A new system nimbly finds tumors masked by dense breast tissue that mammograms ordinarily can't spot - and at half the cost and with a vastly lower rate of false positives.

The technique, known as Molecular Breast Imaging (MBI), is especially targeted at the nearly one-fourth of women above 40 who have dense breast tissue, which allows malignancies to lie hidden until it's too late.

What's done with MBI is simply to inject a radioactive tracer into the breast. It's absorbed by the cancer cells, and the resulting "glow" is picked up by special cameras. The body excretes the tracer within a day. (Read more about Technique Finds Hard-to-Spot Breast Tumors)

A new study suggests that people who have had non-melanoma skin cancer may be at increased risk of developing other cancers, including those that affect other parts of the body.

The study is the work of Dr. Jiping Chen of the National Cancer Institute and is published in the Journal of the National Cancer Institute. (Read more about Skin Cancer May Lead to Other Cancers)

New research by the Partnership for Prevention suggests that over 100,000 Americans lives could be spared each year by increasing five preventive steps. The report claims that there are serious shortcomings in disease prevention across the US, especially for ethnic minorities.

The greatest preventive impact would be 45,000 lives saved from more adults taking a daily low dose of aspirin to prevent heart disease. Smoking cessation would save 42,000 lives. Adults having regular annual cancer screenings would save 14,000 lives a year. For adults aged 50 of over, an annual flu shot would save 12,000 more lives. Additionally, nearly 4,000 lives would be saved by increasing the number of women aged 40 or over who have been screened for breast cancer in the past two years. The report also suggests that 30,000 cases of pelvic inflammatory disease could be prevented if sexually active young women were screened for chlamydial infection in the past year.

Though studies have linked secondhand smoke to death an illness, a new study suggests that very little is done by parents to protect their children. Appearing in the latest issue of the American Journal of Public Health, the study examined the smoking histories of the adults in the homes, exposures to secondhand smoke inside the house, around the community, and attitudes toward smoking. Researchers used air-sampling technology to examine nicotine levels in the homes and hair samples to measure individual levels of exposure in non-smoking women and children.

A recent report by health provider BUPA has found that people's worries are damaging their health by causing sleepless nights, loss of sex drive, and erratic eating habits. The 2007 Worry Report demonstrates that almost one in five people constantly worry about numerous things, and more than half feel they worry more now than five years ago. Half of the people surveyed this year, which is 6% more than in 2006, claimed they were more worried about their health and their family's health than about other concerning issues such as climate change or terrorist attacks. The survey finds that almost three quarters of people worry, but around 19% admit to worrying all the time or about a number of things. (Read more about Worried Sick?

A recent report from the Institute of Medicine addresses the toll that cancer therapies have on patients' mental and emotional state that may potentially cause other health problems. Cancer treatments save and prolong many people's lives; however, care that focuses solely on eradicating tumors without acknowledging a patient's well-being can increase the patient's suffering and affect their ability to follow through on treatment. The report proposes that oncology care providers use a new standard of care that accomplishes three goals: screen patients for distress and other problems, coordinate and connect patients with health care or service providers who can treat these problems, and periodically re-evaluate patients to determine if patient care needs adjustment.

A recent study by Kaiser Permanente Researchers has found that the effects of alcohol on breast cancer are the same, regardless of whether a woman drinks wine, beer, or liquor. The ethyl alcohol found in those drinks and the quantity consumed are the factors that weigh heavily on breast cancer risk. Researchers believe the increased risk from three or more drinks a day is similar to the increased breast cancer risk from smoking a pack of cigarettes a day or more. They claim that "Population studies have consistently linked drinking alcohol to an increased risk of female breast cancer, but until now there has been little data, most of it conflicting, about an independant role played by the choice of beverage type."
