Some, like those on the face, may be smooth and flat.) ...

Can gentle vibration improve bone density and prevent fractures after menopause?

Soon you may be hearing a lot about low-intensity vibration therapy for strengthening bones and reducing the risk of fractures. Two low-intensity oscillating devices designed for home use are coming onto the market, and the Agency for Healthcare Research and Quality (AHRQ), which advises the federal government on health care matters, is expected to issue a report highlighting the evidence as well as the many unanswered questions about this unique approach to bone health.

These low-intensity vibration devices gently stimulate muscle and bone when you stand on them. They ...

About a third of people over age 65 fall each year, and foot problems are one of the major causes. A foot-health program combining orthoses (shoe inserts), footwear advice, and foot and ankle exercises can help prevent such falls, according to an Australian study published online June 16, 2011, in BMJ. Many guidelines for fall prevention suggest that older people who've experienced falls or have difficulty walking should have their feet and footwear examined by a podiatrist (foot specialist), but they don't indicate what, specifically, should be assessed or what people can do to prevent falls. The Australian study helps ...

Vascular disease increases the risk of age-related cognitive decline, but women who already have vascular problems can still gain cognitive benefits from daily exercise.
