When my son and daughter were youngsters, once a year I'd have a disagreement with their pediatric dentist. He wanted to do routine annual X-rays, and I would protest because neither child ever had any cavities. His response: Dental X-rays are an important diagnostic tool, representing a small speck in the sea of radiation that we receive by inhabiting planet Earth. It turns out we both were right. Dental X-rays are essential for detecting serious oral and systemic health problems, and generally the amount of radiation is very low. But new thinking on dental X-rays is that the "one size fits all" schedule is outdated.

Patients with metastatic breast cancer who respond to chemotherapy are unlikely to see any additional benefits from surgery or radiation therapy, according to leaders of a new clinical trial. The randomized, controlled study, which was presented Wednesday at the San Antonio Breast Cancer Symposium , was intended to settle a long-running dispute among oncologists about the best way to treat women whose tumors had spread to other parts of their bodies, said Dr. Rajendra Badwe, director of the Tata Memorial Hospital in Mumbai, India.

Ever wonder why some people, even under adverse circumstances, set goals and achieve them effortlessly? Some of them, undoubtedly, are hard-wired to succeed. They just set themselves in a direction and their mind handles the rest. But that ability is atypical; most of us, at one time or another, are daunted by illness or other mental or physical challenges. That's where hypnosis can come in. Experts in a variety of fields say that patients become highly focused and open to suggestions when they are in a trance-like state.

All the amenities of modern medicine are available at a new West Los Angeles hospital. There's 24-hour emergency care, a team of surgeons, psychology and physical therapy units, MRI and CT machines, one of the top oncologists in the country. Medical assistants busily roam the halls, soothing patients' fears with smiles, kind words or gentle touches. But they have to watch out: The patients can bite. They're dogs, cats and other pets being treated at the VCA West Los Angeles Animal Hospital, which at 42,000 square feet is the largest pet hospital west of the Mississippi River.

The sun has erupted more than two dozen times over the last week, sending radiation and solar material hurtling through space - and scientists say more eruptions may be coming. This shouldn't be unusual. After all, we are technically at solar maximum, the peak of the 11-year cycle of the sun's activity. But this has been a noticeably mellow solar maximum, with the sun staying fairly quiet throughout the summer. So when our life-giving star suddenly let loose with 24 medium strength M-class solar flares and four significantly stronger X-class flares between Oct. 23 and Oct. 30, it felt like a surprise.
